Hapless Wheels is a side-scrolling obstacle-course racer inspired by Happy Wheels. Pick a rider, get their vehicle moving, and try to reach the golden finish star without losing the ability to keep going. A clean landing matters more than holding the accelerator down.
The five vehicles change how each course feels: a rocket wheelchair, a self-balancing gyro board, a bicycle with a passenger, a motorized shopping cart, and a turbo moped. Each has its own abilities. The wheelchair can boost across gaps, while the moped trades control for speed.
Fourteen ways to get into trouble
The levels move from tutorial hills to rooftop jumps, minefields, swinging wrecking balls, factories, and loop-the-loops. Props participate in the physics: glass breaks, bridges can snap, barrels trigger chain reactions, and dominoes knock into whatever is behind them.
Checkpoints make another attempt quick. Best times stay in the browser, and finishing against a level’s target time earns a gold, silver, or bronze medal. Settings let players adjust body toughness and the amount of blood and gore, including turning the latter off.
The character picker makes each vehicle’s speed, control, and toughness visible before a run.
The physics behind the crashes
Planck.js, a JavaScript version of Box2D, handles the simulation. Each rider is a ten-part ragdoll connected by joints. Motors help those joints hold a riding pose; enough force can break the connections. The game advances physics in fixed steps at 120 Hz, while Three.js draws the scene and follows the rider.
The visual and audio assets are generated in code: canvas supplies textures, and Web Audio synthesizes effects. The project is organized into separate modules for riders, vehicles, level objects, courses, rendering, effects, sound, and input. Vite builds the result into a static site.
Take a run
Play Hapless Wheels. On a keyboard, W/S or the up/down arrows control movement, A/D or left/right lean the rider, and Space activates the primary ability. Enter retries from a checkpoint; R restarts the course. Gamepad and touch controls are also available.
This is a fan-made homage with original characters, artwork, and levels, unaffiliated with the creators of Happy Wheels. The public repository contains the source, controls, and local setup instructions. GitHub records its creation on October 3, 2026.
