Help Center — Frequently Asked Questions
What is BonusBell?
BonusBell is an independent information service that helps you discover, compare, and track online gambling platforms across all 50 US states. We cover 220+ platforms across 10+ markets — including sportsbooks, casinos, poker, DFS, sweepstakes, social casinos, crypto platforms, horse racing, prediction markets, and more. BonusBell is NOT a gambling operator — we do not accept bets, hold funds, or operate games for real money.
Is BonusBell free to use?
Most of BonusBell is free forever with no account needed — 10 calculators, 16 practice games, the RNG Strategy Lab, Gambling Online 101 (44+ articles), and the 220+ Platform Discovery Engine. The Universal Bet Calculator & Optimizer is free with 1 game and 2 sportsbooks. A free account unlocks expanded Bet Calculator features, odds comparison, bet tracking, bonus alerts, and Bella AI (10 messages per day). Pro ($19.95/mo with a 7-day free trial, no credit card required) adds the full Odds Intelligence suite, Bonus Conversion tools, and unlimited Bella AI.
Which states does BonusBell support?
BonusBell supports all 50 US states. We automatically detect your state and filter platforms to show only what is legally available where you are. Each state has different legal markets — some have licensed sportsbooks, others have sweepstakes casinos, and many have both. Our state-specific filtering ensures you only see relevant platforms.
Do I need an account to use BonusBell?
No account is needed for most features — calculators, practice games, the RNG Strategy Lab, learning articles, and the Platform Discovery Engine all work without signing up. Creating a free account unlocks additional features like odds comparison, bet tracking, bonus alerts, and Bella AI. Pro features require a subscription.
How do I create an account?
Click "Sign Up" on the homepage or any page. Enter your email address and create a password. During onboarding, you will select your state so we can show you the right platforms. The process takes about 30 seconds.
What is the difference between Free and Pro?
No account needed: 10 calculators, 16 practice games, RNG Strategy Lab, Gambling Online 101 (44+ articles), 220+ Platform Discovery Engine, and the basic Universal Bet Calculator (1 game, 2 books). Free account: expanded Bet Calculator, odds comparison, bet tracking, bonus alerts, and Bella AI (10 messages/day). Pro ($19.95/mo, 7-day free trial, no credit card): full Universal Bet Calculator (6 games, 8 books, parlays, scenarios, deep links), Odds Intelligence Suite (+EV Finder, Arb Scanner, Middles, Low-Hold), Bonus Conversion Suite, Smart Alerts, and unlimited Bella AI.
What calculators are available?
BonusBell offers 10 standalone calculators: Parlay, Hedge, Free Bet Conversion, Parlay Hedge, Bonus Playthrough, Kelly Criterion, No-Vig Fair Odds, Risk of Ruin, Teaser, and Parlay Tax. Plus the Universal Bet Calculator & Optimizer which combines arbitrage detection, expected value analysis, odds comparison, hold calculation, and scenario modeling in one tool. All calculators are free, include "Show Your Work" step-by-step math, and have InfoTooltips explaining every input and output.
What is the Universal Bet Calculator & Optimizer?
The Universal Bet Calculator is an all-in-one betting analysis tool that finds arbitrage opportunities, calculates expected value, compares odds across sportsbooks, computes market hold percentages, and builds scenario matrices. The free tier supports 1 game and 2 sportsbooks. Pro unlocks 6 games, 8 sportsbooks, synthetic parlays, scenario analysis, and deep links to sportsbook bet slips.
What are the practice games?
We offer 16 free casino practice games — including blackjack, poker, roulette, craps, baccarat, video poker, and more — with built-in strategy coaching. All games use simulated currency with no real-money value. No signup required. They are designed to help you learn optimal strategy in a zero-risk environment before playing for real.
What is the RNG Strategy Lab?
The RNG Strategy Lab is a free tool with three tabs: a Provably Fair Verifier (verify crypto casino fairness using SHA-256 and HMAC), an RTP Simulator (run thousands of simulated spins to understand variance and return-to-player), and a Strategy Builder (test betting strategies like Martingale and D'Alembert without risking real money). It runs entirely in your browser using the Web Crypto API — no data leaves your device.
What is the Provably Fair Verifier?
The Provably Fair Verifier lets you independently verify that a crypto casino game outcome was fair. You enter the server seed, client seed, nonce, and result — the tool recalculates the expected outcome using SHA-256/HMAC cryptography and confirms whether the casino produced the correct result. This is a standard transparency mechanism used by crypto gambling platforms.
Are calculator results financial advice?
No. All calculators produce mathematical outputs based on the numbers you enter — they are informational tools, not recommendations. BonusBell does not recommend any specific bet, wager, or gambling action. Calculator results are subject to real-world execution risk including odds changes, bet limits, and account restrictions. See our Disclaimer for full details.
What is the Odds Intelligence suite?
The Odds Intelligence Suite (Pro feature) provides odds comparison across major sportsbooks, an Arbitrage Scanner that finds negative-hold opportunities across books, a +EV Finder that identifies positive expected value bets using sharp-line devigging, a Middles detector that finds line disagreements creating a window where both sides can win, and low-hold market identification. All tools include execution risk disclaimers.
How does arbitrage detection work?
