How it works
Simple. Scored.
Same for everyone.

No vocabulary. No trivia. No luck. Pure logic and pattern reasoning — the same five questions for every player on earth, every single day.

01

Play today's challenge

Five questions. Sixty seconds. Logic traps, pattern sequences, lateral thinking — one objectively correct answer each. No ambiguity, no opinion, no luck.

02
⛓️

Build your chain

Every correct answer is worth 150. Answer quickly for up to 30 more, and each answer that follows a correct one adds another 25. A wrong answer breaks the chain — but it never takes back points you have already earned.

03
🎯

See your Clarity Score

A score from 0 to 1,000, your real placement among that day's players, and your Clarity Level — updated live as thousands play the very same questions.

Your score
means something.

Every score maps to a Clarity Level — so 731 isn't just a number, it's Focused. You always know exactly where you stand and what you're climbing toward.
