About this game

Unlock Your Focus with Letter Number!

Letter Number is a fast, challenging game designed for players with sharp minds and top-tier concentration. It may seem simple at first—but mastering it takes serious mental agility!

How to Play:
A number and a letter appear together in a yellow box.
Your task? Decide based on the current prompt:
- Is the number even or odd?
- Is the letter a vowel or a consonant?

But here’s the twist:
The focus keeps switching between numbers and letters—forcing your brain to adapt in real time.
And as you give more correct answers:
- Time gets shorter
- The pace gets faster
- The challenge gets tougher!

Why You’ll Love It:
- Builds extreme focus and mental flexibility
- Trains both logic and reaction speed
- A true test of concentration under pressure
- Fun, addictive, and endlessly replayable

Stick with it, and you’ll uncover hidden powers of focus you never knew you had.
