Frequently Asked Questions

What defines lethal trauma versus survivable amputation in Happy Wheels?

Lethal trauma occurs when the cervical spine fractures (causing decapitation) or when the thoracic torso is crushed. Severing arms or legs reduces mobility and triggers a bleed-out timer, but does not disqualify the player from completing the level.

How does collision G-force scale with surface hardness?

Hard rigid surfaces like solid concrete stop ragdolls in 0.025 seconds, generating up to 240+ Gs of shock. Softer surfaces or breakable glass extend deceleration time, reducing peak joint stress by up to 50%.

How long can a character survive after losing an arm or leg?

Single limb amputations provide approximately 45 seconds of consciousness before blackout. Total four-limb bisection accelerates blood loss to an 18-second emergency survival window.
