First Ever AI REBIRTH SCREEN on Original NES Tetris
Vložit
- čas přidán 4. 06. 2024
- This is BetaTetris with 30 Hz tapping and 300 ms reaction time playing to level rollover (aka Rebirth Screen).
The crash dodging strategy used is:
- Pushdown at level 158 transition and every piece in level 253 (using BetaPushdown)
- Flash the next box at level 155,156,159 transition, every non-transition line clear in level 156-158, and every piece in level 249,255
- Score only singles from level 166 transition to level 173 (using BetaSingle)

Answering a few common questions here:
Q: Why does it left well?
A: The reason is pretty complicated, but simply put, I used a left-well-preferring NN to generate the tablebase since it is my best NN at that time, and as a result the tablebase also prefers left well.
When training a neural network, whether it prefers left or right well depends on which well it discovers first in the training process, which is essentially random. In fact, the BetaTetris NN featured in this video prefers right well if playing without the tablebase.
Q: Why does it change from left well to right well, or vice versa?
A: I mirrored all the boards in the tablebase, so the tablebase can actually play both wells. Whenever it thinks left / right well is better for the current situation, it will go for it.
(The piece movements are not symmetric, so even with mirroring the board quality of left well are still better than that of right well.)
Q: What happens if you keep playing after rollover? Is it the same as if you start a fresh new game from level 0?
A: It would be almost the same, except that the 810-line level will be at a different level since the line count is different. (and some trivial ones such as piece statistics and starting score)
Q: The color palette of display levels 146 & 210 should be Dusk, not Dust?
A: Yup, that's a typo. In fact, I copied the color names directly from my previous video and never realized there was a mistake :)
Q: How to solve the emulator discrepancy problem? Is it possible to run the AI on console?
A: The method is to do a console verification. For example, if someone took the BizHawk input file in the description, replay the imputs on the console and it runs perfectly, then we will know the emulation is accurate.
Once the console verification is done, it is definitely possible with proper tools to sync the console with the computer to give the inputs (though I don't have a console nor the hardware to do this).
Q: Does this mean it is possible to play infinitely?
A: Any AI will be prone to topout if it encounters a bad enough piece sequence. However, it is possible to design a TAS for true infinite play, using the fact that the level pattern will cycle every 17600 lines (after the first level-up). If one can to find an input sequence to
1. Get to the exact same board & next piece after scoring 17600 lines
2. The number of scored singles, doubles, triples and tetrises in these 17600 lines are all multiples of 10
3. Pause the game appropriately to make the in-game RNG loop back to the same state after these 17600 lines
then the game state will essentially loop back, hence achieving true infinite play by repeating the inputs of these 17600 lines.
Q: Why did the screen glitch out at 1:09:26?
A: That's an encoding glitch when I exported the edited video (possibly due to a bug in my video editing software).
I am one of the few who prefers left well IRL. Every time I start to set up right well it devolves into left well.
@@boopydoopy2488Yes, we made you to prefer a left well. Trying to make a right well is just you trying to challenge your own programming.
@adrien_1018 infinite play is (sadly) not that simple (unless you fix the crash in some way).
Is it going to ever be possible for a Tetris player to use the select button and also push down? Also, what does the select button do again I missed that part.
@@wiirambo7437 the crash dodging strategy still works after level rollover, so crash should not be an issue.
So this AI avoids all the crashes, without RNG manip, without knowing pieces beforehand (aside from the 1 next piece) - that's hype
Looks like it avoids it by taking singles and manipulation of push down points.
@@jjeastside Insanely weird for you to say "manipulation" of push down points in response to a comment talking about RNG manipulation
This is the only known way to dodge the crashes with maximum probability. It's not "manipulating", it's just "holding down at certain points to avoid crashing"
The entire crash-dodging strategy is outlined in the description box.
@@codetaku I don't mean manipulation in terms of an unfair or cheating way I meant the first definition of manipulation which is to a handle or control in a skillful manner. Instead of rng manipulation to get certain pieces to avoid game crashes it is using piece movement manipulations in order to handle game crashes.
I think you may have jumped to conclusions and took my comment in a negative manner to diminish the impressiveness of the AI.
@@codetaku To your other comment of it being the the "only way to dodge crashes with maximum probability" is also incorrect. There are other alternative ways that can be used to handle the game crashes such as multiple players being plugged into the console and flashing your next queue. There is an excellent video by EricICX called "The secret second ending of tetris" and a comment on the video by Fractal which demonstrates these techniques.
@@codetaku its sounds like you're very passionate about tetris and I am too but please remember to be courtesy and give others the benefit of the doubt when making comments like these.

