How to play Lone Number?

Lone Number is a fast-paced visual puzzle game that challenges your focus, memory, and attention to detail.


In each round, a set of numbers between 0 and 100 will appear on the screen. Most of these numbers appear more than once - but one number appears only a single time.

Your goal is simple:

• Scan the board quickly and identify the only number that appears once.
• You have 15 seconds to spot it and make your choice.
• Pick the correct number to move on to the next round - where things get even more complex.
• Choose wrong, or run out of time, and the game ends.

As you advance:

• The number of total digits increases.
• Patterns become harder to detect at a glance.
• You'll need sharp observation and quick reflexes to keep up.

At the end of the game, you'll earn points based on how many rounds you completed. Use these points to unlock new minigames and challenge modes across the app.
