Read 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.

Rings turn one notch per tap. A dot can hop to the next ring only at the exact moment two rings kiss. Land every dot in its socket in the fewest moves. Free to try: Orbits 1 and 2 (40 levels) and today’s daily puzzle, forever. One $4.99 purchase unlocks Orbits 3 to 6 (80 more levels) and the daily archive. No ads, no timers, no subscription. ONE RULE, EXACT Tap anywhere and every ring clicks round by its own spin: +1, −1, +2, or not at all. Tap a dot while it sits at a kiss and it arcs across to the touching ring. That is the whole game. Nothing is random inside a level and nothing is timed, so every board is a small piece of clockwork you can read before you touch it. THE CLICK OF GEARS MESHING The feeling you chase is the socket swinging into the kiss as the dot arrives. Every tick, hop and dock has its own sound, haptic and light: the notch marks blink in sequence, the hop leaves a luminous trail, the socket blooms, and a solved level ends on one calm chord. 120 LEVELS IN SIX ORBITS Every level was generated and proved by a solver, so par is the true minimum and a level is never unsolvable, only over par. Each orbit adds one twist: • Kiss – two rings, one dot, one socket. Learn the hop. • Wall – a stop bar rides the ring and refuses a landing. • Flip – a marked notch sends its ring the other way. • Three – a third dot, and three colours to route at once. • Still – rings that do not turn, and mixed spins. • Tangent – everything, on twelve-notch rings. Level 15 of every orbit plays differently from level 1. Three stars means par. Undo is free and unlimited, restart is free, and one hint per level shows the solver’s next move. ONE DAILY, ONE STREAK A new puzzle every day, built on your phone from the date, the same for everyone. Par is shown before you start. Solve it and your streak grows; share the result as text, not a screenshot. Reminders are optional and only offered after your first daily. MADE TO BE READ Every dot and socket carries a shape as well as a colour, so no rule depends on colour alone. Reduce Motion turns every pulse and burst into a fade. VoiceOver and Dynamic Type are supported throughout. Sessions are two to five minutes, one-handed, and every move is saved, so you can put the phone down mid-level and pick up exactly where you were. WHAT’S INCLUDED • Game Center: leaderboards for total stars and best streak, seven achievements. • iCloud: your progress follows you to a new phone. • No account, no ads, no in-app currency, no lives. • Anonymous usage statistics can be switched off in Settings. WHAT THE UNLOCK BUYS Orbits 1 and 2 are a complete small game and stay free. TANGENT Full Game ($4.99, once) opens Orbits 3, 4, 5 and 6 and the daily archive of the past 30 days. Restore Purchases is on the Unlock screen and in Settings. Privacy Policy: https://tangent.devera.app/privacy/ Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
