Use the computer to generate an innumerable variety of 9 x 9 or 15 x 15 grids. The computer generated puzzles may have more than one solution. The default puzzles and the puzzles in the batch files have unique solutions.
Print the puzzle with a scratchpad at the bottom of the grid for rough work.

Three 'Visual Aids' are provided -

Color all occurrences of the selected number.
Show possible candidates of a cell in a box in each selected cell.
Show possible candidates of the current cell in a panel at the bottom of the grid.

Experimental Run -

The user may experiment with a certain 'line of thought' while retaining the current state in a store. This is done by invoking the 'Start an experimental run' feature. If the entries are correct, the user can confirm the run or if not, reject it and start over from the last correct state.

The status bar shows the time taken for solving or creating. It also provides feedback such as error messages or reasons for the 'Assist Solve' process.
