4th Nov 2025. I have changed the archive calendar to load puzzles into the player rather than going
straight to print. I may have fixed a bug with the current day's puzzle sometimes not saving progress.
I believe progress should be saved for older puzzles as well. Please let me know any knock on effects! Thank-you
Check out the new colour options - change to a black and white board.
Prefill notes and Auto Clear
- Prefill will place 1 to 6 in any empty cell. Useful at the start of play of you prefer to remove candidates rather than add them. Optional to use.
- Auto Clear will remove notes when you place a solution in a cell or when turned on for the first time. You can toggle on and off if you want a temporary clear-off. Optional to use.
- Good idea or bad? Let me know andrew@str8ts.com
- You can now navigate with the arrow keys
- 0, Del or Backspace will delete all notes
- N or space = Toggle Notes. On a single 'note' will toggle that number large
- Buttons with an underscore mean keyboard activation with that letter
- CRTL+z = undo, CTRL+y = redo
- Popups can be dismissed with 'Enter'. 'Escape' for cancel

How to play Mini Killer Sudoku
Mini Killer is based on 6x6 Sudoku, so ultimately you need to place the numbers 1 to 6 on all the cell so that 1 to 6 is unique in every row, column and box. However, you will have few, if any, completed cells in Killer. Instead, groups of cells form blocks or 'cages' - and the clue is the sum of the solutions to those squares. Each 'cage' is shown by a color or dashed line. A clue of '3' in a two-cell cage means those cells will contain 1 and 2 - but it won't be obvious which way round at the start of the puzzle.Combinations are key to this puzzle at the outset, but all Sudoku strategies still apply.
