Sen is a board game released in 2017 for 2–5 players, 30–60 minutes per game, and ages 10 and up. Its main mechanics are Hand Management and Memory.
In Sen (English: "Dream"), the goal is to minimize the total value of your cards; however, you don't know what all your cards are at the beginning of the game. By using certain cards to peek at your own or opponent's cards, or swap cards with your opponent, you can try to minimize the value of your cards. When you think you have the lowest value, you can call end the round. If your value is not the lowest you receive a penalty. Rounds repeat until someone has scored 100 points, at which point the player with the fewest points wins. A game in the Golf family, it combines elements from Rat-a-Tat Cat and Cabo.
Sen supports 2–5 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 Sen is 30–60 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 Sen 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.
Sen has a complexity rating of 1.2 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
