Helvetiq Zen Master Card Game, 8+ Years

Each round in 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.