@@christianepps3584 idk, I just watched the video
I love that it's possible to be so good at Tetris that you start breaking the game itself, and if you can handle that long enough, you can fix it too.
NEStris is actually just an assembly coding challenge if you are good enough. It's only a game if you're bad at it

Calling it now by 2027 some mad lad will have achieved a double rebirth
@VideoGamer110 in the future, it will stop being a matter of who can get the most rebirths...
With how far we've come in tetris by now, there'd be no surprise if, for example, Alex T. manages to pull off a rebirth in a human game.
It's basically inevitable at this point. Alex T did 155 to 255 reset, he can play start to 155, so just a matter of getting both in the same run
@@GK-gc9cvcorrect me if I'm wrong but that was on the modded version
@@peachparee7647 It's humanly impossible to consistently getting passed all the crashes. From level 155 to 159 are possible crashes by making a single. Even getting to that point in your run is super hard, but getting through all possible crashes is absurd. And I'm not even talking about crashes on levels 249, 253 and 255. So yeah, he uses modded version.
In the modded version it will happen within like a year but crash dodging is on a whole other level
36:07 this level is called Blue Scuti!
Honestly, we should change the palette name to that. The palette has blue in it, and this level is most known as the level that Blue Scuti crashed at.

Get in the game

That was impressive. Discovering the state of the Tetris scene some years ago was crazy enough (RIP Jonas and his rare footage of achieving a game crash). Finding out again when Scuti made the news was flabbergasting. It’s truly a game of all time, not only because of its everlasting appeal but because the limits are still being stretched after decades. At least when it comes to bot play, I think we’ve reached the final major milestone now with rebirth.
did jonas crash the game? where can I read more about that
He crashed the game (at least, made the game malfunction) due to some unknown reasons, but definitely not the high-level crash we're talking about nowadays.

Been looking for a rebirth video since getting hooked on NES Tetris after watching Summoning Salt's video.
The glitch colors look very cool.
and the fact that it’s left well is even more impressive
Is it just a flex or is there a reason for this?
@@dennisamelunxen8283 since the pieces are biased to the right side of the board it would make sense to build the stack on the left and send tetrises to the right, which is what a lot of people do in competitions
@@dennisamelunxen8283 Neural network happened to find left well first, not smart enough to realize it could use the other side instead.
these glitch color palette names are SENDING ME
Since "infinite play" is theoretically possible by cycling back to Level 1, this leads me to believe that the final frontier for Tetris play will eventually become Time Defense: Play for as long as possible without topping out or crashing the game.

Hello. Thanks for the video.
I found this one after watching Summoning Salt's video on the history of Tetris world record
Amazing video I didn’t know how common confetti was and I also didn’t know how large the gap was after the first cluster of crash spots and I also didn’t know the very end was possible without rng manipulations!
We are definitely years away for a human achieving rebirth on vanilla rom
Now, let's see who the first mere mortal will be to reach rebirth...
(33:44, 48:15) Whoops, the name of that dark color scheme is "Dusk", not "Dust".
(46:47) I like the Bubblegum palette myself.
SRA jumpscare
And yeah, I agree. If I were to add a new official palette to the rotation in this game, it would be the bubblegum one.
33:45 Dust 😂😂😂
44:17 As it enter the RED pallet, 2 pieces are on 666
On the topic of which emulator is most accurate, would it be possible to train these models to use actual hardware either by interpreting the video output or by modifying the console to read out the gamestate in memory
@adrien_1018: Would fixing the score calculation (e.g. by replacing it with a faster routine) fix the crash conditions? AFAIR there's basically some code saying add those points as often as the current level number?
if there's a faster routine that can speed up calculation such that you can have it work as intended again (like levels 0-19), i'd say it's reasonable that those crashes would be fixed
Amazing video, thanks!
impressive work !
1:14:58 now, this means we can technically play forever without losing
All those text glitches could be part of some curse horror game story.
This is some insanely impressive stuff. The crash avoidance is cool!
I love some of these color palette names. My fav is probably "Internship at Marie Curie's Lab"
Thanks , i rly wanted to see this , if you do a second rebirth screen is nothing different? it just becomes an infinite loop?
It would top out eventually but theoretically possible
it will be almost the same, except the 810-line level will be In a different place.
this is amazing. btw i think greg rlly likes spaghetti for no reason (he named like all of the levels after spaghetti)
1:05:21 I can't read the subtext due to pixelization, but I think it says something about how it's sad Jonas isn't around to see what he would do with these new discoveries. And I agree. RIP Jonas.
Also, I know it's a pain to play but Dusk is probably my favorite glitched color palette. I like how the colors work together.

