## What is Sum?

Introducing 'Sum: Simple Math Puzzle', a captivating and mentally invigorating game that will transform the way you think about basic math.

Is there anything more fundamental than addition? Yet how challenging can it be when the clock is ticking, the stakes are high, and you're racing against time? We invite you to step up and find out!

At the heart of our game is a simple yet intriguing premise: a 3x3 grid randomly filled with 5 numbers. Your task? Make as many correct sums as possible before time runs out.

But it's not all that straightforward.

We offer four stimulating game modes, each delivering a unique flavor of fun and intensity:

> Classic: Dive into 90 intense seconds of mental agility, where every correct sum you find rewards you with additional time. But be careful - an incorrect sum could cost you precious seconds!
> Rush: The adrenaline-packed mode where every second counts. Make as many correct combinations as possible in 90 seconds. There are no time extensions or deductions - only pure, fast-paced fun.
> Infinity: Fancy a relaxed, untimed experience to refine your skills or unwind after a long day? Infinity mode lets you play at your own pace, with no time constraints.
> Epic: For those who enjoy a good challenge, our Epic mode presents a given sum upfront. Your mission? Find numbers from a filled up grid to form the sum. Same time rules apply!

Master the rules of the game - select the sum first, then pick the two numbers that add up to it. A correct combination looks like 20 = 8 + 12 or 20 = 12 + 8, not the other way around!

As you ace each level, you'll earn bonus time to help you reach even greater heights. There are plenty of opportunities to earn bonus points, especially in Classic mode.

'Sum: Simple Math Puzzle' also offers:
- Various levels of difficulty to keep the challenge fresh.
