The game holds a bank of 100 instruments across six senses (Geometry, Proportion, Time, Perception, Number, Motion). Each day, 5 are dealt from the bank, seeded from the date, so every player on Earth gets the identical five challenges. Sample instruments from the bank:
Each run resolves to one of six ratings, by percentage of a perfect score.
GUT CHECK is a daily instinct-calibration game: five rounds drawn from a bank of 100 instruments (draw an angle, fill a vessel, find a midpoint, count a flash, stop a blind timer, and 95 others) that pit your senses against exact targets in about sixty seconds. Everyone on Earth gets the identical five challenges each day, seeded from the date, so a single score out of 500 is directly comparable for every player, everywhere. Score out of 500, then challenge a friend to a duel or gather up to 50 people in a room with a shared leaderboard, or pass one phone around the table in GUT CIRCUIT (or play it online, each on their own phone), a Monopoly-style board game built from the same instruments. It runs in any browser, installs as an offline PWA, and needs no account and no tracking.
The signature element is an analog gauge (a half-dial with a red needle and pivot). The wordmark always keeps its red slash.
