Featuring five asymmetric player mats and unique scoring conditions, each mat representing one of the five dinosaurs present in Sauros.

The game is played in a series of rounds. At the end of each round, the player mats are rotated. Once each player has played each mat, the points from all rounds are tallied and the player with the highest score wins.

In the game, a player leads a tile or set of tiles, and the other players must follow by either playing a higher tile or set of tiles as the set that was led or passing. The play continues until all players have passed in succession after the final play, and the player who won the last set leads next. Play continues until one player has played all of their tiles. Each player then pays chips to those players who performed better – that is, the player who went out will get paid by all other players, and the other players pay points to one another based on the difference in the number of tiles each held at the end of the hand. A game lasts five rounds, and the player at the end of the game with the most points wins.

Players are trying to collect huge sets – but only in three colors, as every color beyond the third will cost players points. Jokers are highly-prized, as they always match what players want, and +2 cards provide sure points, giving players a back-up plan if everything goes wrong in collecting colors.

Once only a few cards remain in the deck, the round ends and everyone tallies their score, choosing three colors of cards to score positively while any other colors counts negatively. Each color is scored using a triangular number system: the first card in a color is ±1 point, the second card is ±2 points, and so on. The player with the high score wins!
