ESPlay

ESPlay tests the theory that some people can predict the future by reading their own future thoughts. A unique audiovisual cue will play when the correct option (ie the option randomly selected by your browser) among your 5 image choices is displayed to you at the end of each round, and you can play that same cue before choosing an option to try to tap into your thoughts at that unique moment in your future. Can you read your own mind?

Controls:

• Arrow keys: navigate options
• Enter: select option
• Spacebar: play audiovisual cue
• 1,2,3,4,5: select respective choice, numbered from left to right
• s: enable or disable saving of stats to your browser's localstorage area across sessions (no data is recorded or transmitted anywhere else)
• d: select option to delete any saved stats from your browser's localstorage area (can then press enter to actually delete them)

Mouse control is also enabled.

Regarding the statistics, the probabilities computed show the likelihood of getting as many correct answers as you have or more in the given number of trials, so a lower probability indicates a more exceptional performance.

Also, note that if you have a large number of trials (eg thousands), the probabilities may become off if your browser starts to have trouble with the increasingly large numbers involved in the probability calculation, so if you think the probability seems wrong, it probably is. However, the # of correct guesses and # of total trials should still be accurate, and you can compute the probability with a more robust calculator/program using the below formula:

Probability = SUM[from k = x to n] ( (n!)/(k!(n-k)!) * (0.2^k) * (0.8^(n-k)) )

where n is the total number of trials (eg games played) and x is the number you guessed correctly. 

Regarding the "All-Time Stats" section, if you choose to enable saving statistics, these will be saved to your browser's localstorage area each time you make a guess so that you can record and reload your stats between sessions. If you clear your browser's localstorage (which you probably should be doing periodically), these saved stats will be lost, so if you have stats that you are particularly keen on keeping, you should record them elsewhere rather than relying on this function.

No data is recorded anywhere besides locally in your browser, and you can disable saving data and/or delete already saved data from your browser using the in-game buttons (or by clearing your browser's localstorage area). Also, note that the All-Time Stats will not include any trials played while saving stats is disabled (including within the same session) to prevent padding one's stats by choosing to record them only after making a correct guess.
