About this quiz
Spotting an even number takes one glance at its last digit. Doing it 50 times in 45 seconds, in a grid with no order to it, is the hard part.
- A whole number is even when its last digit is 0, 2, 4, 6 or 8.
- Exactly half of the numbers from 1 to 100 are even.
- Clicking an odd number is counted as a mistake but does not end the game.
- Everyone gets the same grid each day.
