This time it was pretty fast, only a couple days for approval and game is already available for purchase.
All-in-One Mahjong for BlackBerry Playbook.
Btw, latest Mahjong game for mobile device features guaranteed solvable layouts, what means there is only at least one way to remove all the tiles without reshuffle.
It took me sometime to implement this feature, as I had to modify both the game and layout editor, I use to create layouts.
I will try to explain the solution later.
