Before you place a bet
- Check that betting is legal where you live and that you are over the minimum age, which is 18 in most countries and 21 in many US states.
- Convert the odds into an implied probability so you know what the price is really saying.
- Read how the market is settled: extra time, retirements, dead heats and void legs all change what you get paid.
- Decide your budget for the month and a fixed stake per bet before you look at any prices.
- Record every bet with the odds you took, so you can judge your results honestly later.

About SportBetTime
SportBetTime explains how sports betting works, market by market and sport by sport. Every guide shows the arithmetic behind its examples, so you can check a payout or a probability yourself rather than take our word for it.
We do not sell tips, we do not promise profits and we do not rank bookmakers on this site today. How we research, check and update articles is set out in our editorial policy. Betting should only ever be paid for with money you can afford to lose; our responsible gambling page lists warning signs and where to get help.
Frequently asked questions
Is SportBetTime a bookmaker?
No. We do not take bets or hold accounts. SportBetTime publishes guides about how betting markets and odds work.
Do you give betting tips?
Not at the moment. Our guides explain markets, settlement rules and pricing so you can make your own decisions. We never describe any bet as guaranteed.
Which odds format do your guides use?
All three. Most examples show decimal odds with fractional and American equivalents, and the guide to how betting odds work explains how to convert between them.
Is sports betting legal where I live?
It depends on your country, and in the US and India on your state. Check the law that applies to you and only use operators licensed where you live. Nothing on this site is legal advice.
