From the developer:
Sumaru is an exciting puzzle game that will challenge you again and again. In Sumaru you have three discs of 8 balls and an empty space in the middle. You must move the balls so that each of the 8 columns of balls (outer disc to inner disc) adds up to the number in the upper right. The inner two discs are rotatable.
