@electricblue thanks for the hint regarding colouring. Never would have thought of that and given up.

Interesting interaction with all the rules. I didn't expect to be coloring cells on a 2x2 but that was a fun surprise

Baffled why this is getting poorly rated. It’s a fun couple minutes, and it’s hard to have an idea come across in a 4x4 grid
