The Dice Road starts over every two weeks. Each two-week cycle is called a run.
As your points grow, you reach new reward tiers. Every tier has a free reward, and the Golden Pass (Get Pass on the Dice Road) adds a second reward to every tier.
Rewards you reached but did not collect are given to you automatically when the run ends (Golden Pass rewards only if you had the pass). Then your points start over for the next run.
