This is a game that is in its prime. Welcome to one&n.
The objective of the game is simple: you need to add numbers together to get prime numbers. But dont go over your target, or youll lose precious time to get a high score.
Sure, we didnt have to do a game with prime numbers, but otherwise it would be a maths test for seven-year-olds!
Put your number skills to the test - but dont worry if you arent up to speed on your prime numbers, as youre told the next one to aim for at the bottom of the screen.
If you need extra help at any point, get helpful hints with our coloured numbers feature.
