Mystery Box


Mystery Box is a Counter-Strike-style case opening where you spend XCredits to open a themed box and win a real Splinterlands card, delivered straight to your account.


How it works:

  1. Go to the Mystery Box page
  2. Pick one of the 20 themed boxes (Tidebreaker's Vault, Sunspire Treasury, Chaos Crucible, and more)
  3. Review the box's possible rewards, their values, and your odds — every box shows exactly what you can win and how likely each card is
  4. Choose which of your registered accounts should receive the card
  5. Click Open, watch the reel spin, and see where it lands
  6. The card you win is sent to your account automatically

The odds are transparent:

  • Box prices range from 5,000 to 50,000 XCredits (XCredits are 1:1 with DEC).
  • Boxes use varied prize structures: some are jackpot-heavy, some use classic odds, and some spread more probability through the middle of the prize table.
  • The average reward is 85% of the box price in card value — a fixed 15% house edge, shown on each box.
  • The full probability of every card is displayed before you open. Nothing is hidden.

Notes:

  • You need to be signed in and have a registered Splinterlands account to open a box (that's where the card is delivered).
  • Each box can be opened only once — once someone opens it, it shows as Opened. New boxes will be added from time to time, so check back.
  • Each XBOT user can purchase one Mystery Box every 24 hours. After a purchase, the page shows the remaining cooldown.
  • If two people try to open the same box at the same moment, only one opens it; the other isn't charged.
  • In the rare case the exact card you win just sold out, the full box price is automatically refunded and the box reopens.
  • If delivery is briefly delayed, don't worry — the win is recorded and the card is delivered as soon as possible.
