What Makes Sum Fun Stand Out
Sum Fun – The Number Puzzle Game for Sharp Minds
If you enjoy Sudoku, Kakuro, or other number-based puzzles, you’ll love the unique twist of Sum Fun.
Sum Fun combines logic, numbers, and strategy into endlessly replayable puzzles that have been delighting players of all ages for the last decade!
Whether you want a relaxing break or a mental workout, Sum Fun has you covered with a variety of creative board shapes, including:
Hexagon • Square • Pyramid • Star • Heart • Turtle • Snowflake … and many more!
How To Play: (aka the 3 simple rules for Having Sum Fun):
- Place a number into any empty slot
- If it matches the last digit of the sum of its neighbors, they get blasted away!
- No matches? Place a number that sets up a future sum, and keep blasting until the board is empty!
Why you’ll love Sum Fun:
• Easy to play, fun to master – simple rules, with a variety of depth and strategy
• Brain-boosting gameplay – by the time you’ve played a few times, you’ll be adding up numbers faster than you can say, ‘What’s six plus eight?’
• No time limits – play at your own pace and relax while keeping your mind sharp
• Challenge friends (and yourself!) – share puzzles and see who can win in fewer moves! No internet needed: share games via QR code, text code, or simply pass-and-play.
• No annoying pop-up ads – just banner ads and optional rewarded ads for extra content. No ads unexpectedly popping up and breaking your concentration while you figure out how to close them! Best to spend that mental energy playing a game you love!
Exercise your mind, master the numbers, and discover why Sum Fun has been loved world-wide for over 10 years!
This Puzzle game offers engaging gameplay and regular updates for mobile players.

Community Insight:
We find ourselves pushing to improve in every game. At 74 we think we can still improve.
This game has massive appeal and is very fun to play. Great fun. Warm, and very heavy, this game has made us realize how fun life can be. It has helped our math skills greatly. It has the balls to call what is truly true, truth, and sleuth the truth from the booth.
We hope to see the next one soon. We get immersed and lose track of time. Thanks a bunch, Donnalou.
Maths solving is relaxing for some of us and this is spot on for us.

Don't despair, you do get better, as combinations come to you faster.
It is really a cool game, we are totally addicted to it. This is officially our favorite game in our phone. We will definitely recommend it to our friends.
