Prismo

Build the light. Drag glass onto the board and bend a single beam until every target burns in exactly the colour it asks for. Mirrors turn the light. Splitters send it two ways. Filters strip it to one colour. Prisms break white into red, green and blue. A spectrum shifter cycles the channels without moving the beam at all. The light re-traces live under your finger, so you see the consequence before you let go. 1,125 LEVELS THAT ALWAYS HAVE AN ANSWER Forty-five worlds, each with its own planet and its own focus. Every level is built backwards from a working light path and then replayed through the simulator before it ever reaches you, so an unsolvable puzzle does not exist here. POLARIZED GATES From world 41, boards carry fixed cells that light may only cross along one axis. A gate never blocks the solution โ it rules out every wrong route through that cell, which turns a big board from a search into a deduction. ARCADE Three lives, a clock that tightens the longer you last, and endlessly generated boards that get harder with your streak. One number to beat. A DAILY PUZZLE The same board for everyone, every day. No hints, and a streak to keep. NO STRINGS No ads. No in-app purchases. No account, no tracking, no network of any kind. The game is yours on a plane and in a tunnel. Everything in the shop is bought with Prismacoins you earn by playing. MADE TO BE PLAYABLE Colour-blind markers put a distinct shape on every red, green and blue channel. Reduce Motion is honoured throughout. Eleven languages, switchable inside the app without touching your device settings.
