Extension summary

Analyze keywords

NEW updated version for 2015: a new endless list of beautifully symmetric boards, a new highly readable handwriting font, and a bit more challenging levels.

Heidi's Sudoku is different from other sudoku programs because it gives good hints. It can gently guide you out of a jam without giving away the whole puzzle.

The Hint button highlights a few squares to concentrate on. Things are not totally given away, but if you hold down ctrl when clicking Hint, you will get more of an explicit hint.

You can select Colors to see which parts of the board should be easiest to figure out first, and which parts are really hard and should be left to the end.

Don't give up after you have hit a dead end in a puzzle. Use the Check button for a tip on whether you've made a mistake, and hold ctrl to see where it might be.

More features:

Switch between puzzles at your leisure. Learn to see tricks like naked pairs, hidden sets, xwing, ywing, swordfish, etc. Use mouse input or keyboard shortcuts.

User reviews

No adds. Supports note marks. Verifies guesses to ease frustration. Works with touchscreen or mouse. Contrast could be better on my old ASUS Windows laptop - converted to Chrome OS, but that is a nit.

Works well with many puzzle to choose from. The soft hints are very good. Thanks

Best sudoku game I have used but it is aggravating to be sent back to puzzle number one or two when you are trying to advance to number three hundred and something.
