The bowl has a hollow sphere (1) with transparent walls. The inner wall has geometric projections (5) regularly distributed to ensure rotation of dice. The dice are marked with digits, and represent units, tens, hundreds or thousands. A cylindrical base ring is shaped to receive the dice after rotation of the sphere, the dice settling into the periphery of the cylinder so they can be read. The top of the sphere is transparent and is formed into a lens to facilitate reading of the dice in the cylinder at the bottom of the sphere. The sphere is formed from two hemispheres that are fused together after the dice have been placed inside.
