I love pilgrammed

There are currently 7 main tiles excluding their variants (20 in total):

O and X

Combination of O and X that looks like this: ⦻

Toggle tile that can be toggled between O and X

Wall that acts like indestructible tile and doesn't allow any other tile to be placed on top

Only X and Only O tiles that basically let only O or X to be placed on top

Shield tile that permanently protects any tile placed on top

Junk tile can be removed at a cost of a turn

Also there is a huge menu dedicated just for customization of the game, such as:

how many tiles there has to be in a row for it to count

map generation

wall that surrounds whole map and can be expanded which forces players to play in one area

can player destroy other cells

and much much more

note: that this menu currently can only be accessed by editing source code in main.lua but you can edit map generations features and enable debug mode by pressing number keys (1-6 and 0)
