Su Doku Classic 2

Su Doku Classic 2 is a Sudoku variant. The gameplay, described below, is exactly the same as Greenstreet's Su Doku though the colours and styling in this game are slightly different and the game has, allegedly, ten thousand new hand crafted puzzles.

The rules: The game is played with nine grids. Each grid contains nine squares arranged in a 3 x 3 formation as are the nine grids themselves. The program fills numbers into some grids and the player has to put the right number into all the remaining squares. In every square, vertical row and horizontal row every number of 1-9 has to be there exactly one time. Though numbers are used they are purely used as symbols, the game requires logic, not maths, skills to complete.

The game screen has two main areas. On the right is a red 3 x 3 grid holding the numbers 1-9. On the left is the Sudoku grid. The player examines the Sudoku grid and decides that, say, a number 3 belongs in a particular square on the main grid. Then, using the mouse, the player clicks on the number 3 in the left hand grid and drags it to the desired location on the Sudoku grid. If the 'Indicate Illegal moves' option is turned on the squares beneath the number being moved will change colour to either red or green, red meaning that the placing the number there would be an illegal move, and green meaning that such a move would be legal. While this is a help it is not a cheat as such because there may be multiple places in the grid which are legal moves. If the 'Indicate Illegal moves' option is disabled all squares over which the number being moved passes turn yellow.

This game features over 10,000 puzzles, three difficulty levels, hint and next move functions for beginners, a save feature, and a print function so the player can solve the puzzles without a computer.

The game also features a 'boss key' which instantly minimises the game, but keeps it running. This is intended for those players who play the game at work in quiet moments and whose boss may make unexpected visits.
