Euclio is a snappy combination of card drafting and worker placement where players vie to earn the most trophies by claiming and manipulating various scoring boards, but beware! Only players with scoring markers on each board will gain its payout, but that won't stop the other players from using cards that alter it! Euclio is played over three game rounds that involve drafting cards, playing them to manipulate the boards and claim scoring opportunities, and finally scoring the boards themselves. Players can enter into pseudo alliances with players who share their scoring boards, while other players may play (or withhold) cards that hamper your plans. By only using a subset of the scoring boards, every game will be different as the boards determine what suit cards are in play with varying effects. Even among the same boards, their arrangement changes scoring timings for even more strategic variety! Simple rules make game-play itself very straightforward: on your turn either play a card face up for its effect, or face down to lay claim with a scoring marker. It's important to set your scoring markers on the most lucrative spaces before they run out of room, but doing so reduces your control, as without unused scoring markers, you must play cards face up for their effects, even if they help your opponents, and the earlier you commit your scoring markers, the less certain you can be about the final state of each scoring board. —description from the designer
