Earlier this year I got into Put Number. It's a terrific little point scoring puzzle app game.
Recently, I discovered Merged! which is very similar.
Which leads us to the sequel Put Number 2. It's very similar to the original Put Number. The difference is a 'stone' number that must be eliminated before you run out of room. The rules for eliminating the stone - I understand. The scoring with the stone - I'm not too sure.
