In SUM Fun, your objective is to rearrange the values of items on the screen so that their sum equals the predetermined result. Each click on an item contributes to building the desired total. For example, if the target number is 17, you can click on 9 and then continue by clicking on 8 to achieve the goal.
The more items you successfully arrange, the greater the rewards you'll receive. Notably, achieving at least 5 items unlocks the opportunity to alter their values, introducing new strategic possibilities.

With 6 items, you earn a bonus of extra time, allowing for more thoughtful consideration of your arrangement. And if you excel to the level of 7 items, you gain an additional life, providing a chance to persist in the face of escalating challenges.
