While browsing Sega Japan’s site today, I found a section with some online games – including some Flash puzzles. They’re more fun than they sound, and quite challenging too, if you opt for the larger ones.
The puzzles can be found here, and include a large selection of Shining puzzles, from Shining Soul through to Shining Teas. Scroll down to the bottom of the page and you should find them.
Enjoy!
