How to Play

Six shapes appear simultaneously. One is the odd one out — the rest are identical distractors. Click the odd shape as fast as you can. The moment you click, the next set appears instantly. You have 30 seconds. No breaks. No rounds. Just a continuous blitz until the clock hits zero.

Difficulty Guide

0 – 10 SECONDS OBVIOUSLY DIFFERENT
Seconds 0–10
Clear shape differences — triangle vs pentagon, square vs hexagon. Gets you into rhythm fast.
10 – 20 SECONDS ONE SIDE DIFFERENT
Seconds 10–20
Same shape family, one side different — pentagon vs hexagon, 5-point vs 6-point star. Requires counting.
20 – 30 SECONDS TINY VERTEX SHIFT
Seconds 20–30
Nearly identical shapes — one vertex barely displaced, mirror images, star inner-point variations. Requires 1–2 seconds of focused attention to spot.
SCORE 100,000 per correct answer − reaction ms WRONG = 0 + LOCKOUT MORE CORRECT ALWAYS WINS
Scoring
Each correct pick = 100,000 points minus your reaction time in ms. Wrong answers score 0 and trigger a lockout penalty. Most correct answers wins — speed breaks ties.

🛡 Fair by Design

All players in a lobby see the exact same shape sets in the exact same order. The room code seeds every set — which card is the odd one, which shape types appear, what rotation each card has, what colors appear — all generated deterministically before the match starts.

01

Identical sets for every player

Every player in the lobby sees the same odd card index, the same shape configurations, and the same background colors for every set throughout the 30 seconds. The difficulty ramps identically — nobody gets an easier sequence.

02

Server validates every answer

The server independently computes the correct answer for each set using the same seeded RNG. You cannot self-report a correct answer — the server rejects answers that don't match. Wrong answers are tracked, spam clicks are rate-limited, and invalid coordinates are rejected outright.

03

Score is pure recognition speed

With identical layouts and server-validated answers, the only variable is how fast you spot the odd shape. Most correct answers wins. Speed breaks ties. No luck, no tricks — just perception and reaction time.
