Letter Number is a fast mental challenge that looks simple — until your brain has to switch gears every few seconds! A number and a letter appear together in a box. Sometimes you judge the number (even or odd?), sometimes the letter (vowel or consonant?) — and the prompt keeps switching!
HOW TO PLAY
• A number and a letter appear together in a yellow box
• Check the prompt: are you judging the number or the letter?
• Number: is it even or odd? Letter: is it a vowel or consonant?
• Answer correctly — and stay focused, because the rule will change at any moment!
THE TWIST
• The rule keeps switching between numbers and letters
• Your brain has to adapt in real time
• Time gets shorter as you progress
• The pace speeds up — how long can you keep up?
