Startup Tingly Games fuses greeting cards and casual games

You can now surprise your grandma who just learned how to use “the Facebook” with an e-card that has Sudoku built into it.

Greeting Games, publisher Tingly Games’ new service, turns casual video games into virtual greeting cards. It’s available at greetinggames.com. It’s now in beta-testing and available to try for free until the end of the month. After that, Tingly will offer a subscription model and permit nonsubscribers to buy individual e-cards.
