Sum Tracks

Non-maths geniuses steer clear, otherwise you’ll end up wracking your brains and pulling your hair out with Sum Tracks, a quick-thinking puzzle game and mental maths workout. Link different numbers together to get the final figure down to zero. The game has 45 increasingly difficult levels. The first few are pretty easy, but the further you get in the game, the harder the brain-teasers become, really putting those grey cells to the test.
