You are rewarded for participating in challenges. Rewards are given when challenges have ended. We give Fills, Swaps, and Keys. Here is the breakdown for when we give these rewards:
- A Fill every 4th challenge that has ended.
- A Swap after every 6th challenge that has ended
- A Key every 8th challenge that has ended
These rewards are given out independent of each other. The count is from when the last time each of the rewards has been given. That means you may receive one or more of the rewards in a given challenge or none.
The ratio of how often the rewards are given are based on general participation in challenges and may change in the future.
