Brain Burst
Earned by winning a Brain Boost mini-game.
How to earn one
Win any of the 9 Brain Boost mini-games and your besti earns a Brain Burst. You can play any game, any time, but you only earn a new Brain Burst if your pet doesn't already have one active. Keep playing while one's already glowing and it's just for fun; no second Burst until it clears.
Of the three Burst types, Brain Burst is the smallest single boost. But games are quick, and there are nine of them to pick from.
Feed it, or convert it
Once you've got a Brain Burst, you choose: feed it to your pet for growth, or convert it to Sparks and spend them in the Spark Store.
Feed
An instant push toward your pet's next stage. Growth from Bursts is capped at 10% of the current stage per day, shared across all three Burst types.
Convert
Trade the Burst for Sparks, spent on cosmetic extras (world effects and wearable items) in the Spark Store instead.
