Dim A board of frosted glass tiles glows cyan and magenta against the dark. Touch one and it flips together with its neighbours, so a single tap can light a small cross of tiles or put it out. The aim on every board is easy to say and slow to master: leave the whole grid unlit. Soft The campaign holds thirty levels in five sets of six. The opening set starts on a 4×4 grid, Prism Row and Night Grid widen the field, Slant Light toggles the diagonal neighbours instead of the cross, and Deep Lattice closes on 7×7. Every board has a solution, and its par is the true minimum number of moves. Bright Match par and three stars light up beside the level, with 90 to gather across the campaign. Undo takes back a slip, and a hint lends a hand when a pattern refuses to give way. Flux Rush starts a 90-second clock and an endless stream of boards: each clear adds four seconds and points, with extra for solving on par, and a history table keeps your last twenty runs with the highest score marked. Brilliant Between boards, the Spectrum quiz draws ten questions from 24 facts about light, from ultraviolet to the first laser, each with a 15-second ring timer and a short note after the answer. A wheel menu turns under one finger, a stats page counts boards cleared and every toggle, and 13 badges wait to glow. Everything plays offline, with no ads and no account.
