Put a specimen on the lab turntable and cut it to a target weight. A target card might say "Cut off 30% by weight, left pan". Turn the specimen, lay a laser line across it, adjust its handles and press Cut. The smaller piece drops onto its pan, and the beam shows the true percentage.
The inside matters. Dense stones, hollow geodes and steel pins move the balance point, so a cut that looks right can miss. The X-ray view shows the inner bodies. Titanium tags are hard, and a cut through one breaks the blade. You have three blades per attempt.
Each level has one to three steps. A cut within ±2% of the target passes the step, and closer cuts earn more stars. A failed level can be retried at once, and retries are free and unlimited.
There are 120 levels in four labs: Fruit, Geode, Machine and Sculpture. Levels unlock in order, and each lab opens when you complete 20 levels in the one before it. Each lab has its own specimens and bench.
A weight preview shows the percentage a cut would give before you press Cut. You start with three preview tokens, and an optional rewarded video can also unlock a preview once per level. When the last blade breaks, an optional rewarded video can give one more blade, once per level.
The game contains ads and offers in-app purchases. Interstitial ads appear only when you leave a result screen. They never appear before level 4 is completed, at most once every two completed levels, and at least two minutes apart. Remove Ads is a one-time purchase that removes interstitial ads; rewarded offers remain. Weight Preview ×10 is a consumable pack that adds ten preview tokens.
The game is for players aged 13 and over. It plays offline. The internet is used only for ads and for purchases through Google Play.
Cut 3D specimens to an exact weight percentage, and watch the insides.
