Sum Fun, the puzzle game that builds your number and strategy skills! Enjoyed by both kids and adults around the world.

We’ve been busy expanding the game designs! Test your number skills in more creative ways with nine challenging modes:

• Square • Pyramid • Football • Flappy • Heart • Robot • Invader • Ghost • Turtle •

Sum Fun is –

• Easy to play
-- No time pressure – just good ol’ puzzling and problem solving. Take a number and place it into an empty square. If it matches the last digit of the sum of it’s neighbours, they’ll get blasted away. Try to empty all the squares in as few moves as possible!

• Fun to master
-- Uncover the strategies needed to get the best scores. Can’t find a place to put any of the pieces? Plan ahead by placing numbers to set up a sum for a future move.

• Fun with friends
-- Send challenges through messages or Airdrop and see who can finish the game with the fewest moves!

• Endless variety
-- Each game is created randomly – no two games are alike! Choose from nine different designs and find the strategies to solve each one!

Have Sum Fun, and exercise your mind!

Great game

I find myself pushing to improve in every game. At 74 I think I can still improve.

Maths Muse

Maths solving is relaxing for some of us and this is spot on for me.
