Skyscraper: Enter a number into each square, which represents the height of a skyscraper. Each row and column of each grid must contain all different numbers. A number outside the grid indicates how many skyscrapers are visible from that direction, where taller skyscrapers block the view of shorter ones behind them.

Kakuro: Enter digits 1–9 into the white squares in such a way that every horizontal and vertical contiguous run of digits has the sum indicated before it. The digits in each such run must be all different.

Akari-Tents hybrid with diagonals: Place lamps in some white squares in such a way that every white square is illuminated and no lamp directly shines at another. Lamps shine in all horizontal, vertical and diagonal directions, even diagonally across corners of black squares, but not diagonally between two black squares (nor right through black squares). There is exactly one lamp plugged into each outlet (circle). Lamps must be orthogonally or diagonally adjacent to their corresponding outlet (and may also be adjacent to another outlet that has its own lamp elsewhere).

Nonogram: Shade some cells in the grid such that the clues outside the grid describe the lengths of all contiguous runs of shaded cells in that row or column in the correct order. The numbers 1–7 have been replaced with seven different items selected from a list of confectionery brands. The row clues use a different permutation of the numbers 1–7 than the column clues (but some sweets may or may not have the same number in both permutations).

Battleship: Place the ships into the grid in such a way that they do not touch each other, even diagonally. The numbers outside the grid show the number of ship pieces in each row or column.

Fillomino: Enter digits into the empty cells in such a way that every orthogonally connected area of the same digit has the exact size given by the digit. Same sized areas cannot touch each other orthogonally.

Hashiwokakero

Connect all the islands (the circles with numbers) with horizontal or vertical bridges.

Each island must have as many outgoing bridges as the number in the island.

Each pair of islands can only have a maximum of two bridges between them.

Bridges cannot cross each other or go over other islands.

Masyu

Draw five loops — one per grid — with lines along the grid lines. All black and white circles must have a part of the loop pass through them.

A white circle indicates that the loop passes straight through it and makes an immediate 90° turn on either side of the circle (or both).

A black circle indicates that the loop makes a 90° turn on it and goes straight on both sides of the circle.

Lines cannot form any junctions (crosses or T-junctions).
