Number Guessing Game

Sobre esta ferramenta

Play the classic number guessing game with a twist — after you solve it, the game shows the binary search strategy that would have found the number in the minimum possible guesses. Choose Easy (1–50), Medium (1–100), or Hard (1–1000) difficulty, or set a fully custom range. The computer picks a secret random number; you guess and receive 'too high' or 'too low' feedback until you find it. A visual history list tracks every guess and narrows the displayed range in real time. The info panel always shows how many guesses you've used and the theoretical minimum (⌈log₂ n⌉). After solving, an animated walkthrough demonstrates the optimal binary search path step by step. In Reverse Mode, you think of a number and the computer guesses it using binary search — you only reply Higher, Lower, or Correct. Perfect for understanding algorithmic thinking and search complexity.

Como usar

1. 1 Choose a difficulty (Easy, Medium, Hard) or set a custom min/max range.
2. 2 Type your guess in the input field and press Enter or click Guess.
3. 3 Read the 'Too High' or 'Too Low' hint and use the narrowing range display to plan your next guess.
4. 4 Continue guessing until you find the number — your guess count is tracked throughout.
5. 5 After solving, click 'Show Optimal Strategy' to see the binary search walkthrough.
6. 6 Try Reverse Mode: think of a number and let the computer find it using binary search.
