There's no boring wait for your turn in this game. All players are part of the chaotic frenzy to rid your cards by stacking them in numerical sequence - up or down - on the centre piles. The twist to this game is that numbers are depicted in five different ways: numerals, die faces, Spelled words, Roman numerals, and the number of fingers showing on a hand. Numbers are spelled out in English and Spanish, but not French, which posed an added challenge for our Francophone testers, as did the Roman numerals for kids who hadn't seen them before. A fun game, with just enough of a recognition challenge to add a little brain work, too.