Our Arb Scanner compares odds across multiple sportsbooks to find markets where the combined hold is negative — meaning you can bet both sides and lock in a theoretical profit regardless of outcome. However, arbitrage opportunities carry real execution risk: odds change rapidly, sportsbooks impose bet limits, accounts can be restricted, and bets can be voided. Theoretical profit is not guaranteed profit.
What is +EV betting?
Positive expected value (+EV) betting means finding bets where the true probability of winning is higher than what the odds imply. We calculate fair odds by devigging sharp sportsbook lines (like Pinnacle) and comparing them to other books. A +EV bet has a mathematical edge over time, but individual bets can still lose. Variance is real — +EV betting is a long-term strategy, not a guaranteed outcome.
Can I link directly to sportsbook bet slips?
Yes — Pro users can click through from our odds comparison table directly to a pre-populated bet slip at the sportsbook. This saves time when executing opportunities. Deep links are available for major sportsbooks and are automatically adjusted for your state. Always review the bet slip details before confirming any wager.
How often is odds data updated?
Pregame odds are sourced from The Odds API and updated every 5 minutes. In-game odds for active events update every 60 seconds. However, odds move fast and the prices shown on BonusBell may not perfectly match what the sportsbook shows — always confirm odds directly on the sportsbook website before placing any wager.
What is Bella AI?
Bella is BonusBell's AI assistant, powered by Google's Gemini language model. She can answer questions about gambling strategy, explain platform features, help you understand betting math, navigate the dashboard, and provide general guidance. Bella is available in the dashboard to both free and Pro users.
Is Bella always accurate?
No. Like all AI language models, Bella can produce responses that are incorrect, outdated, incomplete, or misleading. AI models can "hallucinate" — generating confident-sounding answers that are factually wrong. Always verify any specific claim, number, or strategy Bella provides against authoritative sources before acting on it. Bella is a helpful starting point, not a substitute for your own research.
What are the Bella usage limits?
Free accounts get 10 Bella messages per day with a conversation history of 10 messages. Pro subscribers get unlimited messages with a conversation history of 50 messages. You can clear your conversation history at any time from the chat interface.
How is my Bella conversation data handled?
Your messages and Bella's responses are processed via the Google Gemini API and stored in your account on Firestore. Conversation data is not used for AI model training or advertising. You can clear your chat history at any time, and all conversation data is deleted if you delete your account. See our Privacy Policy and Data Policy for full details.
How does platform filtering work?
BonusBell detects your state automatically using your IP address and filters our database of 220+ platforms to show only those legally available where you are. You can also manually select a different state in your settings. Platforms are categorized across 10+ markets including sportsbooks, casinos, poker, DFS, sweepstakes, social casinos, crypto, horse racing, prediction markets, and skill gaming.
What types of platforms do you track?
We track 220+ platforms across 10 market categories: Sportsbooks, Casinos, Poker Rooms, Daily Fantasy Sports (DFS), Pick'em platforms, Horse Racing, Bingo, Lottery, Prediction Markets, and Skill Gaming. Within each category, we cover licensed (state-regulated), social (sweepstakes model), and crypto platforms. Each platform listing includes available bonuses, state availability, and key details.
How do I claim a promotion?
Click on any platform or promotion to see full details and terms. Then use our tracked link to visit the operator's website and sign up. The bonus is typically applied automatically during registration or your first deposit. Always read the operator's full terms and conditions — wagering requirements, minimum deposits, and expiration dates vary by offer.
Are listed promotions verified?
We research and update promotion data regularly, but gambling platform terms change frequently — sometimes without notice. A promotion listed on BonusBell may have changed, expired, or been modified by the time you visit the operator. Always confirm current terms, bonus amounts, and eligibility requirements directly on the operator's website before claiming any offer.
How do I update my profile?
Go to Dashboard > Settings > Account to update your profile information including your display name and state. Changing your state will update which platforms are shown to you across the app.
How is my data protected?
We use industry-standard encryption (256-bit SSL/TLS), secure HTTP-only session cookies via Firebase Authentication, and strict Firestore security rules. We never sell your personal data to third parties. Payment processing is handled entirely by Stripe (PCI DSS Level 1 certified) — we never see or store your card numbers. See our Privacy Policy for full details.
How do I delete my account?
Go to Dashboard > Settings > Privacy and click "Delete Account." This action is permanent — all your data including bet history, preferences, Bella AI conversations, and account information will be deleted within 30 days. Self-exclusion records are retained permanently for your protection. You can also email privacy@bonusbell.com to request deletion.
What is self-exclusion and how does it work?
Self-exclusion lets you block yourself from accessing gambling-related content on BonusBell. You can choose a period: 24 hours, 7 days, 30 days, 90 days, 1 year, or permanent. Once activated, self-exclusion cannot be reversed early — this is by design to protect you. All gambling content will be hidden from your account for the duration. You can access self-exclusion from Dashboard > Settings or from our Responsible Gaming page.
Can I export my data?
Yes. You can request a copy of your personal data by contacting privacy@bonusbell.com. We will provide your data in a portable format within 30 days, as required by applicable state privacy laws (CCPA, VCDPA, and others).
Is gambling legal in my state?
It depends on your state and the type of gambling. Licensed sportsbooks are legal in 30+ states. Sweepstakes and social casinos operate legally in nearly all 50 states. Daily Fantasy Sports, poker, and other markets vary by state. BonusBell automatically filters to show only platforms that are legally available in your state.
