About this game
Prism Blast 3D is a fresh take on block puzzle — played on a round 3D board instead of the usual square grid. Drag blocks onto the rings, line them up to blast whole rings and spokes, and keep the creeping grey junk from closing in.
How to play
- 1Drag a block from the tray onto the round board.
- 2Fill a whole ring or spoke to clear it.
- 3Press a cell to aim, release to blast (tap outside to cancel).
- 4Grey junk creeps in from the outside — only a blast clears it.

Tips and strategy
- Only a blast clears the grey junk, so never leave a completed ring sitting there. Finishing it the moment it is ready pushes the creep back and buys you room to build the next one.
- You place what the tray gives you. Instead of forcing a block into the ring you had in mind, look for the ring or spoke that this exact block completes.
- Track the rings that are one cell short. Knowing which gaps you have makes the tray much less frustrating, because you already know whether the next block is any use to you.
- Aim is committed when you release, so choose the cell and check it before letting go. The tap outside the board is there for the shots you regret halfway through aiming.

Frequently asked questions
- How is Prism Blast 3D different from other block puzzles?
- The board is a set of concentric rings rather than a square grid, so lines run in two directions, around a ring and out along a spoke. Clearing either one blasts it away.
- Can I play Prism Blast 3D on a phone or tablet?
- Yes. You drag blocks from the tray with a finger and tap a cell to aim, with a tap outside the board to cancel, so touch works as well as a mouse does.
- What is the grey stuff on the board?
- Grey junk creeps in from the outside edge and fills the cells you need. Only a blast removes it, which is why finishing a ring early is about survival rather than tidiness.
