Ubongo Extreme (PL) is the successor to the successful Ubongo, but it is played at a higher difficulty level. As in Ubongo, all players place their blocks on the board simultaneously to complete the required shapes as quickly as possible. Time is measured with an hourglass, and whoever completes the task before the hourglass runs out shouts "Ubongo!" and then takes a gem from the bag. If there are two fastest players, they each take two gems. It is more challenging than the previous version of the game, as there are new, unusual hexagonal blocks. Nevertheless, the game is just as captivating and addictive as before. The winner of the game is the participant who collects the most valuable collection of gems.
