Yes – the result of every pack and Single Pull is locked in before the animation begins. The animation only shows you what was already decided.
What actually happens when you click Open or Spin
Your Coins are deducted.
Our server combines the server seed, your client seed and the nonce and computes a winning ticket for each card slot. This happens in a fraction of a second.
The result is saved to your opening history together with the seeds used.
Only then does your browser play the animation, which is built to end on the card you already won.
Nothing in step 4 can change the outcome. If your internet drops or you close the tab mid-animation, the cards are still in your Backpack – check Profile → Openings.
"But it stopped one card before the big hit!"
We know that feeling. The spinner is designed to be exciting, and that includes slowing down near valuable cards. Those near-misses are purely visual: the winning card was fixed before the spinner started moving, and the animation is simply the route it takes to get there. The odds of each card are exactly what's printed on the collection grid, no more and no less.
How to check for yourself
Open Profile → Openings and click Details on the opening.
Note the Server Seed, Client Seed, Nonce and Winning Ticket.
Click Verify Fairness (or use any HMAC-SHA512 calculator) to recompute the ticket from the seeds. It will match.
Hash the revealed server seed with SHA-256 and compare it to the hashed server seed that was shown before the opening. It will match too – which proves the seed wasn't swapped after you spun.
The Provably Fair article walks through this in detail.
