Im not saying youll get cookies if you play this game, but Im also not not saying it.
This game is super simple. The piece in the center changes and you need to put it in one of four surrounding circles before it goes away. If you place it in a circle that already has that piece, you lose. Once you fill up a circle with all five pieces, the circle will clear.
I hope youre fast... and have nothing else to do... cause youll play it for hours. like... literal hours.
