Build it. Trigger it. Make it hop!

Build a machine that reaches the goal. Nothing moves until you press ▶ — then physics takes over and you watch your chain reaction succeed or fall apart. ■ puts every piece back exactly where you left it, and ↻ starts the level over from scratch.

Building

• ＋ opens the object list. The number on the button is how many objects you have left for this puzzle — each object shows its own count too.
• Pick an object, then tap the board to place it. Hold Shift to place several.
• Tap a placed part to select it — rotate, flip, duplicate and delete appear at the bottom.
• Drag parts to move them. Scroll or pinch to zoom, drag empty space to pan, 0 resets the view.
• Right-click cancels a tool — or snips a connection you drew.

The five connections

• ➰ Rope — ties two parts together. Flames and snippers cut it.
• ◎ Pulley — runs a rope over a wheel: heavy side sinks, light side rises.
• ⚡ Wire — a pressure plate fires a machine: cannon, launcher, snippers, or an on/off switch for fans, motors and belts.
• 🔌 Cord — carries electricity. Unplugged devices run on their own; the moment you plug one in it needs a live source.
• ⛓ Belt — links two wheels so they turn together. Touching gears mesh on their own.

Chains worth knowing

• Crank or windmill → gears → generator → cord → anything electric.
• Laser or lamp → mirrors → solar panel → cord → device.
• Light through a magnifier burns ropes, lights fuses and pops balloons.
• A switch in a cord run blocks power until something flips it.
