Strategy guides for the games we host — written and illustrated by the people who built them. No filler, no recycled listicles: each guide teaches one technique properly, with hand-built diagrams you can check against a real board. Start with the overview guide for your game, then go deeper technique by technique.
Sudoku
From your first Easy board to Extreme puzzles that need chained deductions. The overview guide covers eight techniques; the individual guides work through each one with diagrams.

Sudoku Strategies, Explained with Diagrams
A visual guide to eight techniques — from last remaining cell to box/line reduction — each with a worked diagram. Solve hard puzzles without guessing.
-
Last Remaining Cell
The first technique every solver learns: when a row, column or box has one empty cell left, the digit is forced.
-
Cross-Hatching
Scan a digit across intersecting rows and columns to corner the only cell it can occupy in a box.
-
Hidden Singles
A digit with only one legal home in a unit — hidden among other candidates, but forced once you look.
-
Naked Pairs
Two cells locked to the same two candidates eliminate those digits from the rest of the unit.
-
Hidden Pairs
Two digits confined to the same two cells — everything else in those cells can be erased.
-
Naked Triples
Three cells sharing three candidates between them, and the eliminations they force across the unit.
-
Pointing Pairs
When a digit in a box lines up on one row or column, it sweeps that digit out of the rest of the line.
-
Box/Line Reduction
The mirror of pointing pairs: a digit confined to one box within a line clears the rest of the box.
Minesweeper
Minesweeper is deduction, not luck. These guides teach you to read numbers together instead of one at a time — and what to do on the rare boards where a guess is forced.

2048
