Unibet

With more than 15 million customers already signed up to Unibet, they are certainly one of the most popular betting sites around. Indeed, they are the biggest Swedish-owned betting company. And it's easy to see why they've become so successful in recent years when you look at the impressive range of features they offer.

This includes a helpful cash-out option which allows you to take a reduced payout of your overall winnings if some parts of your bet have already won. And this is available across many of the numerous sports they allow you to bet on, including all of the most popular, such as football, rugby and cricket, as well as a few more niche sports like trotting, surfing and even Gaelic sports. They have a number of markets for each one and are known to offer some of the most competitive odds around.

Their online casino has much of the same variety, with a seemingly endless array of classic slots and modern games available. What makes them even more exciting are the tantalisingly high jackpots constantly on offer. These frequently start at £20,000 and go even higher, offering players the chance to net some major winnings.

If you like to play casino games or place bets on the go, then you can do so with their user-friendly mobile website. Having launched their mobile site back in 2004, they've had a long time to hone its looks, and it stands heads and shoulders above many of their competitors' mobile sites currently available. And when it comes to streaming your sports live, then you can do so on both mobile and laptop devices.

This success has hardly gone unnoticed, and Unibet has been the recipient of some highly prized accolades in recent years. These include Sports Betting Operator Of the Year and Poker Innovation Of The Year. UniBet offer one of the best sign up offers with their Money back up to £40 if your first bet loses + £10 Casino offer. T&Cs Apply.
