🧠 How to Play SumUp
SumUp is a logic-based number puzzle where your goal is to make the sum of numbers in each row and column match the target values shown at the edges of the grid.
🔢 Selecting Numbers
To play, tap on the numbers in the grid to mark them red – this means they won’t be included in the sum for that row or column. All unmarked numbers (those left in grey) are counted toward the total.
✅ Reaching the Correct Sum
Once the numbers you’ve left unmarked (grey) add up to the target sum for a row or column, the number at the end of that row or column will turn green – this means it's correct! Your goal is to turn all row and column targets green to complete the level.
💣 Challenges Ahead
As you progress, new obstacles will appear:
– Hidden numbers you can’t see right away
– Untouchable tiles that can’t be selected
– Even bombs that add extra risk and strategy
🌟 Scoring & Stars
After each level, you'll earn up to 3 stars based on your performance.
– Finish faster to get a better score
– Avoid using hints to maximize your stars
Can you beat every level with a perfect 3-star score?
💡 Using Hints
Stuck on a tricky puzzle? Don’t worry – you can use a Hint to help!
Just tap the Hint button during a level.
You’ll be shown a short rewarded ad, and once it finishes, the game will automatically mark one number in its correct state (either red or grey) to guide you toward the solution.
Hints can be a great way to move forward without guessing – but remember, using them will reduce your final star rating, so try to solve levels on your own for a perfect score!
