Each round in Yin Yang; a.k.a. Fifty-Fifty or Zen Master; players play a card from their hand. The highest card played on a turn receives light tokens; the lowest card dark; with the exact number of tokens determined by a scoring card revealed for that turn. Once the round ends; players eliminate pairs of light and dark tokens from their holdings; and their score for the round equals however many tokens remain. After a certain number of rounds; whoever has the lowest score wins.Yin Yang differs from its predecessor Relationship Tightrope in that only nine of the ten cards in hand are played each round — giving players some wiggle room when deciding what to play — and the scoring cards have differing numbers for the light and dark tokens received on a turn (whereas in the previous game the scoring cards were parallel — such as 9/9 or 8/8).
