Prismwick

Prismwick is a calm logic puzzle about light. Sources send beams of red, green, blue or white light across a small glass board. Tap mirrors to flip them and prisms to turn them, and guide the light so that every crystal glows in exactly the color it asks for. Colors mix like real light: red and green make yellow, green and blue make cyan, all three make white. Too much light is as wrong as too little: a crystal that catches a color it does not want cracks, and that beam has to go somewhere else. HOW IT PLAYS - Tap a mirror to flip it, tap a prism to turn it 90 degrees - A prism splits white light: red turns left, green goes straight, blue turns right - Filters let only their own color through, walls stop light, pinned pieces stay put - Undo as far back as you like, or reset a level at any time - Three stars for solving in the fewest possible moves FOUR PACKS, 200 LEVELS Dawn - 40 levels on 5x5 boards: mirrors only, a gentle start Spectrum - 40 levels on 6x6: prisms and color mixing Filters - 60 levels on 7x7: filters and fixed pieces (Pro) Eclipse - 60 levels on 8x8 and 9x9: everything at once (Pro) Every level is checked by the game's own solver: it can always be solved, it is never solved at the start, and the move target shown on screen is the true minimum. Difficulty rises steadily through each pack. DAILY BEAM A fresh 6x6 board every day, the same for everyone and free forever. The calendar keeps track of the days you solved and of your streak.
