A very simple game, but despite that it's been poorly implemented. Clicking on on part of a combination automatically chooses the other part, and there's no apparent* way to choose a different card. It also seems* impossible to make combinations containing more than two cards. This reduces the game to mindless clicking, as there are almost no real decisions to be made.

*"apparent" and "seems" because there is no actual instruction on how to physically make the plays. So maybe there's a way to do it, but I couldn't figure it out.
