One Plus One, as the name implies, begins with your ability to process one plus one.

Yes indeed, 1 + 1 = 2. But that's not the end; just the start.

One by one, you will have to trudge through one arithmetic problem after another, and that too, in a timed manner.

Cross over, and you will have unlocked the next level. 10 LEVELS marks the end!

But that's not it; you can still replay and beat your previous high scores. Think of this as a daily personal challenge to see if your brain can take it just a little further each day.

Can you get to the very end of this challenge?

Play the game and find out for yourself!