Oof, the fact that the 810 line level is also one of the levels with a charcoal colour pallet is going to be killer if anyone ever tries to do this manually. It's like the final boss stage of Tetris.
Crash dodging is much much harder than 810 lines on charcoal even though that itseld is insanely difficult
Does this ROM have anti-drought provisions, like 7Bag? Because my original NES cart definitely droughts me on I-pieces every time. This gameplay feels a lot more relaxed.
vaporwave+ is such an awesome color scheme, blue, orange and white
It's like detergent! Which you definitely need after 810 lines of charcoal...
I saw that this ai didn’t have a preference for left or right well, and that it was meant to play on the super kill screen. Are there any videos of it doing so, and does it still play with a left well then?
Would it be possible if you could make a video showing how everything behind this works, like how this AI was built and how it interacts with the game and everything? Very interested to know indeed!
Beautiful
That is so amazing
This was so entertaining
Woaoo esto fue genial !!! Cual sera mas jugable ? Consola o emulador movil x q lo e jugado en movil pero cuando empieza el 20 es otra cosa buen video!
As someone not computer minded whatsoever, it so fascinating to me how someone developed a program to beat a game like this. I could never get my head around the computing going on inside a games console or a new pc.
What exatly are the situations when Tablebase fails/falls short?
It makes sense to me, that it wouldn't know about the freezing problems. But in what ways is it insufficient under "normal" circumstances?
Also, when the rollover happens, is it a *complete* rollover? Or is it effectively like a new seed? I'm guessing the RNG has a different cycle length than getting through all levels once?
great question damn
Simply put, tablebase is better at clean boards, not so good at messy boards (where its "confidence level" is low), and is unable to play at unseen boards, so it needs an NN as a backup. For more details, check the FAQ section in its repo: github.com/adrien1018/betatetris-tablebase/tree/crash-dodge
The rollover is almost the same as if you start a new game from level 0, except the position of the 810-line level will be different.
@@adrien_1018ah, that makes sense, thanks
As someone who always tosses his pasta in a pan to give it extra burn before eating it, I greatly approve of 41:09 !
I would be interested to see what happens if there is a chance of the input not being registered correctly. A human will avoid some strategies because they cannot be sure to execute the inputs with 100% accuracy. If the AI were to have e.g. a 1% chance of the input not registering, how would that affect the strategy of its gameplay? How much more conservatively would it play?
Have you let it play the rebirth screen to see what else weird the tame will do?
41:43 "Alright! Fourth game cra--" *tops out*
1:05:20 I need the context, because I don't understand what happened 🤔 Jonas put down a single T piece and beat NES Tetris how exactly..?
what was that on 1:09:26? it looks like the screen glitched
23:09 Is it posible in the vanilla game for so manu square pieces to appear euther in a row or one tetramino appart?
Or at 25:52 with the long pieces?
Can you explain what do you mean by "manu square pieces"?
And I suppose you meant "either one row off or one tetramino off" with your question, but what one tetramino apart could be? tetramino means blocks with 4 squares connected, so it's exactly all pieces in tetris. Maybe you thought tetramino was just I piece and meant "one column off"?
the confetti glitch with the tetris landing sounds so scary and idk why
Okay, even right at the start, some of those moves are unreal! (0:22)
I wish my Confidence Level was that consistently high.
"México according to Hollywood" HAHAHA
One thing I'm curious about is how much you can nerf the AI by and still have it rebirth consistently. 20Hz and 400ms reaction time? 15Hz and 500ms reaction time?
LMAO I was like "Why is the game lagging?" at the end
Do you retain the multiplier at the Rebirth, or does it return to the lowest amount?
Lady friend: Hey, you can come crash at my house if you want
This guy: Ok cool. *starts to set up his AI-Tetris Control room*
Lady friend: what are ya doin'?
This guy: I'm gettin' ready to crash, of course!
i must ask because lots of videos have different colors for level 235... is the true palette for level 235 charcoal color, green, or something else?
If with desync,it uses pattern level 234 which is charcoal level 2, if it's fix, then the pattern uses 235 which is greeeeen
1:14:58 boom rebirth of Tetris.
So, when line count reverts back to 0, doesn't corrupt any part of the ram? I was hoping for some crash that's unavoidable. Great video btw. Thanks for making. Also watching it x4 makes it sound like a music
don't add comma after so when starting sentences
How fast is 30Hz tapping compared to human rolling or hyper-tapping?
Hypertapping is not even close, rolling is equivalent at its peak, but only a couple people can reliably hit that peak. Thankfully due to it being in short bursts, that shouldn’t be an issue.
AlexT got to the rebirth in a practice run
he started on level 100 something so it's not from the start
That's different though, that's on a mod that can't crash. This AI is playing with crashes possible. It's unlikely anyone could ever reset the game with crashes active like this AI did. But resetting the game with crashes modded out will be an insane feat when it inevitably happens
I happen to love playing Left Side Well since I taught myself to do it over the past year or so, but why would it be advantageous to an AI? I thought right-side well was considered optimal for piece placement speed.
It's not. Left side well is just a flex here
I've never heard of this Tetris-solving AI
Christ... this pretty much means a true TAS for this game or something would be far longer than we thought....
Possibly even endless
I watched that clip of Jonas crashing the game. Thank you for the reprieve from CHARCOAL.

