What you get

  • Three puzzle files: A4 and US Letter with four boards to a page, and one with a single board to a page for a tablet.
  • The answers in a file of their own, so they never come out of the printer with the puzzles.
  • Four boards to a page for printing, and a third file with one to a page — for a tablet, or for a board you can rest a hand on.
  • Every board also playable on this site, with its answer a tap away.

How hard are they

Every board here was graded by the reasoning it actually needs, and a solver walked each one to the end before it was kept. None of them needs a guess, and none of them needs a rule you have not been told.

First moves

Boards 1–16

  • 6 × 6Every board falls to “What the neighbours rule out”, “The last cell of a region” and “The one home for a digit”; seven of the sixteen need the third.

One step further

Boards 17–44

  • 7 × 7The same three moves, on every board; seventeen of the twenty-eight need the third.

A new move

Boards 45–80

  • 8 × 8A new move, once or twice a board: “The shared neighbour” — a cell touching every place a region has left for a digit cannot hold that digit.

Medium difficulty

Boards 81–120

  • 8 × 8“The shared neighbour” again, now three to twelve times a board.

Larger boards

Boards 121–160

  • 10 × 10“The shared neighbour” three to twelve times again; no board needs “The pair”.

Hard

Boards 161–200

  • 10 × 10“The pair”, on every board: once on sixteen of them, two to ten times on the rest.

Each name in quotation marks is a chapter of Suguru’s how-to-play page, worked through step by step on a small board:
