Frequently Asked Questions

Spindex is a real-time slot tracking platform that monitors performance data across multiple crypto casinos. We track live wins, calculate heat scores, and provide tools to help you make informed decisions about which slots are paying out.

Yes! All core features including the slots database, live tracker, big wins feed, and RTP data are completely free. Some features like favorites require a free Discord sign-in.

We currently track data from Stake.com, Roobet, Gamdom, Duelbits, Rainbet, BC.Game, and Shuffle.com. We're always looking to add more.

RTP (Return to Player) is the theoretical percentage of wagered money a slot returns to players over time. For example, a slot with 96% RTP will theoretically return $96 for every $100 wagered over millions of spins.

Many slot providers offer multiple RTP versions of the same game. Casinos can choose which version to offer. This is why checking the RTP at your specific casino matters - some casinos run lower RTP versions that significantly reduce your expected returns.

Our RTP data is verified through game info screens, support chats, and community reports. We cross-reference data across multiple sources. If you spot an inaccuracy, please let us know via the Contact page.

The heat score is our proprietary metric that combines recent win rate, average multiplier, big win frequency, and betting volume to indicate how hot a slot is performing right now. Higher scores mean the slot is paying out more than usual.

The Seed Analyzer is a provably fair verification tool for Stake Originals. After rotating your seeds on Stake, you can input your server seed, client seed, and nonce to verify past game results and simulate what would have happened across thousands of rounds.

The VIP Calculator helps you estimate your current VIP level and the cost to reach the next level on Stake.us or Stake.com. It factors in the RTP of different game types to show you the true cost of leveling up.

Yes. The Seed Analyzer runs 100% client-side in your browser. Your seeds and game data are never sent to our servers. Everything is processed locally on your device.

Discord sign-in is only required for features that need to save data to your account, like favorites. All browsing, searching, and tool usage is available without signing in.
