Frequently Asked Questions
Are digital pack opening sites considered gambling?
While legally classified under mystery box, sweepstakes, or entertainment commerce in most jurisdictions, their core mechanic relies on randomized chance with variable financial returns. We recommend treating all pack ripping strictly as entertainment and never as an investment vehicle.
What is a "Buyback Haircut" and why does it matter?
When you unbox a card worth $100 Fair Market Value (FMV) on a site, the platform offers an instant sell-back option. A platform with a 6% buyback fee (like Courtyard) gives you $94 cash. However, platforms with 20% to 25% haircuts only pay $75 to $80. Choosing low-fee sites saves you substantial capital over time.
How do I verify if a pack opening is Provably Fair?
A provably fair platform publishes a SHA-256 server seed hash before you purchase or rip the pack. After the pull is revealed, the unhashed server seed and nonce are revealed, allowing you to run the mathematical calculation in any third-party SHA-256 calculator to verify the outcome was predetermined and tamper-proof.
