Frequently Asked Questions
What is the best strategy?
Binary search: guess 50, then halve the remaining range each time — 1–100 cracks in 7 guesses maximum. Random guessing averages far worse.
How do hints work?
Each guess reports too-high or too-low, narrowing the window visibly. Five attempts or fewer marks sharp play.
Can I play again?
Yes — new random number every round with attempt history kept per session. Race friends for fewest guesses.
Is anything uploaded?
No — the game runs entirely in your browser. Nothing leaves your device.
