Thumdoku is the first Sudoku game custom-designed for the Blackberry Storm! A streamlined interface makes playing Sudoku more enjoyable than ever.

· Four levels of difficulty - Easy, Medium, Hard, and Insane
· An unlimited number of randomly-generated puzzles with eye-pleasing symmetry
· Smooth touch-and-click interface
· Unlimited undo/redo with a swipe of your finger
· Easily add and remove “pencil marks” (small numbers that help you remember possibilities for a cell)
· Automatically saves your game so you never lose your place
· Unobtrusive game time and real-time clocks
· Works in portrait or landscape mode
· Built-in help system
· High score board for recording your best times
· Options for automatic pencil mark removal, automatic puzzle verification, and more

The trial version is absolutely free and contains a few puzzles at each difficulty level.

· This update is basically a patch for 1.1. That version had some problems that could affect unregistered users — basically, the unregistered version would only let people try a single “easy” puzzle.
