This is a test with minesweeper.
The changes over what an irregular grid brings is that cells don't all have 8 neighbors. Some can have less, some can have more. Therefore before uncovering a tile, you have to pay closer attention at the number clues and which tiles neighbors it.
So my intention is to make a very classic game a bit more challenging & fun.
I'm also prototyping with checkers/draughts, and plan to test similar variants for chess, othello and go.
