Bounded Rationality Blues

Click Deal a board. Study the spaces, then click Go! when you're ready. The cards flip and a 30-second play clock starts — click a square to reveal its color again. The goal is to find all 18 blue squares in exactly 18 turns. Fall short of that and you score under 100. Hit it, and the time bonus unlocks: the less time you spent studying and playing, the higher your score climbs, up to a perfect 1000. Red spaces cost you a point; the black space ends the game.
