Managing your casino activity should not mean handing your data to yet another third party. Every Spindex tool is built privacy-first: the calculation happens locally in your browser. Upload a CSV or type in your wagering data and nothing is sent to our servers, stored, or shared. No accounts, no tracking, no data collection - just tools that respect your privacy.
The suite covers four major platforms, each with its own hub tuned to that casino's VIP structure, bonus system and export format: Stake.com, Stake.us, Rainbet and Roobet. Pick your casino above to jump straight to its calculators.
The P&L Analyzer turns raw casino transaction history into a clear picture of where you actually stand. Upload your CSV export and the tool processes it locally to break down total wagered, total won, net profit or loss, win rate by game type, session-by-session results, and trend charts over time.
Knowing your true P&L is the foundation of playing responsibly. Casino interfaces show individual session results, not the big picture, so most players underestimate their total spend. The Analyzer aggregates everything into one view. Run it for Stake.com or Stake.us.
Every crypto casino runs a VIP program with its own tier thresholds, rakeback percentages and bonus formulas. Our calculators are built per platform so the numbers reflect the real structure, not a generic estimate. Enter your wager total and you get your current tier, progress to the next level, expected weekly and monthly bonuses, rakeback rate, and total estimated rewards.
Choose your platform: Stake.com VIP calculator, Stake.us VIP calculator, Rainbet VIP calculator, or the Roobet rakeback calculator.
For Stake.com and Stake.us we also break out the recurring bonuses. Enter your wagered amount for the period and your tier to see exactly what to expect: Stake.com weekly and monthly, or the Stake.us weekly and monthly calculators.
Provably fair gaming is one of the real advantages of crypto casinos. Before each round, the outcome is locked in by a combination of cryptographic seeds, so after the round you can prove the result was genuinely random and was not altered. Our verifier makes that easy: enter the server seed, client seed and nonce, and it independently recomputes the outcome. If it matches what the casino showed, the round was fair.
Verify any round and learn how the whole system works on the provably fair page.
Rainbet players get a few extras beyond the standard calculators. The Mines predictor visualizes safe-tile odds for the Mines game, and if you are weighing the casino up first, read the honest is Rainbet legit review or the US access guide and legal states breakdown for players in the States.
Most casino tool sites ask you to create an account, log in, or upload data that then lives on their servers. That is an unnecessary risk: your gambling history, wager volumes and financial data sitting on someone else's machine. Spindex works the opposite way. Everything runs in your browser with client-side JavaScript, your CSV is parsed on your device, results render with no server round-trip, and when you close the tab the data is gone. You can confirm it by watching your browser's network activity while a tool runs.
Spindex offers a free suite for crypto and sweepstakes players: a P&L Analyzer that turns a CSV export into a full profit and loss breakdown, VIP calculators that estimate your tier progress and rewards, weekly and monthly bonus calculators, and provably fair verification. Tools are built per casino for Stake.com, Stake.us, Rainbet and Roobet, each matching that platform's exact VIP structure and bonus formulas.
Yes. Every tool runs entirely in your browser. When you upload a CSV or type in your wagering data, nothing is sent to our servers, stored in a database, or shared with a third party. There are no accounts and no tracking. You can confirm it yourself by opening your browser's network tab while using any tool: you will see zero outbound data.
You export your transaction history as a CSV from your casino account and upload it. The Analyzer parses the file locally and builds a full picture: total wagered, total won, net profit or loss, win rate by game, session-by-session results, and trend charts over time. It supports Stake.com and Stake.us exports, with more casinos being added.
It estimates your current VIP tier, shows how much more you need to wager to reach the next one, and projects your expected rewards including rakeback, weekly and monthly bonuses. Each casino has its own calculator tuned to its real tier thresholds and reward rates, so a Stake.com estimate uses Stake.com's structure and a Rainbet estimate uses Rainbet's.
Enter your wagered amount for the period and your VIP tier, and the calculator returns the bonus you can expect along with the formula behind it. They are most useful for Stake.com and Stake.us players who receive regular VIP bonuses, so you can see what a given week or month of play should return before it lands.
Provably fair games decide each outcome from cryptographic seeds before you play, so the result cannot be changed after the fact. Our verification tools let you enter the server seed, client seed and nonce from a round and independently recompute the result. If it matches what the casino showed, the round was fair. Learn more on the provably fair page.
No. Everything is free with no signup, login or account. Open the tool you need, enter your data or upload a CSV, and get instant results. There are no usage limits, premium tiers or upsells. The tools are free because they introduce players to the wider Spindex slot-data platform.
Right now: Stake.com (crypto), Stake.us (sweepstakes), Rainbet (crypto) and Roobet (crypto). Each has a dedicated tools hub with calculators built for that platform. Support for Gamdom, Shuffle, BC.Game and Duelbits is in progress, so check back for new additions.
No. They help you understand and manage your play, not beat the house. The P&L Analyzer shows your real results, the VIP and bonus calculators help you capture rewards on activity you are already doing, and the verifier confirms fairness. No tool can change a game's built-in mathematical edge. Always gamble responsibly.
The tools are one side of Spindex. On the data side you can browse the slot demo and RTP database, track which games are running hot on the live hot slots board, watch the big wins feed, dig into game statistics, or compare welcome offers on the casino bonuses page.
These tools exist to help you understand and manage your gambling, not to encourage more of it. If your P&L trends down, treat that as a signal to slow down. VIP and bonus calculators help you capture value on play you are already doing, not a reason to wager more. Set deposit limits, never stake more than you can afford to lose, and if gambling is becoming a problem, visit our responsible gambling page for support resources.
