Sudoku is a favourite brain game for older adults because it is calm, quiet and just challenging enough. PuzzleCraft keeps it simple: big squares, a large number pad, and an easy level that never needs tricky techniques.
Prefer paper? Use Large Print to print one big puzzle per page, with the answer on a separate sheet. Activity coordinators in care homes can print 2 or 4 per page for group sessions.
Play right in the browser with a big touch-friendly number pad or your keyboard. Turn on Notes to pencil in candidates, and they disappear automatically when you place a number. Undo, redo, an eraser, row/column/box highlighting, matching-number highlights, optional mistake checking and a pausable timer are all built in. Your progress saves on your device, so you can come back to an unfinished grid later.
Stuck? The Hint Assistant teaches instead of just giving answers. The first hint points to the area to look at, the second names the technique, the third highlights the exact squares and explains the logic in plain English, and only the fourth fills in the number. Hints used appear on your results card.
