## What is PRISM?

Rotate a mirror. A new path of light appears.
Guide the beam through every gem, then into the exit.
There is always exactly one answer.

PRISM is a quiet logic puzzle built from just light and mirrors.
A laser fires across the board, and rotating mirrors stand in its way.
Turn each mirror to "/" or "\" to route the beam so it passes through
every gem, then finally reaches the exit. No luck, ever. Every board
has a single solution, and pure logic will always get you there.

Start gentle, then climb. On Hard and Expert, wrong angles stay
plausible for several moves before they fail — so you have to read
the whole board, not just the next step. That is where the real
satisfaction lives.

FEATURES
- One-tap simplicity: rotate mirrors, that's the whole control.
- Always exactly one solution — reasoning, not guessing.
- Four difficulties (8x8 / 9x9 / 10x10 / 11x11), from first steps to brutal.
- A daily puzzle and a solving streak to keep the habit.
- Fully offline — play anywhere, no signal needed.
- No account, no sign-up, no personal details.
- A calm, minimal board where the light lines up beautifully.
- English and Japanese.

GREAT FOR
- Turning a commute or a coffee break into quiet focus.
- Fans of Sudoku-style puzzles that reward logic, not luck.
- Anyone who wants to think without ads breaking the flow.
- People who like understated, minimal design.
- A gentle "one puzzle before bed" ritual.

PRIVACY & PEACE OF MIND
PRISM keeps your progress — solves, streaks, times — entirely on your
device. Nothing is sent to a server. No account or login is required,
and we never ask for personal information. Everything works offline.
(An advertising SDK may process minimal data to show ads; personalized
ads are turned off.)
