## What is PRISM?

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.

■ Nothing gets in your way

· No ads
· No in-app purchases
· No account, no sign-in
· No networking — the app never asks for internet access
· No data collected
· No lives, no energy, no timers
· No locked levels — stuck? just move on to the next one

You buy it once. That is the whole transaction.

■ 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.

### 5/5 — 게임이 너무 예쁘고 두뇌게임 좋아하시는 분들 강추합니다 !!

*2026-09-13*

와이파이가 필요 없어서 언제 어디서든 렉 없이 작동하는게 너무 좋은 것 같아요 ㅜㅜ 분열부터 슬슬 어려워져서 승부욕 생기고 재밌어지는 것 같아요 ㅋㅋㅋㅋ 다른 게임들은 게임 한 번 끝나거나 기회 다 쓰면 광고 나와서 하다가 지우게 되는데 이동 추천 횟수(?)는 있지만 실패했다고 광고가 나오지 않아서 거부감이 없네요 ㅎㅁㅎ 하면서 몰랐던 빛의 특성도 알게 돼서 학교 학습 시간에 써도 좋을 것 같은데요 ?!!

**Developer response:** 학교 학습 시간이라니, 그건 저도 생각 못 했습니다. 감사합니다.

말씀하신 "이동 추천 횟수"는 최소 탭 수예요. 추천이 아니라 그 판을 풀 수 있는
진짜 최솟값입니다. 240판 전부 기계로 다 돌려서 구한 값이라, 그 안에 풀면
레벨 목록에 ★이 남아요. 넘겨도 벌칙은 없습니다. 애초에 실패라는 게 없는
게임이라 광고 띄울 자리도 없었고요.

업데이트도 계속 하고 있습니다.

### 5/5 — 시간가는줄 몰라요

*2026-09-11*

너무 재밌어요 시간가는 줄 모르고 하고 있어요!! 스테이지 더 많이 만들어주세요!!!

**Developer response:** 시간 가는 줄 모르셨다니 다행입니다. 감사합니다.

스테이지는 지금 240판이에요. 혹시 다 보셨으면 레벨 목록에서 ★과 ●을 한번
봐주세요. ★은 최소 탭 수로 푼 판이고, 그거 채우는 건 사실상 한 바퀴 더 도는
겁니다. 더 만들어달라는 말씀은 적어두겠습니다.

### 5/5 — 재미있어요!!

*2026-09-10*

터치할 때마다 빛이 즉각적으로 반응해서 조작하는 손맛이 아주 좋습니다. 초반에는 꽤 쉬운 편인데 색깔이 갈라지는 구간부터 난이도가 올라가며 확 몰입하게 되네요.

한 번 구매하면 광고도 없고 스테이지도 많아서 한참 재밌게 할 수 있을거 같네요 ㅎㅎ

**Developer response:** 손맛을 알아봐 주셔서 반갑습니다. 감사합니다.

그 부분은 일부러 나눠놨어요. 조각은 부드럽게 돌지만 빛 계산은 0초입니다.
탭하는 순간 이미 새 길이에요. 색깔 갈라지는 구간이 3챕터 분산이고, 거기서부터
챕터마다 새 조각이 하나씩 붙습니다. 소리도 한번 켜보세요. 회전음 높이가
격자 위치를 따라가서 풀다 보면 멜로디가 됩니다.

## Version history (last 5 releases)

### 1.4 — 2026-09-22

The first time you earn Perfect, the game says what it is.

· Solving in the fewest taps is Perfect. It leaves a star on the level list, while a plain solve leaves a dot. That difference is now explained once, right where you earn it.
· Before, nothing said the two marks meant different things, so it was easy to play on without noticing Perfect existed at all.
· It appears once. After that it stays out of your way.

### 1.3 — 2026-09-15

The board now tells you when one tap is left to keep Perfect.

· While you play, "1 to Perfect" appears at the bottom. One more rotation and the par is still yours.
· Go past par and it reads "Perfect missed". Before, a number quietly changed color after the fact, so it was easy to finish a chapter without noticing Perfect existed at all.
· Nothing is ever lost. Keep solving, or hit restart and go for Perfect again.

### 1.2 — 2026-09-11

Added Japanese and Simplified Chinese, and rewrote the optics explanations so a child can read them.

· Four languages now: Korean, English, Japanese, Simplified Chinese (choose one in Settings).
· Each principle card shows a "before tap → after tap" pair, so you can see what one rotation changes without reading a word.
· Reflection, dispersion and mixing are explained with everyday things. "Throw a ball at a wall on a slant and it bounces away by the same amount. Light does exactly this on a mirror."
· At larger text sizes the principle card no longer runs off the screen.

### 1.1 — 2026-09-10

Improved accessibility so a slightly off-target tap still hits the right piece.

· A tap that misses a piece by a little now still rotates the nearest one.
· Crystal shape markers are bigger, making colors easier to tell apart without seeing color.
· Text size can now be set to normal, large, or extra large (in Settings).
· Turning on Reduce Motion cuts down screen transitions and effects.
· Fixed the half-silvered mirror in the optics card to match how it looks on the board.

### 1.0.1 — 2026-09-10

It is now clear what to do from the very first screen.

· The crystals you need to light stand out, and the number still unlit is shown at the bottom.
· The first three levels have been rebuilt to be gentler. Level 1 takes a single tap.
· The first chapter's card now opens with the goal of the game, not the optics.
· The half-silvered mirror is drawn as a plate light passes through, so it no longer reads as a plain mirror.
· Fixed the tap counter showing through the Next button after solving a puzzle.
