StringFusor
Read full descriptionHide full description
Strings of colored energy fall into a reactor. Fuse them into patterns and release what they hold. StringFusor is a color-matching puzzle in the classic falling-piece family, rebuilt around one idea: patterns you can AIM for. Beyond rows and columns lies a book of named fusion patterns — THE BLOCK, THE ZIGZAG, THE X — each with a measured difficulty and a real payout. You are never matching by accident; you are hunting a shape you chose. TWO WAYS TO PLAY EXPERIMENT is the self-directed game. Choose your target pattern, set your own dials — how many colors, how long the strings — and the reactor pays you for difficulty honestly: harder hunts, bigger energy. When you outgrow the pattern book, the forge offers shapes designed by the game itself — symmetric, provably buildable, and never seen before. Skip what you like; the chooser is never a dead end. PROGRESSION is the shared game. Every day, one board, one seed, one bonus target — identical for every player on Earth. Same strings, same order, pure play. Your best lands on that day's leaderboard, and tomorrow is a fresh start for everyone at once. New here? A short optional ORIENTATION teaches the six easiest patterns on a fixed board, and its own leaderboard ranks your cleanest run. BUILT CALM ON PURPOSE No timers — think as long as you want. Unlimited undo — every move can come back. No ads, ever. Nothing pulses, nags, or flashes at you: the reactor hums, the planet turns, the strings fall when you say so. Every button carries a small accessibility feature: a tap filter tuned to the frequency of a resting hand tremor, so an unsteady hand registers one clean press — designed in from the start, not bolted on. REPLAY any run move by move. Watch the DEMO play itself when you would rather study than fuse. Compete on Game Center, or never sign in at all. ONE HONEST PRICE All of PROGRESSION — the daily board, the orientation, replays, and its leaderboard — is free, forever. A single one-time unlock opens the full EXPERIMENT track: the dials, the pattern chooser, the forge, and its leaderboard. No subscription. No ads. No consumables. Try EXPERIMENT free once per day before deciding. GIVING 2.5% of the net profit from halfmarble's software will go directly to support Team Fox, the grassroots fundraising program of The Michael J.
