Lums are the primary currency and collectible in Rayman Origins. While collecting a certain amount is often required to unlock new levels, striving for 100% Lum collection in every level is a significant side activity. Collecting 100 Lums in a single level transforms the 'Lum King' into a 'Lum Queen' for a short period, doubling the value of all Lums collected during that time. This is crucial for reaching the higher Lum thresholds.

Why Collect Lums?
- Unlock Levels: A minimum number of Lums are required to unlock new levels and worlds.
- Unlock Characters: Collecting enough Lums contributes to unlocking new playable characters and costumes.
- Score & Medals: Your total Lum count contributes to your overall score and the medals you earn at the end of each level (bronze, silver, gold).
- Electoons: In many levels, reaching specific Lum thresholds (e.g., 50 Lums, 100 Lums) will award you an Electoon.
Tips for Lum Collection:
- Explore Thoroughly: Many Lums are hidden in secret passages, behind breakable walls, or in areas that require precise platforming.
- Use Charged Attacks: Charged punches can break certain obstacles that hide Lums.
- Look for Lum Chains: Often, a trail of Lums will lead you to a hidden area or a challenging platforming sequence.
- Replay Levels: Don't be afraid to replay levels multiple times. Once you know the layout, it's easier to plan your route for maximum Lum collection.
