The Grinch explores several areas of Whoville from a third-person perspective. Each area contains objectives such as finding items, activating mechanisms, avoiding or distracting enemies, and causing enough mischief to advance.

Progression is based on completing tasks and collecting objects rather than on a conventional experience system. The Grinch can use jumps, attacks, sneaking, and special gadgets to navigate the levels. Some sections emphasize platforming, while others require searching rooms and solving simple environmental puzzles.

Search each area thoroughly before moving on. Important objects and objectives are often placed away from the most direct route, and collecting useful items early reduces backtracking.

Use stealth or distractions when several enemies are present. Save stronger gadgets for encounters that block progress, and learn the timing of jumps before attempting longer platforming sections.
