Tides of Time is a drafting game for two players. Each game consists of three rounds in which players draft cards from their hands to build their kingdom. Each card is one of five suits and also has a scoring objective.
After all cards have been drafted for the round, players total their points based on the suits of cards they collected and the scoring objectives on each card, then they record their score. Each round, the players each select one card to leave in their kingdom as a "relic of the past" to help them in later rounds. After three rounds, the player with the the most prosperous kingdom wins.
Tides of Madness adds a new twist to the above game: madness. Some cards, while powerful, harm your psyche, so you must keep an eye on your madness level or else risk losing the game early as your mind is lost to the power of the ancients. More specifically, eight of the eighteen cards in the game feature a madness icon, and while scoring, you receive a madness token for each such icon in your collection of cards. Whoever has the most madness in a round either scores 4 points or discards 1 madness token — and the latter option is valuable because if you ever have nine or more madness, you lose the game immediately.
