TriATri is a board game released in 2021 for 2–4 players, 20–30 minutes per game, and ages 10 and up. It was designed by OR-U (おるー) and its main mechanics are Trick-taking.
TriATri is a must-follow trick-taking game in which the players each aim to score the most points. The "lead suit" is determined by the color of gem chosen by the lead player, from either in front of themselves or a central pool. The winner of the trick will take the gem. Players earn positive points for complete sets of gems (1 of each color), and will typically lose points for incomplete sets. The cards have a relationship such that their value may be multiplied depending upon the color of the previously played card.

TriATri supports 2–4 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for TriATri is 20–30 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists TriATri for ages 10 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
TriATri has a complexity rating of 2.0 out of 5 from BoardGameGeek players, which makes it a medium-light game.
