Sixis (2008)

A dice game from Asmadi Games.
Cards are dealt out, each having a specific requirement (such as roll two fives, roll 1-2-3, etc.) and worth a set number of points. Each turn you may roll your six dice and try to satisfy the requirement of a card--when you do, you may claim the card, or flip it over revealing a related but more difficult requirement that is worth many more points. Be careful, though, as your opponent may be the one to claim the more valuable card. In addition, each turn you may set aside any number of the results you obtained on your dice to work towards a card. Rolling six of a kind nets you a Sixis, ending the game.
