Card Flash

You get five piles of seven cards. After a random pause, a card flashes briefly — memorize it, then pick exactly two pile tops within five seconds. Your flash plus those two cards score together: pairs, suit matches, straights, flushes, and three of a kind stack (triple aces score big). Wrong hands and timeouts with fewer than two picks cost a heart. Survive all 17 flash cards or keep your three hearts.
