Prism Blast 3D

Prism Blast 3D calls itself a radial block puzzle, and that is exactly what it is. The board is a disc divided into concentric rings and wedges, with a hole at the centre, glowing teal against a dark sea.

Three curved blocks wait in a tray below. Drag one onto the disc and it sticks where it lands. Fill a whole ring, or a whole wedge from the middle outward, and that line blasts away.

Level one spells out its target: reach two hundred and forty points in forty-eight turns, under the name Aurora. Every block you place uses a turn, and a second counter warns how long before junk closes in.

A hold slot sits in the corner for a block you are not ready to use, and six limited helpers run down the right edge, including undo, hammer, swap, shuffle and an hourglass. A hundred levels sit behind the first.
