In Disney Infinity 1.0, all Sparks are the same bluish-white color and are the method by which characters gain experience.
Additionally in Disney Infinity 3.0:
- When opening a surprise Gift in the Toy Box Hub, if the Toy to be awarded has already been unlocked in the Toy Store, blue Sparks are awarded instead.
- When Farming, harvesting Flowers and Weeds will award blue Sparks.
Some Ability Discs affect Sparks, either by granting a chance for increased Sparks, or increasing the pick-up radius. It is possible to use one of each type at the same time to help a character earn more experience.
There are a number of ways to generate additional sparks in the Toy Box. One way is through Farming (planting seeds and harvesting Flowers or Weeds); however, this is only available in the Disney Infinity 3.0 Edition. Another is to build a "Spark generator" by placing and connecting a number of Toys in such a way to continually generate and automatically defeat Enemies. Larger/stronger Enemies that are normally harder to defeat (e.g. the Tank Omnidroid) typically produce more Sparks than smaller/weaker ones.
