What Spindex is, who it is for, and what it costs.
Spindex is a real-time analytics platform for crypto and sweepstakes casinos. It tracks live slot wins, hot-slot heat scores, big wins and streamer sessions across Stake.com, Stake.us, Rainbet, Roobet, Gamdom, Duelbits and Shuffle, and pairs that data with free calculators and analyzers (P&L, VIP, weekly and monthly bonus, Mines predictor, seed analyzer, plus sports tools like no-vig, arbitrage, parlay and Kelly). The goal is simple: give players real numbers instead of guesswork.
Yes, completely. Every tracker, calculator, analyzer and data feed is free with no paid tiers. Creating a free account unlocks the fresher 1-hour timeframe on Hot Slots and Big Wins and lets you save favorites, but everything else works without signing in.
Live slot and win tracking runs for Stake.com, Stake.us, Rainbet, Roobet, Gamdom, Duelbits and Shuffle. Dedicated tool suites exist for Stake.com, Stake.us, Rainbet and Roobet today, with Gamdom, Duelbits and Shuffle toolkits on the roadmap.
No. Spindex is independent and built for players. Some pages carry affiliate links or referral codes that help fund the project, but Spindex does not own, operate or manage any casino it tracks, and the data and rankings are not influenced by those partnerships.
How the real-time slot, big-win and streamer feeds work.
Hot Slots ranks every tracked game by how far it is deviating from its own 30-day baseline, not by popularity. The engine rescoring runs every 60 seconds using win rate, multiplier velocity, big-hit frequency and bet volume, so games paying out above their normal rhythm rise to the top.
1-hour shows what is spiking right now, best for short-term streaks. 24-hour smooths the noise and surfaces sustained heat. 7-day highlights games trending up across the week. The 1-hour view needs a free account; 24H and 7D are open to everyone.
Big Wins surfaces the largest verified slot wins across every tracked casino, ranked by multiplier so a 5,000x hit on a $1 bet sits alongside a 5,000x on $100 - quality of the win, not the stake behind it. The 1-hour view is account-gated; 24H and 7D are public.
A curated feed of the biggest verified slot wins from top crypto-casino streamers. Filter by streamer, sort by multiplier or win amount, and jump straight to the replay clip when one is available.
The free per-casino toolkits Spindex publishes.
Dedicated suites for Stake.com, Stake.us, Rainbet and Roobet. Across them you get P&L analyzers, per-casino VIP calculators, weekly and monthly bonus estimators, the Rainbet Mines predictor, a provably fair seed analyzer and referral-code pages.
Both include a P&L analyzer for your CSV transaction exports, a VIP calculator covering the full tier ladder with level-up estimates, weekly and monthly bonus calculators, and a seed analyzer for Stake Originals. The Stake.us versions add separate Stake Cash and Gold Coin handling to match the US sweepstakes model.
Rainbet includes the Mines predictor with a live EV ladder, a VIP calculator across all 25 levels, a site review, and US access and legal-states guides. Roobet includes a VIP calculator covering all 31 levels with wager-to-next-tier and rewards at each milestone. More Rainbet and Roobet tools are in development.
What each tool does and how to use it.
Upload your casino transaction CSV and it instantly computes total P&L, ROI, monthly breakdown, per-currency stats, win rate, streaks and best and worst days. The Stake.us version splits Stake Cash from Gold Coins. Everything runs in your browser, so the file never leaves your device.
Enter your total wagered (or current level and progress) and it shows your exact tier position, the wager needed to reach the next level, and expected level-up rewards. Available for Stake.com, Stake.us, Rainbet and Roobet, each using that casino's own tier structure.
Both use a community-verified model built on the same inputs the casino's bonus engine uses: VIP level, wager volume for the period, profit or loss, and game-type weighting. You get a low / mid / high estimate so you can plan sessions before the bonus drops.
It is a decision tool, not a cheat. Set your grid and mine count and it highlights favorable tiles with conservative, balanced and aggressive cashout presets plus a live EV ladder. It cannot see through a hashed server seed - that is mathematically impossible - it simply shows the expected value at each step so you cash out on math, not impulse.
A provably fair verification tool. After you rotate your seed pair, paste the revealed server seed, your client seed and a nonce range, and it replays exactly what would have happened across thousands of rounds for the supported Stake Originals. Useful for verifying fairness and studying variance, and it runs fully client-side.
How RTP, heat scores and our metrics are measured.
RTP (Return to Player) is the theoretical percentage of wagered money a slot returns over the very long run. A 96% RTP game returns about $96 per $100 wagered across millions of spins. It is a statistical average, not a promise for any single session.
Many providers ship a game in several RTP versions, and each casino chooses which one to run. That is why the RTP at your specific casino matters - some run lower-RTP builds that quietly cut your expected return. Spindex shows the certified provider RTP so you can compare.
It is a statistical deviation metric, not a popularity count. Every tracked slot is scored every 60 seconds against its own 30-day baseline using win-rate trend, multiplier velocity, big-hit frequency and recent volume. A game can be wildly popular with a low heat score, or obscure with a high one.
A composite 0-100 score that blends five signals: crypto market regime, volume versus baseline, multiplier heat, market breadth (how many games are running hot) and an over-extension component. It is snapshotted hourly with a 24-hour sparkline so you can read the trend, not just the current number.
Sign-in, what is gated, and how your data is handled.
Only two things: the 1-hour timeframe on Hot Slots and the 1-hour timeframe on Big Wins. Both unlock the moment you sign up. Every calculator, analyzer, the streamer feed and all 24H and 7D data are open to everyone.
Yes. Both run entirely in your browser. Your seeds, transaction CSVs and any uploaded data are never sent to our servers - you can confirm it in your browser's network tab. Processing happens locally on your device.
A free account stores only what is needed to run your favorites and unlock the 1-hour views. Spindex does not sell your data. You stay in control of what you save.
Yes. Use the form on the Contact page or email contact@spindex.net, and we will remove your account and associated data within 7 days.
