The Zener cards are a deck of twenty five cards, five of each symbol. The five symbols are: a hollow circle, a plus sign, three vertical wavy lines, a hollow square, and a hollow five-pointed star. They are used to test for ESP.

In a test for ESP, the experimenter picks up a card in a shuffled pack, observes the symbol, and records the answer of the person being tested, who would guess which of the five designs is on the card. The experimenter continues until all the cards in the pack are tested. A baseline of 20% is set as a 'guess by chance'.

Play the game and your results will get submitted to our database.

Please note

On each selection, the buttons are are disabled for 2 seconds, to allow the user to think about there next answer and not continue to click randomly skewing the results.

Adding additional visuals and sound effects, such as cardbacks
Adding additional data such as moon cycles to the results statistics
