Cart #spaz48_tetyis-2 | 2020-02-06 | Code ▽ | Embed ▽ | No License

(Update 1.01: Fixed a bug that caused an out of memory error with particles disabled. Thanks to @dw817 for finding it!)

So, here it is, my first ever fully completed cart. I have a real bad habit of starting lots of things and never finishing them, and this was destined to be just another one of those things. I started work on this about a month or two ago, and did most of the work back then. I decided I needed a bit of a break from my current project and thought, hey, why don't I go back and finish this?

I've learned a lot since then, and generally improved a bunch, so most of this code is a mess, and doesn't use things it really should like objects, but, everything functions well enough at least. It's super unoptimized though, mostly because I was under the assumption there was no CPU limitations in Pico-8, and going back to finish it up, I didn't really bother fixing that. The particle system is my own, written for the main cart I've been working on, but the background previously was a stolen tweetcart (the function was even called "stolentweetcart()") I was using as a placeholder. It was distracting anyway, so I replaced it with the particles and used them to make a few other things nicer as well.

The main goal here was to make it compliant to the 2009 Tetris guideline (a big document the Tetris company uses that says exactly how a Tetris game should be made) though I disregarded that going back to it, so it's halfway or so there. Also, SRS isn't implemented properly, it's good enough but it's not perfect, and the title is a typo I thought was funny so I rolled with it.

Anyway, enough of my rambling, hope you enjoy!


  • Z, X: Rotate
  • Z+X: Hold
  • Up: Hard drop
  • Down: Soft drop
  • Left, Right: Move

Nice work. I really liked the intro and the smooth drop.

P#72732 2020-02-04 21:15

Try as I might, I wasn't able to get my score high enough to see if you dealt with > 16384 :)

P#72733 2020-02-04 21:36

There's an issue with the Super Rotation System implementation. I wasn't able to do a T-Spin triple. Other than that, the graphics are really impressive and the gameplay's very good!

P#72734 2020-02-04 21:36

@deraj Thank you! And you mean the integer overflow? I did somewhat deal with that, the last 0 in the score is fake, so it goes up to 32,7680. I was going to have it give you points for soft dropping and hard dropping, but that had to be cut specifically because of the overflow.

@TheV360 Yeah, that's exactly what I meant when I said it wasn't implemented properly. T-Spin triples don't really work, except they sometimes do when the tetromino is a block higher than it should be for one? That was something I did wrong back when I first worked on this like a month ago, and I didn't really feel it was worthy of addressing now since the rotation is good enough and T-Spins aren't counted.

P#72737 2020-02-04 21:42

I'm impressed, nice work! The only issue I have at the moment is the fact that I don't seem to be able to place pieces very high on the far edges of the screen, even when the next piece can spawn just fine.

P#72766 2020-02-05 13:24

@JWinslow23 Thanks! And yeah, it's got some quirks like that. I'm very aware that a lot of it needs to be rewritten, it was really just a coding exercise I decided to polish up and release. Someday, I may make an update that fixes it up and rewrites some of the wonky parts and etc, and add other modes and stuff like that, but for now my focus is in other places.

P#72767 2020-02-05 14:00

LOVE the intro to this!

P#72805 2020-02-06 01:13

The good news is I =REALLY= like Tetris or this might've not been found for a-while.

P#72806 2020-02-06 01:28

@gate88 Thanks! You can thank my hardcore procrastination for that, heh.

@dw817 Oof, I know exactly what that is. It's still adding stuff to the particle table, but I disabled the particle update function when you turn off particles, so they never get cleared. Let me fix that real quick.

P#72816 2020-02-06 09:06

Great work! I really like how the gameplay feels, and the graphics are very smooth.

Although, around like level 26 or so, the animations seemed to start stuttering or something? It's hard to explain. Or maybe it was like the smoothing was out of sync with where the piece actually was, like it would look like the piece was higher that it actually was, which made playing hard and I eventually succumbed to failure as a result.

P#72934 2020-02-09 16:02

@joseph3000 Well, I did encounter that problem while trying to work out the fall smoothing, so it's very possible my math was slightly wrong and falls apart at higher levels. Really, though, it's only supposed to go up to level 15, I just never implemented a cap of any kind, so I suppose you could consider it a kill screen? Regardless, if I ever get around to making a big update to the cart like I want to, I'll address stuff like that and likely add an infinite mode.

P#72944 2020-02-09 21:18

@Spaz48 I hope you get to update it! I really enjoyed it. I love Tetris. You have one of the best clones for PICO-8. Star for you!

P#72965 2020-02-10 15:21

Looks like you fixed the problem, @Spaz48. Nicely done.

This is definitely one of my favorite TETRIS games.

Gold star for you.

P#72980 2020-02-11 01:58 ( Edited 2020-02-11 01:59)

Really well done! You even implemented t-spins :D.

A lot of nice subtle animations like how pieces slide and tween left to right.

P#77100 2020-05-24 03:42

Great game, score is 190, but that only happened because I’m playing on an iPad and I accidentally pressed the up button, which is The insta-drop button

P#86255 2021-01-08 11:55

a trilha sonora é perfeita, a jogabilidade é perfeita, tudo nesse jogo é perfeito

P#86766 2021-01-25 12:42


Hands down best Tetris made with PICO-8 :)


P#87374 2021-02-08 04:58

I wish I would make a Pico 8 game like this one...

P#91866 2021-05-12 20:58



P#92791 2021-05-29 23:15

SRS kick table doesn't work with L and J when you tried to do perfect clear (0, -1)

P#96318 2021-08-21 15:34

Really like the soundtrack

P#97672 2021-09-22 18:57

10 out of 10

P#97673 2021-09-22 18:57

got the picture

P#97674 2021-09-22 18:58

Not a big deal but, maybe lines should be checked before overflow ;)

Very nice and smooth tetris, kudos !

P#97723 2021-09-23 19:50

why is this so dificult

P#100139 2021-11-15 00:51

it’s good

P#104449 2022-01-07 04:37

This is incredible! Love how it feels to play, and having all the different block pattern options is nice and fun.

P#113999 2022-07-06 00:45

i would be surprised if i could get t-spins

P#116733 2022-09-01 14:26

Anyone else hear the FNAF 2 song in the game over theme? Also good game btw, cool intro.

P#122459 2022-12-15 06:53

Great implementation :)

P#124011 2023-01-09 14:19

Now that I've actually started making my own games here, I realized that you're using more than 16 colors, how does that work?

P#130697 2023-06-09 03:19

This is probably one of the best runs I have ever had anyways, good job! This is one of my favorite games to play on this site alongside the likes of Celeste Classic.

P#138956 2023-12-21 03:28

this is the best titres i played in all my live

P#141294 2024-02-08 18:52

Really great version of not-tris :)
no seriously, good job!

P#141356 2024-02-09 22:15

When I try to play this on my Miyoo on the Pico-8 wrapper, it doesn't detect the button inputs to start the game. Weird.

P#147094 2024-04-22 06:40

Same for me. Miyoo Mini Plus + Pico-8 wrapper and none of the buttons work. Only game with this issue.
