In this chilly challenge, players flip over cards one at a time, revealing surprisingly similar sea life. When players spot creatures that match they race to slap them—whoever slaps first collects the cards. But more often than not multiple players will slap multiple cards and there may be more matches than hands, so everyone is involved on every turn. It's fast, fun, and totally . . . cool. The sturdy tin is great for throwing in a purse or backpack.
