Use the clues to uncover the body of a snake, given the location of the head and tail. The body is a 1-cell wide path that travels only in orthogonal directions and may never touch itself, even diagonally.

Find and shade all duplicate numbers in rows and columns, leaving only unique digits. No shaded cell may be adjacent to another, and unshaded cells must form a contiguous area.

Find a hidden fleet of single-cell boats. Lighthouses reveal all boats in their row and column. Boats may not be adjacent to other boats or lighthouses in any direction.

Place numbers from 1 to N (N being the size of the grid) such that there are no duplicates in rows or columns. Each brick must have both an odd and an even number.

Using the clues given, mark all cells containing mines. Numbers indicate how many mines surround them. Unlike the computer game, you get to see all the clues when you start. Interestingly,

Place one tetromino in each region such that all of them are orthogonally contiguous, no tetrominoes of the same type are adjacent, and no 2×2 area of cells is covered.

Place a fleet into the grid using the clues around the edge. Ships may not touch each other in any direction.

Divide a grid of numbers by locating the correct position for all possible dominoes in a given set.

Place diagonal lines in every cell so that there are no closed loops. Circled numbers indicate how many lines touch that intersection.

Place a single star and cloud in each row and column to correctly illuminate the moons.
