New to online betting or just tired of confusing jargon? Our betting glossary explains casino and sports betting terms in plain language, with short, practical examples you can use when reading terms and conditions.

Online casinos and bookmakers love small print. Wagering requirements, excluded games, minimum odds and RTP can make it hard to see if a bonus or bet is worth it. BetToolKit gives you clear, numerical answers so you can make better decisions.
See required turnover, expected loss ranges and realistic profit instead of vague marketing promises like “up to 500% bonus”.
Lightweight layout that works on desktop, tablet and phones - ideal when you are browsing bonuses or odds in real time.
Open a tool, enter your numbers and go. No registration, no email spam, no tracking-heavy dashboards.
Paste the bonus size, deposit and rollover multiple into the wagering calculator to see how much you realistically need to bet. If the required turnover looks insane for your bankroll, it might be better to skip the offer.
Use the bet profit calculator to compare different markets and odds instantly. When you spot big discrepancies between bookies, the surebet calculator helps you check if there is a guaranteed-profit arbitrage.
