Donkey Kong (1994)

The familiar arcade opening gives way to compact key-and-door puzzles where an enemy, ladder or movable platform has a specific job. Mario's expanded movement makes a small space rich in possible routes rather than simply longer. A stage supplies a satisfying little problem before the next interruption. This is the 1994 Game Boy game, not the original arcade release. Some screens still demand quick execution after the solution is clear, so it is more active than a quiet block-pushing puzzle.
