One brain. Many ways to trip it up.

3 SECONDS is a mixed game of knowledge, reflex, memory, observation and precise actions. Guest play is free. No account, payment or advertising is required.

The name is the pressure. Each challenge receives time suited to its reading and execution load. Extra reading time, reduced motion, sound and contrast controls are in Settings.

Global rankings contain server-verified runs, grouped by engine, mode, language and timing setting. Verification checks the rules; it cannot prove that a human played without assistance.

Daily challenges reset at 00:00 UTC. Friend links preserve the original engine and sequence. Endless content adapts to the questions and mechanics encountered on this browser.
