|smithhemb||7||5||Yes || This is a speed game in which players race to identify and then slap the last card in a sequence. The sequence is set in motion by the center card whose markings tell you what you should be looking for (e.g. the card whose green number is smaller than the green numbers on all the other cards). Once you find the second card, it tells you what you're looking for in the third card (always highest/lowest number of a particular color), etc.
The round ends as soon as a player slaps a card. Everyone determines if that card should actually be the last card. If it is, then the slapper gets a card; if it isn't, the slapper loses a card. Game ends when one player has a predetermined number of cards.
This is a cheap, fun, portable game that is fairly customizable (both wrt length (number of cards needed to win) and difficulty (how many cards in a sequence). It's also playable as a solitaire and it reinforces number recognition and greater than/less than concepts for preschool kids. (It can be a very good kindergarten classroom game for kids who are just learning double digit numbers.)
The crucial determinant of whether this game works is whether all the players are roughly equally good (or bad!) at performing this kind of mental stunt. Age isn't an inherent advantage (that is, once you're old enough that you don't have to think much about which 1 or 2 digit number is greater than the other); kids can be quicker than adults.
