A puzzle of light on a grid.
One emitter fires a single white beam. Mirrors turn it ninety degrees, a prism
splits white into its channels, a splitter forks it, a filter ๐๏ธ subtracts colour.
Every target ๐ฏ demands an exact mix ๐ฅฃ - amber, magenta, cyan, or one of the blends.
You only ever change one thing: which way a mirror faces. Solve in as few flips
as you can.
WHAT IS INSIDE
โข 48 campaign boards across six sectors: Vela, Lyra, Ara, Pyxis, Norma, Crux.
Grids grow from 5x5 to 9x9 and new โจ pieces unlock ๐ as you travel โ๏ธ outward.
โข A daily board, the same one for everyone, with a streak ๐ฅ that remembers.
โข A workshop where you build ๐จ your own boards. The solver judges them while you
place pieces: solvable or not, the best possible move count, whether that
solution is unique, and how hard the board rates.
โข Poster studio: turn a solved board into a poster, recolour its beams from a
photo ๐ธ you take or pick, and save ๐พ the result to your gallery ๐ผ๏ธ.
โข An optics library ๐ that shows exactly how each piece behaves on a live board
you can touch.
โข Progress ๐ and archive: stars, par ratios, piece usage, and every board you
have solved drawn as a real thumbnail.
AN ENGINE, NOT A LOOKUP TABLE ๐
Every board is generated on your device ๐ฑ from a seed, then proved solvable by an
exhaustive solver before you ever see ๐ it. Par - the minimum number ๐ข of mirror
flips - is computed, never guessed. Hints come from that same solver: the next
flip on a genuinely shortest path, not a vague nudge.
NO CONNECTION NEEDED
The game ๐ฎ is completely offline ๐ด. No account, no sign-in, no purchases,
no tracking. Nothing about how you play โถ๏ธ leaves your phone ๐ฑ. The only screen that
loads anything from the internet is the privacy policy.
Three stars for a solve at par. Two if you come close. One for finishing at
all. Par is always reachable - the solver found it first.
Bend one beam of light with mirrors and prisms. Solve it in fewest moves.
