Welcome to ‘CatBox the experiment’ an app that allows you to perform the ‘Schrödinger's cat - thought experiment’ while not causing any harm to real living cats.

The theory is to place a cat inside a box along with a randomly triggered anomaly that could cause the cat to die ( for example a poison ). With the box closed and the results of the experiment unknown, the cat is considered both alive and dead as its living state is unknown until you open the box.

‘CatBox the Experiment’ extends this thought experiment to a social level where the temptation to wait as long as possible with the risk of an incorrect guess may yield a higher score if guessed correctly.

Can you resist the temptation to check over the option to wait as long as possible while also avoiding the mistake of making the wrong guess? Only the cat will know... or wont know, depending on if its alive or dead!
