Solve puzzles using clues

Nonogram Atelier uses numerical runs around a grid to reveal a picture. Hitori starts with repeated numbers inside the grid and adds adjacency and connectivity rules. In Futoshiki, row and column constraints combine with inequalities between cells. Check the consequences of a mark or candidate rather than treating all three grids as the same puzzle.

A sequence or an opponent’s reply

Tower of Hanoi asks you to move smaller disks aside before moving a larger one. Four in a Row asks you to anticipate a reply on a board where pieces fall into columns. One is a solitary rearrangement problem; the other is a turn-based contest.

Move through a spatial problem

Fifteen Puzzle asks you to arrange numbered tiles around an empty space. Each slide changes which move is available next, so plan a sequence instead of moving one tile without considering the others.
