by ahnt - Jam Entry

Ever wondered where the completed lines in Tetris go? What happens with them beneath the surface? Or where do the tiles come from?

Sirtet is showing you what happens beneath the surface of Tetris. Your mission is to take the completed lines or parts of them and turn them back into tetrominos. Connect four tiles of the same color to get a huge bonus, or connect lots of tiles with the same color to free space.

Use <left> and <right> to shift the dropping line around - the left and right wall wrap!
Use <down> to make lines drop faster, or use <up> or <space> to immediately drop a line to the floor.

I love the idea that there is a person playing a game of reverse Tetris in order for other people to play Tetris.
Great idea.

A great idea, and an interesting twist on both Tetris and the theme. Awesome idea! I did spend several minutes confused though because I was trying to use WASD instead of the arrow keys.

Awesome, reverse Tetris :) I've played tons of different Tetris clones, but this one brought something new. Good job!

Hehee, awesome entry. I've always pondered the same... Controls were responsive, nice art, nice idea. Well done.

A nice demake, as well as fulfilling the current theme. The only doubts I have are the backgrounds – the Kremlin, some awfully-scaled gears and a cave?

Ouch my tetris hand! (similar to tennis elbow)
Great game!

What a great idea.

I would love to see a two player variant of this where one player is playing Tetris and the other person is making pieces to send them.

First i was like "ok, how the heck is this meeting the theme"...but then...very clever :D

This is brilliant. I could only think about how the other guy was wondering where is long straight piece was...

Interesting use of the theme, and unique game concept overall. I really liked the idea of reversed Tetris.

One of the best uses of theme I've seen. Very awesome core idea, tight implementation, and appropriate graphics/audio. You did a great job, and I expect good results from the voting out of this one. :D

That's an amazing good idea you guys had!

Very nice :) has a very zen feel to it, I got totally lost playing it for a bit longer than intended haha. It seems odd that sometimes you can make a shape out of certain colors but have extra blocks of that color also disappear, wasn't sure if it was intentional but I loved it either way :)

This is great! Love the idea.
Also, congrats on successfully reversing the gameplay while still keeping the feeling of the original game.
Would be interesting to see this connected to actual games of tetris...

Brilliant game, you should know right now that as far as I'm concerned you should win best innovation for LD29.

Very original idea. Fun, simple, and a complete game.

IMPORTANT NOTE: If you want to place in the final results, you NEED votes. The easiest way to get votes is by rating other games. Judging lasts for 3 weeks following the end of Ludum Dare. For best effect, rate 20 games as soon as possible. Rating more games is encouraged.


TEAMS: Teams entering the Jam should pick a single representative to submit your game, or create a team specific account you can share. We currently do not support Team Voting, but sharing an account and together playing and rating games is acceptable.

NOT LOGGED IN?: If you get a message about not being logged in, even though you are, it’s because your web browser cached the non-logged in page. You can fix this by either refreshing your cache or clearing your cache. CTRL+F5 in many browsers. Chrome is a bit more work. Press F12 to enable Developer Mode, then you can right click on the refresh button and select “Empty Cache and Hard Reload”. This option is unavailable if you are not in Developer Mode.

PORTS: Ports to other platforms can be done after the deadline. That said, the sooner you finish your port, the sooner people can play your game, improving your chances of placing in the final results. For best results, provide a Web version of your game, or a Windows version with no dependencies. Also be sure to rate about 20 games to improve your visibility.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs ( and you will show up.

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crash or win condition bugs after the deadline (in a sense, like “porting” to support more players). We also allow “typo” bugs. I.e. A true that should have been a false, a word that should have been a different word, very tiny changes that you would have caught if you had more sleep. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just things you messed up last minute. Typos.
