Try to place all the marbles the their own target destinations at an order, by using their reflections from couple of mirrors. In the game there are 5 different mirrors and a wormhole to make some levels even more exciting. There are 4 sections, every section contains 20 levels and all of them have their own degree of the difficulty which has been prepared carefully. With it's simple gameplay and elegant game structure 80 puzzles for your brain exercise are awaiting. When you finish all the puzzles, the "Philosopher's Stone" level will be unlocked. Have fun.
Katakana Game
Read full descriptionHide full description
This is a simple game app that explains katakana words in Japanese. I will explain randomly displayed katakana words without using katakana words. Other than the questioner, if you listen to it and answer what katakana word it is, you will get points. It can be enjoyed by two or more people with one smartphone. Since it is a simple game that katakana words are displayed every time you tap the button, you can freely decide the rules such as the time limit and order. You can also change the number of displayed katakana words, so you can choose your favorite katakana words for the question.
