In Ubongo Junior 3-D, all players compete simultaneously to cover their playing area as quickly as possible with the 3D building blocks. No box can be left uncovered, and nothing can be placed beyond the edges. Once this has been done, race to build the tallest possible jungle tower. After 90 seconds, time is up! Now everyone measures their tower with the giraffe to see how many precious stones they get. Who can collect the most gems?
