Imageepoch likes to make browser mini-games as promos for their console games. They created a cool one for Sol Trigger where you click on Fran to attack her. Complete it and you earn a code for item for Sol Trigger as a reward.
Time and Eternity: Toki Towa has a mini-game too, but it won’t unlock anything for the PlayStation 3 game. However, this mini-game will probably get more attention because it features Princess Toki taking a shower.
Shower Time with Toki is a simple game where you click like a crazy to make the steam go away. I don’t think it’s possible to "beat" the game in one round, but you can continue by linking a Twitter account. Before you play it you might want to turn your volume down because Toki can get quite vocal.
