Zener Cards

How to play

1. A shuffled deck of 25 cards (5 of each: circle, cross, waves, square, star) is sealed.
2. For each card, take a slow breath and tap the symbol that arrives first.
3. After every tap you'll see if it was a hit — keep going through all 25.

What to expect

Chance is 5 hits out of 25. The header tracks hits, deviation (Δ), and a z-score — |z| ≥ 2 is unusual, ≥ 3 is rare. One run is just a snapshot; patterns appear over many.
