The small Mitbringspiel makes a lot of fun, and even the future win with us on educational value because not only fast construction, but also simple to add is in demand. In Mitbringspiel actually the cube serves as a timer. The roll will have to add together until the sum is reached 15. Once the time comes to an end, belongs to the builders at the building. Because our 4-year-old son is not yet in a position a "timer" to be we added to our game an hour glass, and thus build only after time. Later it is determined even funnier when clock geschriehn be out during the construction of the status of the cube. I highly recommend this game.
