Software River Solutions have let us know about their new game called, Doodle Jewels. Doodle Jewels was one of the first games available for Z10 and is currently one of the top games in the puzzle category. I played around with the game for awhile and was hooked right away! Think BeJeweled, but with some added gameplay bonuses. No lag at all, and the graphics are great.
It comes in the "Lite" version which is free, and has limited number of playable levels, and a full version which can be downloaded for only $2.99. They could easily charge $4.99 for this game. It's that fun.
The developer told us that they also have versions for the iPhone/iPad and Windows 8, but they really think that it looks and feels the best on a Z10!
