Info

This is a construction method that can be applied to any types of puzzles. Here we will explain the one that has been used in OAPC series.

Instructions

You are given 4 grids and 5 puzzletypes. Match each grid with a different puzzletype and solve the puzzles. One puzzletype will be unused.

Islands: Create white areas, surrounded with blackened cells which are linked to a continuous wall. The numbers in the grid indicate the size of the corresponding white areas. The wall cannot form any 2x2 square. White areas may touch each other only diagonally.

Masyu: Moving between edge-to-edge neighbouring cells, draw a closed path that passes through every digit and doesn’t cross itself. The path must turn at every even digit, but can not turn immediately before or after. And the path can not turn at any odd digit, but must turn immediately before and/or after.

Minesweeper: Locate 21 mines (12 for the example) in the diagram. The numbers inside the grid indicate the amount of mines in neighbouring cells. The cells with numbers do not contain any mines.

Top - Heavy Number Place: Fill the grid with digits 1-5 (1-4 for the example) so that each digits appears exactly once in every row/column. Where the digits adjoin vertically, the upper digit must be bigger.

Tapa: Paint some squares black to create a continuous wall. Numbers in the grid indicate the length of black cell blocks on its neighbouring cells. Painted cells cannot form a 2x2 square or larger. There are no wall segments on cells containing numbers.
