Ra is an auction and set-collection game with an Ancient Egyptian theme. Each turn players are able to purchase lots of tiles with their bidding tiles (suns). Once a player has used up his or her suns, the other players continue until they do likewise, which may set up a situation with a single uncontested player bidding on tiles before the end of the round occurs. Tension builds because the round may end before all players have had a chance to win their three lots for the epoch!
