In VENNGRAM, you must find the right way to move, join, and intersect circles, in order to satisfy the requirements for each one of the 18 handcrafted levels available.

How to Play

  • Drag the circle over the targets of corresponding color to activate them.
  • If two circles meet, their color will mix. This can activate targets of both colors.
  • If two circles of the same color meet, they will cancel each other out.
  • The square target will only activate when not covered by any color.
  • The triangular target will only activate when covered by a single color.

I liked the graphics on this puzzle game and the fun puzzles.

Great puzzle game, but on level 14, how do I get the two green circles and the two yellow circles to activate the small circle targets, and the small triangular targets? Because whatever I do, one or more of the targets I activated with the circles I used would deactivate.

A small tip: in one of the solutions, the two outermost green triangles do not fall under any of the yellow areas. Remember that the position of the targets might mislead you! Thank you for playing!

Hmm, I couldn’t get this game to work on either Firefox nor GNOME Web (Safari) until I opened it up in a clean Firefox profile, otherwise I get “Play this game at”. Does this game require cross-domain cookies to play for some reason?

Anyway, finished the game! Difficulty increase feels quite unbalanced, but otherwise neat!

You need to make a sequel!

Nice game!!!

Two solid circles

This was a wonderful game! Thank you!

Nice 10 minute puzzle.


Really great concept. Fun, intuitive, but challenging gameplay. Never feels unfair. Dream features would be level reset (saves a click from leaving/returning), and a gallery showing my working solutions, as I currently can't really appreciate the Venn Diagrams.

I agree with you, also the level reset features seems to have been added.

I wonder if we'll get video walkthroughs of this game.

cool relaxing music and with simple commands and gameplay and challenging enough to really enjoy this game. Bravo !

Thank you, I'm happy you liked it!

the most unexpected part of this was how good the sound design was?!?! i was really jamming with the sfx above the music, that's some intricate systems!

Thanks, I'm glad you enjoyed it!

i just played Tower Join too and the sounds there are so good also omg. Where do you get these sounds, do you record them yourself? Amazing work

Thank you! I usually look for CC0 loops and samples, mostly at and, then I remix them in Audacity to match the theme or the feel I want for the game.

i see,  thank you!

Game doesnt load, Chrome

That's strange... What OS and which version of Chrome are you using?

Chrome 83 on Windows 7

I'm not sure what could be causing this issue... Using a test tool, the game loaded correctly on Chrome 83 under Windows 7. Perhaps, there is some temporary issue related to servers, or your network in particular, so please make sure to check again later.

I have this problem as well when starting from the itch-launcher. Halts with the progress bar at about 95%.

I had the same problem with the itch launcher, opening it in chrome worked though
