Proof of Play
Mining Badge
Mining Badges are your mining tool within Proof of Play. By staking CR, you upgrade your badge and improve your chances of receiving higher-tier Mystery Boxes, which are more likely to contain CR.
Mining Badges improve your odds. They never improve your ability to win.

Upgrading Your Mining Badge
Every player starts with the baseline Mystery Box odds. To improve them, stake CR and upgrade your badge: the stronger the badge, the better your chances of higher-tier boxes.

Staking also commits CR back into the Clash Rush economy.
Mining Badge Tiers
Your badge tier depends on how much CR you stake. Each tier raises your odds of a box above the baseline tier.

What Mining Badges Actually Change
Mining Badges affect which Mystery Box tier you're likely to receive. They do not:
- Guarantee a higher-tier box
- Guarantee CR inside a box
- Increase CR emissions
- Create additional CR
- Improve competitive gameplay
Mining Badge Flow
- 01Higher CR Stake
- 02Higher Mining Badge
- 03Better Mystery Box Tier Odds
- 04Better CR Probability
Your badge doesn't increase the amount of CR you receive. It improves your chance of a better box, and the box tier sets the probability of discovering CR.
