## What is Don't trust your luck?

This is not a game to get rich. It is an experiment to face the truth.

Many believe they are "the chosen ones." They trust their gut over probability. We built this app to break that illusion. We removed the flashy casino lights and the tempting sound effects, leaving only the cold, hard core—Data and Luck.

Why "Don't Trust Your Luck"? Here, there is no house edge and no background manipulation. Every result is generated using SHA-256 and SHA-512 encryption algorithms. We provide a built-in "Fairness Verifier" that allows you to check the hash of every round yourself.

When the environment is absolutely fair, you will realize a brutal truth: in the long run, luck is unreliable. This is the Law of Large Numbers.

【Core Features】

Provably Fair: Transparent, open-source verification logic. No black boxes.

Pure Probability: A simple prediction game (0-100) to face the essence of chance.

Global Leaderboard: See who is temporarily favored by the goddess of luck, and who proves the ruthlessness of math.

No Real Money: Crucial Note: This app is for entertainment and educational simulation only. Points cannot be cashed out, withdrawn, or exchanged for real-world value.

【A Message to the User】 If you win here, enjoy the moment, but know it is a statistical variance. If you lose here, remember this feeling, and never gamble in real life.

Because in front of absolute math, there are no eternal winners.
