How to play Sum?

Sum is a fast-paced, brain-teasing number game where your goal is simple:
Add the numbers on screen before the 20-second timer runs out.
Here's how it works:

• Start the round with a small set of numbers displayed on the screen.
• Calculate the correct total and submit your answer before the countdown hits zero.
• Get it right? You move to the next level, and an extra number is added to the screen.
• Get it wrong? Game over - accuracy matters as much as speed.

As you progress:

• Each level becomes trickier, with more numbers to process under pressure.
• Your score increases the further you go, rewarding quick thinking and precision.

When the game ends, you'll earn points based on how far you got. These points aren't just for bragging rights - you can use them to unlock other exciting minigames and challenges within the app.
So stay sharp, act fast, and see how far your mind can go in Sum!
