GEMJI is a board game released in 2020 for 1–18 players, 1–120 minutes per game, and ages 4 and up. It was designed by Mark Ralev and its main mechanics are Race, Tile Placement, and Grid Movement.
The legend says that in the year 2349, an adventurous young man hacked into the head of a Gemji prince - the most secretive and thriving high-class caste, unveiling a very well-kept secret. He stumbled upon a mysterious board game they used to train their children. Once the hacker reconstructed the abstract game, he revealed an ingenious system for learning various life concepts. The people who played & learned through this framework became wiser, stronger, and more capable, helping the nation become the most powerful on Earth. Nowadays, this "game" is known simply as GEMJI. The hacker changed the future once, and now it's your turn. Game on! GEMJI is a modular game system made of 70 double-sided magnetic tiles that give you the freedom to play multiple games. Games include original titles developed by the GEMJI team, educational games, and popular classic game adaptations. Just like a standard deck of cards, the GEMJI System offers multiple games in one set. The big difference is that GEMJI could be used in many more situations and combinations, which means MORE games! The magnetic grid, the double-face tactile interface, the unique design language, and 3D build options make GEMJI unbeatable. Over 30 pre-made games exist currently, and more will continuously be added. —description from the designer
GEMJI supports 1–18 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 GEMJI is 1–120 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 GEMJI for ages 4 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.
GEMJI has a complexity rating of 2.7 out of 5 from BoardGameGeek players, which makes it a medium-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.
