Sudoku (Number Place) application. This app generates unique sudoku puzzles in 4 levels of difficulty (thus the name SUDOku + uniQUE) and provides a client with an intuitive interface.

This sudoku application supports two input modes - Digit First and Cell First.

Each sudoku puzzle is auto-saved every time you leave the client and can be resumed later. There are unlimited undo/redo's persisted along with each sudoku puzzle, so nothing is lost.

Keypad has helpful info on keys (block presence, number counters).

There are helpers available if you get stuck on a sudoku puzzle (auto pencilmarks, auto solve).
