Happy Wheels is a physics-based browser game where players guide different characters through hazardous obstacle courses filled with traps, slopes, and moving hazards. The gameplay focuses on ragdoll physics, meaning every movement is influenced by momentum, balance, and impact. Players must carefully navigate each level while avoiding spikes, gaps, and mechanical obstacles that can instantly stop progress. Each character comes with slightly different movement styles, adding variety to the gameplay. Success depends on timing, control, and understanding how the physics system reacts to terrain and speed. Levels often require both patience and quick reactions, making each attempt feel unpredictable and engaging. The combination of simple controls and challenging level design keeps the gameplay dynamic and skill-based.
