Nanobot Reactor
Push atoms. Build molecules.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Shove an atom. It slides until something stops it. Now build water.
NANOBOT REACTOR is a synthesis chamber, a blueprint, and a handful of loose atoms. Slide the right ones together and the bond snaps into place — a click that never gets old.
HOW IT PLAYS
Tap an atom and its lane lights up before you commit, so you always know where it will stop. The catch: you're a nanobot on the chamber floor, and you have to walk around to the pushing side first. That one rule turns sliding into a puzzle.
MOLECULES YOU ACTUALLY KNOW
Water first. Then the things that burn, the air you breathe, the ground you stand on, and what your DNA is strung together with. Seventeen real molecules across seven chapters — real names, real formulas, real bonds. The geometry is stylised, and the game says so up front.
287 CHAMBERS
A curve from two pushes to eleven. Every chamber is proven solvable, and every par is the true optimum — a solver searches the whole chamber before the level ships. Match it for three stars. Nothing else is measured.
NO CLOCK. NO LIVES. NO MOVE LIMIT.
Undo is unlimited and free, and so is restarting. The worst mistake costs exactly one tap to fix.
CALM BY DESIGN
Nothing in this chamber is in a hurry, and neither are you. The train, the line, one more molecule before bed.
DESIGNED FOR ONE-HANDED PLAY
Portrait only. Big tap targets. Handcrafted retro-neon art, with the six elements colored to tell apart at a glance.
FULLY OFFLINE
No accounts, no servers, no sign-in, no analytics. Play on a plane. Ads are non-personalized.
REMOVE ADS
One purchase, ads gone forever. No subscriptions, nothing to grind. Your first few levels are ad-free either way.