34:17 is not when crash zone begins, it's time for explanation of crash. You seem to have confused it. Also, you put the 100-line desync time, not when the level number becomes yellow.
But, level 155 is the first level that could crash the game. And level 155 is shown at 34:17.
@@starrekt2037 Level 155 is at 35:39. Or you mean something else? Maybe I'm not understanding something, correct me
@@user-ng4sb5nl2o oh, sorry, I correct that soon.
very neat!
Did I get this right? There's an array of level numbers and the level indicator picks a number from that array, and when the real level number goes over the limits of that array, it reads memory after that array as if it was still part of that array?
If so, is there a reason why it wouldn't just display the level number itself? I realize it's not written in a modern language but just to demonstrate my point, to me it seems silly to display levelNumbers[n] when you could just display n.
Not an NES programmer, but my impression is that there's no "displaying n" in the modern sense like a print function. Everything displayed has to be a tile.
Or think of it like that:
On MS-DOS, you can tell the computer to "print text", because the "font" (which is effectively just tiles with how the characters look like) is contained in the hardware ROM, and the BIOS contains routines to display the text from these "tiles". On an NES there is no BIOS (even if there is one, "text printing and fonts" isn't its concern), and the game has to do that part of the work itself.
@@jacquelineliu2641 Ah, yes. That makes a lot of sense. Thanks.
The game has plenty of decimal counters so i don't know why they didn't make the level number like that too. Probably optimising for _something_
The game uses BCD format (binary-coded decimal, which means the numbers is stored so that when it is read in hexadecimal, it appears to be the original decimal value) when displaying the numbers, so a lookup table is needed to convert a normal number into BCD format
There’s a 17 minute level in the palette of Charcoal 2, absolutely brutal
It was worse on AlexT's first time making it to the 810 line level on the modified version of the game, he got the 810 line level on the green level, and he wasn't even ready for it cuz he thought the modified version removed the 810 level because he expected it on charcoal and when he didn't get it, he just assumed the level was removed from the game.
Amazing!!!
Wow, more than 500 tetrises!
33:44 Typo: "Dust" --> "Dusk"
Edit: Same thing with 48:15
I still think Burnt Spaghetti should've been called S'more, but that's just me.
Edit: And Christmas but Green with Envy should be The Grinch.
24 mns in, cheering on tetrises to catch up with single lines
that's pretty cool!
