David let us know that Tiny Bite Games has ported their Gem Spinner II: Water Quest game to the BlackBerry PlayBook. The game seems to be built on the Marmalade SDK but I could not confirm that. Its an addictive yet classic gem matching game that plays beautifully on the PlayBook.
Check out the trailer for the game below:
You can pick up the premium version of Gem Spinner II for $1.99 in App World or pick up the free version that has the first 20 of the 50 levels.
