Addition is one of the simplest and earliest mathematical tricks taught. Everyone ends up adding two numbers every day for some reason or the other. There couldn't possibly be anything more basic than this. If you've got so much experience, let's see how good you are at it. Can you add? The game is straightforward and simple - The game consists of a 3x3 grid. 5 numbers are generated at random, in random places of the grid. There are 4 different game modes to choose from: ★ Classic: You get 90 seconds to find as many combinations as possible. Scoring a correct combination gives you 3 seconds more, whereas a wrong combination will deduct 5 seconds from your remaining time. ★ Rush: Score as many combinations as you can in 90 seconds. No time bonuses or deductions. ★ Infinity: Play and practice for as long as you want without any time restrictions. ★ Epic: This time, the sum is given to you before hand, and you have to use as many tokens as possible from the grid to form it. Same time rules apply here! Score higher by using more tokens to form the sum. To make a combination, you have to select the "SUM" first, followed by the two numbers that add up to the sum. • Correct combination : 20 = 8 + 12 OR 20 = 12 + 8 • Wrong combination : 8 + 12 = 20 OR 12 + 8 = 20 Each time you pass a level, you get a bonus 30 seconds of more time. Time bonus: Can only be secured in the "Classic mode" by one of the following ways:- - Game duration > 300s = +1000 points. - Game duration > 420s = +2000 points. - Game duration > 500s = +3000 points.
