Math Slicer Free by Tumbstorm is a fruit ninja clone with a math educational twist. In this version you use your fingers to cut the numbers that match the answers to equations displayed in the background. By playing the game you win eggs that you can use to unlock other levels, slices and even power ups. You can also buy more eggs if you don’t have enough for the items you want. The music, sound effects and graphics are ok. The animation when you slice a piece of fruit is very good.
Overall the concept is great. Taking a familiar and popular game and making it into an education game is a great idea. I really tried to love the game but I struggled with what star rating to give it. First on the Kindle Fire that I tested it on, the slicing of the numbers is awkward. After a few minutes of playing, I got the hang of it (smaller children might get frustrated). I didn’t have the same issue with the Google Play version. Also for some reason the Amazon Kindle version is not recognized by Amazon Free Time as a valid educational app.
Although the issue above is annoying, my biggest issue is with the egg in-app store. Small children might end up buying eggs for real money. There is no mechanism to stop small children from buying eggs. The paid version removes the ad banner but retains the in-app store.
Available in the Amazon App (Kindle Fire), the Apple App and Google Play store. I tested the Free version (the paid version does not have ads but still has an in-app store) on my Kindle Fire HD+ and a recent Android phone.
