Ninja Master a simple and very fun game.
Use the jag to cut all the fruits that are rotating on the screen, each time you play there will be a lucky round that will give you more gears in each level. In order to draw in time and not spend a lot of gears, you should carefully calculate to align the fruits with each other to cut all of them as easily as possible and score the maximum score in that level.
Using gear can at least cut those fruits. The difficulty will increase with the levels, but I believe with your intelligence, those levels will not make it difficult for you.
