Inner Compass
Zener cards — an intuition training exercise
The classic set uses five simple symbols: a circle, cross, three waves, square and star. In this online game the card is hidden, and the player's task is to notice the earliest image, hand impulse or bodily response.
The full set is selected in advance
The candidate set, hidden symbol and secret key are sealed with a SHA‑256 code before your answer, so the game cannot adjust the card afterward.
Two to five choices
The chance of a random hit ranges from 50% with two cards to 20% with five. A single session is not scientific evidence of unusual abilities.
