Number Guess is a classic game of "High-Low" that serves as the perfect introduction to algorithmic thinking. Behind its simple exterior lies the principle of binary search—one of the most fundamental concepts in computer science.
Why this game is fun?
There's a subtle psychology to guessing. Each attempt gives you a definitive boundary, slowly shrinking the world of possibilities. The moment you narrow it down to two or three numbers and finally hit the correct one creates a satisfying "Eureka!" moment.
