Sports betting is, in its simplest form, placing a wager on the outcome of a sporting event. Whether it’s picking a football team to win or predicting how many sets a tennis match will go to, it all boils down to making a choice based on what you think will happen.
It’s different from casino-style games - here, your decisions are based on real-world events, stats, and team performance. You’re not playing against the house, but rather placing bets based on your knowledge or instinct.
In the UK, sports betting is a legal and regulated activity, governed by the UK Gambling Commission since 2005. This means platforms like Casumo operate under clear rules that protect players and ensure fairness.
Some of the most popular sports to bet on in the UK include:
No matter the sport, the principle stays the same: you're predicting an outcome, and if it happens, your bet settles based on the odds.
Odds are a representation of probability. They show how likely something is to happen and what your return could be if it does.
In the UK, the most commonly used format is fractional odds. For example, odds of 2/1 mean that for every £1 you stake, you’ll receive £2 back if your bet comes through (plus your original £1).
There are also decimal and American formats, which some platforms offer for preference. But no matter the format, the maths behind it stays the same: the higher the odds, the less likely the outcome, and vice versa.
Odds aren’t fixed. They can shift depending on things like team news, betting patterns, or live match developments. That’s why timing and awareness can play a role in how you place your bets.

The UK’s number one betting sport. From the Premier League to lower divisions, there are fixtures almost daily with betting options including match results, goals, scorers, corners, and more.
A long-standing part of UK culture. With events running daily and big calendar moments like Cheltenham and Royal Ascot, horse racing remains one of the most diverse betting sports available.
With Wimbledon at the heart of the UK season, tennis offers year-round betting options across ATP and WTA tours. Live betting is especially popular due to the match’s fast pace.
Cricket & Rugby
From the Ashes and World Cup to club-level matches, cricket and rugby have a strong presence in UK betting markets. You’ll find a mix of short-form and long-format events.
There’s more than one way to place a bet. Whether you're dipping your toes into your first football punt or building out a weekend accumulator, it helps to understand the different types of sports bets available.
Some bet types are perfect for beginners. Others involve more selections, combinations, or long-term predictions. The good news? You don’t need to know them all at once. Just start where you’re comfortable, and build from there.
If you’re new to sports betting, these are the easiest bets to wrap your head around:
These bets are common across top UK sports like football, rugby, and cricket. They’re simple, straightforward, and a good place to begin.
Once you’re comfortable with singles, you might want to explore combination bets where you group multiple selections into one bet. Here’s how they work:
Combination bets are popular for weekend football fixtures or horse racing picks. Just keep in mind, the more selections, the less room for error.

Starting out doesn’t have to be complicated. Whether you're placing your first ever bet or just new to Casumo, we’ve made sure the process is clear, secure, and built around responsible play from the very first click.
Here’s a step-by-step guide to help you get going with sports betting in the UK safely, confidently, and all on your terms.
Before anything else, make sure you're betting with a site that's fully licensed by the UK Gambling Commission (UKGC). This means it’s held to strict rules around fairness, player protection, and data security.
Casumo is proud to be a UKGC-licensed operator, with our licence number listed publicly and our platform built to protect players. From encrypted payments to dedicated responsible gambling tools, every part of our setup is designed to keep your experience safe.
Signing up takes just a few minutes. You’ll need to provide some basic details like:
To meet UK laws, you’ll also need to verify your identity before you can start betting. That usually means uploading a photo ID and proof of address. It's a simple step and helps keep everyone safe.
Once your account is set up, you can fund it using trusted UK payment methods, including:
Minimum deposit amounts will be clearly displayed, and all transactions are protected by SSL encryption. You can also set deposit limits from the start to help manage your activity.
Don’t forget: a welcome offer may be available when you make your first deposit. Check the full terms before you opt in.
Ready to give it a go? Here’s what to expect:
Once placed, you can track your open bets in your account and even use live features like cash out where available.
Let’s be honest: there’s no magic system that guarantees outcomes in sports betting. But there are some strategies that can help you bet more mindfully, manage your activity, and get more from the experience, especially if you're in it for the long run.
From setting limits to spotting patterns, this guide shares practical ways to stay in control and bet with a bit more intention.
Just starting out? These tips are especially helpful for beginners looking to build solid habits from the start:
These tips won’t guarantee outcomes, but they’ll make your betting experience more measured and considered.
Think of your bankroll as your total betting budget, a set amount of money you’re comfortable setting aside for this activity.
Here’s how to manage it:
At Casumo, you’ll find responsible gambling tools that help you keep everything in check, including deposit limits, reality checks, and cool-off periods.
Value betting is all about spotting when the odds are slightly better than the true probability of an outcome.
Let’s say you believe a team has a 50% chance of winning, that’s equivalent to decimal odds of 2.0 or fractional odds of 1/1. If a bookmaker offers higher than that (say 2.5), there may be value there as long as your assessment is accurate.
Value betting involves:
Over time, this approach focuses on long-term consistency rather than short bursts of success.
Sport moves fast. So does betting.
Live sports betting (also known as in-play betting) lets you place bets on matches that are already underway. You don’t need to decide everything before kick-off, you can react to what’s happening as it happens.
At Casumo, our live betting platform is built to help you stay close to the action, with real-time odds, a simple interface, and markets that update by the second.
Live betting means placing a bet while the match or event is in progress. Odds update in real-time based on what’s happening, a red card, a missed penalty, a sudden comeback and you decide when (and if) to jump in.
Here are some common in-play betting options:
Live betting adds a layer of flexibility but it also means decisions need to be quicker, and you’ll want to stay sharp.
Casumo’s mobile site and app are built to keep things smooth, whether you’re on your sofa or on the move.
