About One Up Game

So you think you can add quickly? One Up Game gives you the chance to prove how much of a genius you really are.

Starting with level 1, you'll be presented with 4 numbers such as 1234, simply add 1 to each number using the keypad so that 1234 becomes 2345. Do it as quick as you can within the time allowed.

Level 2 to 9 adds one to the number so that in level 2 you will have to add 2 to each number such as 1234 becomes 3456, then level 3 adds three to the number so that 1234 becomes 4567 until you reach the absurd level 9.

You need a score of 3 or more points to pass the level, sounds easy right - let's see how you do. If you're a real brain, then change the default score needed to something higher or change the timer from it's default to 15 seconds.

Be careful, if you enter a wrong number your score is reduced!

it's a fun game to test your mental reflexes and a great game for anyone trying to add numbers quickly.

Enjoy.
