About this tool

Guess the Number (Badly) is the classic higher-or-lower game with an unreliable narrator. The computer picks a number from 1 to 100; you guess and it tells you higher or lower, plus hot, warm or cold. About one hint in five is unhelpful on purpose.

The smart strategy is still to halve the range each time — start at 50 — but be ready for hints like "It is a number. That is all I will say."

Who it's for

Kids

Number sense practice.

Classrooms

Breaks

Quick puzzle.

Tips & tricks

  • Start at 50.
