Jester Prism app iconJESTER PRISM

Coming to iOS

White light in.
Every colour out.

The wizard casts white light into the chamber. Every crystal it crosses takes something away — a ruby passes only red, a citrine only red and green. Slide the stones until every orb receives the exact colour it is asking for.

Colour can only narrow

Light is the piece you move.

You never move the beam directly. You move the stones it passes through, and the light does the rest.

  1. Slide a crystal

    Drag a stone into open space, horizontally or vertically. Stones slide but never rotate, and a whole block moves as one piece.

  2. Filter the beam

    A crystal keeps only the colours it and the beam have in common. A ruby passes red, a citrine red and green, a diamond everything, an obsidian nothing. Colour can narrow but never widen, so a beam that meets two stones with nothing in common goes out.

  3. Bend and split it

    Prisms turn the beam ninety degrees. Splitters throw it both ways at once, and two beams arriving at the same orb add together — red and green make yellow.

  4. Match every orb

    Each orb shows the colour it wants as a ring and the colour it is getting at its centre. Match all of them inside the move budget. Solve within the target to earn three stars.

From glimmer to white crown

Room to grow.
More to bend.

Start with short, single-beam chambers, then meet prisms, splitters and boards that need light routed two ways at once. Later regions ask for longer solutions and tighter budgets.

Every chamber is generated with a verified shortest solution, and that solution is what sets its par. Replay a chamber and its layout stays the same.

A puzzle in your pocket

Play at your own pace.

No account required. Chambers work offline, progress stays on your device, and an unfinished attempt is waiting when you come back. Five guided lessons teach the rules without spending anything.

The game includes ads. Restarting a chamber is always free, and an optional rewarded video can add three moves once per attempt or replace a spent booster.
