About this game
Sum4Fran is a mental math game that also trains your memory. In Chain mode, the first calculation appears complete, but then only the new number is shown, and you need to memorize the previous result. Each correct answer increases the chain, and the longer it gets, the more your brain is challenged.
A DAILY CHALLENGE FOR THE WHOLE WORLD
Every day there's a new sequence of calculations, exactly the same for all players. Your first attempt is the official one, and you can repeat it as many times as you want to practice. Share your score and challenge your friends with a link.
SEVEN MODES TO PLAY
Play the classic Chain, solve the complete operation at your own pace, or race against the clock in 60-second matches. Test your limits in Precision mode, where a single mistake ends the round. There's a relaxed practice mode without a timer, a local duel for two players on the same device, and a 60-stage journey with stars to conquer.
A MATH COACH THAT EVOLVES WITH YOU
Difficulty subtly adjusts to your performance. Master simple sums and larger numbers will come naturally. Level up, complete skill missions, track your progress with real accuracy, speed, and score graphs, and see how well you've mastered each multiplication table, addition range, and subtraction. The Kids, Normal, and Hard presets make the game work for both children learning their first sums and adults looking for a serious brain workout.
PLAY ANYWHERE, YOUR WAY
Sum4Fran works completely offline, so you can practice mental calculation on a plane, on the subway, or anywhere without needing Wi-Fi. Nothing interrupts your game, there are no automatic ads, and the game doesn't collect data. An optional daily reminder helps you maintain your streak, and accessibility options include adjustable text size, a simplified font, reduced animations, and colorblind-friendly symbols. Available in six languages.
Whether you call it brain training, quick math practice, or simply a fun way to get faster at arithmetic, Sum4Fran transforms a few minutes a day into real, visible progress.
