Works on a plane, works underground, works forever.
Tap, and the light bends.
PRISM is a puzzle with exactly one rule. Tap a piece and it turns 90 degrees;
the light instantly finds a new path. Light every crystal with precisely the
color it asks for, all at once, and the board is solved.
The controls need no explanation — one tap is all there is.
If you want to know how light actually works, that is in here too.
■ Six chapters, 240 puzzles
I. Reflect — mirrors turn light by 90 degrees
II. Split — a half-silvered mirror passes light and reflects it at once
III. Disperse — a prism breaks white light into red, green and blue
IV. Mix — two beams meeting at one crystal become a new color
V. Refine — filters keep only what you want. Overshoot and you fail
VI. Converge — everything you have learned, on one board
■ Every puzzle has exactly one answer
All 240 levels were machine-proven to have precisely one solution before
shipping. No configuration works by accident, and no piece is decoration —
rotate any of them and the solution breaks. The par shown on each level is
not an estimate either; it is the true minimum, found by exhaustive search.

■ This is real optics
The angle of reflection, dispersion through a prism, additive color mixing,
selective absorption in a filter — every rule in this game comes from real
physics. Entering a new chapter shows you the principle behind it on a single
card. Tap once to dismiss it, or read them all later under "How light works".
It also states plainly where the game simplifies the physics.
■ If color is hard for you to tell apart
Every crystal carries its required color as a shape as well.
Red is a triangle, green is a square, blue is a circle. A yellow crystal
shows a triangle and a square side by side. You can finish every puzzle
in this game without seeing color at all.
■ About the sound
The pitch of each rotation depends on where the piece sits on the grid —
higher toward the top, lower toward the bottom. Solving a puzzle turns your
hand into a short melody. It only uses a pentatonic scale, so no order of
taps can sound wrong.
Turn the sound off and haptics take over the same job.
■ It is light
Nothing you see or hear was authored as a file. Apart from the app icon there
are no images and no audio inside; every beam of light and every note is
computed as you play. All 240 puzzles compress to 9 KB of data.
