Battle for the Suns is a game for The Mystique Deck, in which 2–4 players make cumulative blind bids for suns. Each round, a card is revealed from a deck of suns, then each player secretly selects a card to bid for it. A card's bid value is its face value (1–5) + 1 for each attribute that matches the sun card. There are three turns of bid accumulation each round, after which whoever has the highest total bid takes the sun card; however, players can drop out after the first or second bid, leaving the sun to the last man standing.
