Short rules for each game and longer guides for the moments where people get stuck.

Guides

Rules in brief

• Sudoku

  Every row, column and 3×3 box ends up with the digits 1 to 9, no repeats.

• Kakuro

  Digits 1–9 go in the white squares; each across or down run adds up to its clue and never repeats a digit.

• Skyscrapers

  Heights 1 to N fill each line once; an edge number says how many buildings are visible from there.

• Fifteen

  Move tiles into the gap until they read in order, with the gap finishing bottom right.

• Mine Finder

  Uncover all the safe squares; each number counts the mines around it, and logic alone is enough.
