Play, privacy and fair scores
Games are free to try. No payment or account is needed. Personal stars and records are saved on this browser, not in an online account.
Shared rooms support 50 connections and expire after six hours. Anyone with the unlisted invite can join; use a nickname or team name. Host controls stay out of the player link.
The group buzzer accepts the first message received by the server. Network delay affects close races and shared timing scores. Solo reaction results also vary by device. These are playful personal challenges, not professional benchmarks.
Sound is off unless you turn it on. Games do not require sound. Reduced-motion system settings are respected; game-essential motion still appears in the moving challenges.
