Ubongo is a fast-paced, addictive, and easy-to-learn geometric puzzle game. Players race to piece together interlocking tiles so they fit perfectly on their puzzle boards. Here’s how it works: Each player receives a set of eight tiles. The tiles are polyominos — geometric shapes formed of equal-size squares joined edge to edge in different arrangements. At the start of each round, each player gets a new puzzle board. Each player must perfectly fill the blank space on the puzzle board with tiles. Once the first player has solved the puzzle, the player shouts “Ubongo!” and the countdown is on: The other players must solve the puzzle within the time limit, or they will not earn any points. All players who solve the puzzle get a point, and the fastest player also gets a bonus gem worth one point. After eight rounds, the player with the most points wins.
