Another puzzle game with hexagon grid, but difficult! Player must fill the grid with different shapes. Each line and area must not contain same shape, just like classic Sudoku game!

You can find free PC version here:

the game is also on Steam if you are interested!

Steam app

EDIT: Formation 7 is unsolvable in this demo. Steam version has fixed this issue.

Formation 7 with 9 circles seems unsolvable to me. Please confirm.

Formation 7 is unsolvable. I fixed it on Steam but I didn’t update the demo.

Formation 9 is okay.

Thx for that fast reply. Played all other levels, was much fun. Cool idea.
