Nanobot Reactor

Push atoms. Build molecules.

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

NANOBOT REACTOR is a synthesis chamber, a blueprint, and a handful of loose atoms. Shove an atom and it slides until a wall, a fixture, or another atom stops it. Bring the right ones to rest side by side and the bond snaps into place. That click is the whole payoff, and it never gets old. HOW IT PLAYS Tap an atom to select it, and the lane it would travel lights up before you commit — you never have to guess where something will stop. Tap the lane to shove it. You are a nanobot on the floor of the chamber, so you have to be able to walk around to the pushing side first. That one restriction is what turns sliding into a puzzle. MOLECULES YOU ALREADY KNOW Water first, then the things that burn, the things you breathe, the ground you stand on, and finally what your DNA is strung together with. Seventeen molecules across seven chapters: water, carbon dioxide, ammonia, methane, silica, phosphate, phosphoric acid and more. HYDROLOGY — two elements. Everything alive starts here. COMBUSTION — carbon. The element that burns, and the one you are made of. THIN AIR — nitrogen. Four fifths of every breath you take. SILICATE — silicon. Sand, glass, and the ground under all of it. GENOME — phosphorus. What your bones and your DNA are built from. SYNTHESIS — molecules are things now. Build with them. REFINERY — everything you have learned, in one room at a time. REAL CHEMISTRY, HONESTLY LABELLED Every name, formula and bond in this reactor is real. The geometry is not: a square grid cannot hold water's 104.5 degree bend, so the molecules are drawn flat and stylised. The game says so on its first chapter card rather than burying it. THREE STARS MEANS OPTIMAL Every chamber ships with a par, and that par is not a designer's guess — a solver searches the whole chamber and proves the shortest solution before the level is allowed to ship. Match it for three stars. Nothing else is being measured: not speed, not streaks, not how many times you tried. 287 CHAMBERS A curve from two pushes to eleven. Every chamber is solvable, every par is optimal, and the whole optimal solution is replayed through the real game before it ships. Level h4-12 is the same chamber for everyone, forever. NO CLOCK. NO LIVES. NO MOVE LIMIT. Nothing is timed and nothing can be lost. Undo is unlimited and free, and so is restarting. The only way to be stuck is to have shoved an atom somewhere it cannot come back from, and that costs exactly one tap to fix. CALM BY DESIGN No timer, no lives, no streak to protect, no falling anything. Nothing on this board is in a hurry, and neither are you. Built for short sessions: the train, the line, one more chamber before bed. DESIGNED FOR ONE-HANDED PLAY Portrait only. Big tap targets. Handcrafted retro-neon art, with the six elements coloured so you can tell them apart at a glance, and configurable SFX and haptics. FULLY OFFLINE No accounts, no servers, no sign-in, no analytics. Play on a plane. Ads are non-personalized. REMOVE ADS A single one-time purchase permanently removes interstitial ads. No subscriptions, no currency, no shop, nothing to grind. The whole first chapter is ad-free either way. Made with care by Archivium Labs.
