Sudoku Dragon Program Update 13

Version 2.6 Build 13 - Sudoku puzzle solving

Here is the detailed technical list of changes that has been made to Sudoku Dragon since the last update.

Release date 1st November 2005.

It contains the following major new features:

  • The last square allocation is highlighted with a different background color in the grid
  • The large grid 16x16 offers both hexadecimal and numeric display options
  • All generated puzzles can have an optional Sudoku Stripe incorporated

It contains the following enhancements to existing functionality:

  • A confirmation prompt is required to overwrite any of the initially allocated squares
  • First contribution triggers special registration prompt message
  • The contribution screen is automatically closed when the contribution has been successfully submitted
  • Icon colors have been changed to blue/yellow
  • Initial square allocations are given an 'initial square' reason in the details screen rather than left blank
  • The cursor now turns to an I-beam over the selected grid square when the grid has input focus

The following fixes have been applied:

  • The possibility bar used column-row display order for region co-ordinates
  • The update information button had no effect on the Upgrade screen
  • The puzzle timer is reset when the initial grid square allocation is saved
  • If the header row/column is switched off then the program may crash in print preview mode
  • The print-out may not use a white background for the grid description and annotation listing
  • The hint display did not use the currently allocated background color for square display
  • The print option for possibilities in unallocated squares was displayed the wrong way around
  • If a blank game is initially saved and the allocation list is enabled then undo may cause program to crash
  • When open rather than generate a new puzzle the input focus flashing cursor was not indicated in the grid
