3D online claw machine · custom prize draw
A 3D claw machine with depth and Taiwan-inspired items. Aim and lift the original item, then reveal prize contents drawn by remaining quantity. Customize prize names and quantities.
How to play
- Edit prizes: Set 1–60 prize contents, names of 1–80 characters and positive whole quantities, up to 1,000,000 units in total. Appearance comes from the item you pick up in the machine. Saving starts a new round and clears records.
- Drop the claw: Drag the joystick or focus it and use arrows / WASD. ↑ moves away, ↓ toward you. The gray ring marks the drop point. Lift the item you aim at, then reveal its random prize contents.
- A little luck for you: The physical item is determined by contact at the drop position and never changes during pickup. Prize contents are drawn separately using the shared unbiased Web Crypto integer generator, weighted by remaining quantities. Contents are reserved on Drop and revealed at the chute. Aim, appearance and animation do not affect prize probabilities; skipping never rerolls.
