The game uses a third-person, side-scrolling and room-based perspective across stages inspired by Episodes I–VI. Objectives include reaching the end of each level, defeating enemies, solving character-specific puzzles, collecting studs, and finding hidden items.

Story levels can be replayed with unlocked characters in Free Play, allowing access to areas that were previously inaccessible. Character abilities such as lightsaber use, blaster fire, Force powers, small-droid access, and bounty-hunter equipment determine progression. The DS version also includes handheld-specific minigame content.

Collect studs while exploring instead of rushing through each stage. Break LEGO objects, inspect side paths, and remember locations that require an ability unavailable during the first story visit.

Replay completed levels in Free Play with suitable characters. Prioritize red power bricks and hidden minikits when you have access to the relevant abilities, then use the resulting extras to make later collecting and combat easier.
