Made for the GMTK 2019 Game Jam, this game is a puzzle game where you only have one shape available to fill the whole level. The game featurs 34 handcrafted levels, each level with it's own unique tile shape.

The controls are explained in the game, but here they are again just in case:

  • Left Mouse Button: Place tile
  • Right Mouse Button: Remove tile
  • Tab or Space: Rotate Tile
  • You can skip already completed levels using the buttons in the bottom corners.

Thank you for playing!

Levels 21 and 28 are very difficult.  I like the concept and the execution is flawless.  Perfect puzzle game!

Hello MimmoO,

My name is Antonia Gates, I manage the games at I really enjoyed One Tile Only and I think it would be a great fit on our site!

I'm writing to ask if the game is available for non-exclusive licensing. Our licenses are totally non-exclusive, so you would maintain all of the IP rights and could continue to develop and distribute the game however you'd like to.

Please let me know if it is available, and how much it would cost. I'm looking forward to discussing this with you soon!

Best regards,

Antonia Gates

Really fun! I really enjoyed this game. All the levels after 34 got kind of repetitive though.


Thank you :)

Man there sure were a lot of levels! I found level 21 and 26 to be quite difficult and ultimately wasn't able to solve level 27. I wish there was some sound and music though.

Awesome, level 29 is destructive!!


Amazing game and great graphics and very addictive and fun and very nice 

This is a great game! When I saw the idea I thought it couldn't get harder, but it was very challenging. Also in the hard levels I was surprised to see that I need to think and plan the placement of parts, not only to place them randomly and hope to succeed. The amount of levels is also really impressive!

very nice! got to 3xbi and couldn't work out how to proceed, but really good stuff. could do with a reset button so you don't have to switch between levels when you want to clear the board and start over, but that's pretty minor.

Cool game, looks really polished

Can someone tell me how to beat 3XBJ?

Awesome game, really cool implementation fo the game jam theme I can easily picture this on app store as well. A bit of sound design is all it's missing. Hope you make into Mark's video!

Cool concept, and polished execution! Although shame there's no sound design. 

So nice! You need to make it to GMTKs video! :) Rooting for you!

Thanks :) I really hope i make it as well^^

A fantastic puzzle game. I really like it and I usually lose my patience quite quick when it comes to puzzle games. (I hate Sudoku) But that one has a great concept, calming visuals and is really fun to spend some time with. Great job :)


Thanks a lot for the kind words. The visuals were inspired by the puzzle game named "UpLeftOut". I can also recommend the other games from the same author (available for really cheap on steam).

Amazing game! Really addicting and fun! Loved the added messages on each level, really made you aware how well thought out the game was, and the tiles snapping into place feels very satisfying!

I thought I'd play it for couple of minutes but game grabbed me and didn't let go until I beat it <)

LOVE THIS! Super satisfying!  

Very satisfying when you finally beat each level.


Awesome puzzle game!The first few level feels like a satisfying tetris (similar shape) . But with the diagonal blocks, things start to get abit tricky

Love the snappy feel and the satisfaction of the level completing by itself near the end.

Yes the diagonal blocks definitely add to the challenge. And one could go on and on and create new tiles. Completely disconnected tiles (Like the Arrow one) are super interesting, since they lock together differently than normal pieces.

Muy entretenido, me sorprendió bastante y la suavidad en las animaciones, se sienten muy bien c:

Gracias! Uso Unity y el complemento DoTween para escribir animaciones directamente en el código.
