Simplicity of play and complexity of possibilities combine to make an endlessly replayable puzzle. Like some of the better known puzzles in mobile, like threes!. Slick music and cute animals make the appeal even better.

I still haven't got the feel for the depth of the puzzle brought by the puzzle board size, but it feels like it should be grand.

I'm glad it taught me a new game. You could play an analog version of this with dominoes, a cat and a dog (they might not be as cooperative as in game, though).
