From Shockwave Japan, this cute little Flash game requires you to click on adjacent animals to swap places and line up 3 or more of the same. It sounds a little confusing, and with the instructions in Japanese, I was a little confused at first myself. Just ignore the first screen with the cell phone, don't click it—it's an ad. Wait for the game to load and the Play button to show. I figured it out, and it's fun to play, so...
I'm taking Beginning Japanese over the summer, so hopefully I will get better at translating these Japanese games.
Update: Shockwave Japan changed the link so that you must first sit through a short advertisement. Rest assured the game will begin shortly after clicking the game link.
