About Tolerance: Mechanical Puzzle
Tolerance is an adult, quiet, precision 3D mechanical puzzle.
Each level presents an industrial assembly: machined blocks, prisms, pyramids, cylinders, cones and wedges, fastened with screws of varying heads, finishes and sizes. Your objective is complete disassembly.
KEY FEATURES
• Solid 3D mechanics: parts interlock, stack and drop under gravity once unfastened.
• Fair and solvable: an offline solver proves every level has a solution. Stuck? Undo and try another order.
• Park slot: stage a screw for later, or drag a tray screw onto a parked one to swap them.
• Shapes: cylinders, cones, pyramids, prisms, frustums and wedges. Some are sliced into layers, each with its own outline.
• Formula sheet: see the shape drawn see-through with its dimensions, angles and formulas for volume and surface.
• Easy, Medium or Hard: every level has a countdown. Each difficulty keeps its own results and unlocks.
• Global board: sign in with Google, join with a name and compete on your best total per difficulty. Delete your board data any time.
• Intro: each rule is shown with a short demo.
• Pick up where you left off: the level list opens at your last cleared level.
• Hints show the next move. Undo is free and unlimited.
• Par and Perfect marks, with per-level stats. "What you can improve" picks the levels with the most score to gain.
• Match screws by head type, size and finish, not color alone.
• Over 350 levels, from first steps to large assemblies of up to 64 screws.
• Nine material sets, including Titanium, Blued Steel, Ebonite and Verdigris.
• Sound effects, screw animations and haptics. Each can be turned off.
• Color themes in light or dark, and 20 languages.
• Back up your progress to a file and restore it later.
Industrial look: brushed steel, brass and black oxide.
Unscrew. Disassemble. Calibrate.
