Double or Nothing

How to play · Cases

Open a case for a chance at one of the items inside.

  1. Choose how many Pick x1, x2 or x5 — each reel opens the case once and is charged the case price.
  2. Open the case Press Open case. Every reel spins and lands on a single item.
  3. Rarer means richer Rarer items are worth more but drop less often — see the exact odds under Drop chances.
  4. Keep or upgrade Wins go straight to your inventory. Sell them back for gems, or take them to Upgrade for a shot at more.

Every result is locked in before the animation starts — check any round with Provably fair.

How this drop works

When you open this case, the site rolls a single 8-decimal number between 0 and 1 — for example: 0.27162707.

Every item owns a fixed slice of that range. You win the item whose slice your number lands in.

This item's slice
0.00000000 – 0.02000000 = 2.00%
Once a roll's seed is revealed, you can recheck the result in the site's verifier.
