- Work backwards from the goal. Ask what the final state has to look like, then ask what the state before that must be.
- Read the whole board before your first move. In most puzzle games the first move is the most important one, and it deserves ten seconds of looking.
- Because this is a Girls game, take your time with creative choices; there is rarely a wrong answer in this kind of game.
