Inspiration Test

Strictly speaking, this is not a "game", it is a small program for testing and training the human faculty of prediction.

It grew out of a simple thought: if a person truly possessed the ability to foresee, they could reliably beat the 50% probability line of a coin toss — and research suggests that, at moments of focus and life-or-death stakes, humans can indeed briefly break through probability. Yet humans also carry emotion and greed, which easily lead them to misjudge. And so, this was born:

Guess heads or tails, test your intuition and fortune, and earn points.

It tests neither reflexes nor speed — it tests one thing only: where your intuition points, before the answer is revealed.
