Degana has released Ponere 1.0, a new puzzle game for the Mac platform, in which players arrange tiles to create closed rings, such as a circle or oval. Tiles are arranged using controls that move an entire column or row on the game board--so moving pieces usually involves moving more than one at once. Ponere includes 60 levels.
