Prism

A trick-taking card game played with a 52-card deck in seven color strands numbered 2-7 and three types of wild card named INFRA-RED, ULTRAVIOLET, and SPECTRUM. One color strand is used per player. Players are dealt 7 cards with a 3 card blind, and then take turns bidding based on how many tricks they think they can win. Highest bidder gets the blind and must win as many tricks as he bid. The highest bidder gains or loses points according to a formula based on whether he won his bid. Other players can also score points for winning tricks. First player to 100 points wins.
