Sum Fun – the number strategy game

About Sum Fun

Sum Fun is a brain-training mobile game, great for all ages. You win by removing the numbers tiles from different shaped boards: place a tile into an empty slot, and if it matches the last digit of the sum of the neighbours, they get blasted away! 

More vivacious than Sudoku, more satisfying than matching candies, and more relaxing than reading the news. Sum Fun is an ideal way to take a break, and boost your brain at the same time!

As you play, you’ll not only become super-fast at recognising how numbers sum together, you’ll also develop the strategies needed to complete the various shaped games in Sum Fun – squares, hearts, robots, stars and more! Compete against your friends (or yourself!) to see who can finish each game in the fewest moves.

Sum Fun is coming in late 2022 to Android and iOS phones and tablets! But no need to wait – follow Sum Fun on Facebook for updates, and sign up below to start playing right now!
