With the Perception Test, you can train your perception. This app uses the Japanese Kanji for the training.
Once the game begins, any Japanese Kanji is displayed at the top of the screen randomly. You should choose one of two similar Japanese Kanji. The game is over when you have chosen a wrong Kanji. When you choose 15 Kanji characters without a doubt, the game is end, and the score is recorded to GameCenter for the ranking.
If you want to spent your time to grow yourself, please choose the Perception Test!
