I tried Mobile Kingyo Sukui 2 (Mobile Goldfish Scooping 2) on Sharp Zaurus SL-C3100 today. This Kingyo Sukui, or Goldfish Scooping, is a popular game in Japan where you try to catch a goldfish using a fish net made of paper. If the paper breaks, you lose, and if you catch the goldfish, you get to keep it.
Some people catch dozens of fish, although some goldfish scooping shop at the festival allows you to only keep several.
The game is very simply made, nothing like modern games on Android, but will be fun for killing time on the go. You can download the game here. The photos below were taken with 2006 Canon IXY Digital 800IS.
