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.

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.

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.
