Research shows that too much sugar rots your teeth and your mind, making it hard to concentrate. Put the candy to one side and give your brain a real workout with Innecto. Let Innecto lull you into a false sense of security and confidence. It’s so easy - it’s so relaxing. Those little tiles twist so satisfyingly into place as you race against the clock to complete each board in the least time with the least number of moves. By the time you get to level 56 you’ll be whizzing through (although those little tiles can be a little fiddly on the iPhone) and then… Oh no! Level 57 has a nasty surprise in store - can you get all the way to the end? No two games are ever the same either - each level is calculated by the computer so each play through is never the same twice.

Verdict
The clearest difference is price: Sum Fun at Free against Innecto's $0.99. Sum Fun also leads on in-app purchases (none vs 1) and update cadence (weekly vs every 8 months). Innecto's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.0). On review sentiment and device support there is nothing between them.
