SudokuWare has been submitted to the Google Play Market.
Now I can disclose that the other 2 games, besides the classic Sudoku, are:
-Puzzle Sudoku: a puzzle with pieces of different size and shape, that must be recomposed, instead of an image, there is a sudoku Schema.
-Arcade Sudoku: an Arkanoid or breakout-like, where the wall is the Sudoku schema, and the bricks are the digits. No brain, no logic, only reflexes. when hit, the digits fall down creating a nice "flipper-like" effect making the game more interesting.
Classic and Puzzle have got 12 levels each, and you can save the game (one save for each level), in order to continue when you please.
Time records are saved too. At present, records are saved locally, no connection to the Internet is required.
From a technical point of view, I concentrated on the User Interface, and developed a mini-micro Windowing system to display scrolling windows and input buttons. Moreover, there is a massive usage of getImage and saveImage commands in order to create the pieces of the Puzzle game and dynamically the window contents, and set<Text,Sprite>scissor for windows management. About the Arkanoid game, the only noticeable thing is the usage of spriteRayCast() and getRayCastSpriteId() to improve bouncing capabilities.
Here are the screenshots.
