Bonk Lab
A free ragdoll physics game about excellent bad ideas. Launch a jointed little test subject into neon bumpers, chain impacts and clear twelve experiments. No signup, no app download.
How to play Bonk Lab
Choose an angle and power, then launch. You can also drag from the launch zone toward your intended flight direction and release. First hits on a bumper award a bonus. Hit every bumper in an experiment for an extra 800 points.
Clear the target to unlock the next experiment. Earn a second star at 1.4 times the target and a third at twice the target. Experiments end after ten seconds or once the ragdoll settles. Reset is always available.
Controls
Mouse or touch: drag to aim, release to launch. Keyboard: Tab to the angle and power sliders, adjust with arrow keys, then activate Launch experiment. Sound is optional and off by default.
