Prism Blast 3D

Drag a block from the tray onto the round board. Fill a whole ring or spoke to clear it. Press a cell to aim, release to blast (tap outside to cancel). Grey junk creeps in from the outside — only a blast clears it. Use the power-ups below the board: ↩ Undo, ? Refresh tray, ? Swap, ⏳ +5 Turns, ? Hammer (tap a cell to smash). Don't run out of room to place the next block.
