1. Mr Green

Mr Green BonusesThe first on our list is Mr Green Casino. Mr Green has positioned itself as a bastion of trust in a world where it is in scarcity. Its reputation in player privacy, game fairness, and timely payouts are spotless. Considered the true gentleman of online betting, Mr Green provides players with more than 700 games from all top developers.

They offer:

  • online slots
  • live casinos
  • keno
  • bingo
  • sports betting

The mobile gaming section is lit with user-friendly features and a wide selection of HTML5 games. Mr Green’s customer support is also one of the best, providing 12*7 live support in 8 languages across 12 markets. The casino gives a red carpet welcome to new players with a 100% cashback up to £100 on the first deposit.

Mr Green is one of the oldest casino operators, and it has its share of responsibilities. Its Green Gaming Policy is a great step toward Responsible Gambling, where the casino employs AI technology to detect risky betting behaviour and nudge players against taking wild risks. It also empowers its players with various tools for self-assessment and loss management, which is excellent for the industry’s healthy growth.

It’s no wonder that it won the EGR Nordics Awards 2021 – Safer Gambling Operator of the Year and the EGR Marketing and Innovation Award 2019 – Innovation in compliance and responsible gambling.

2. NetBet

NetBet is a popular allrounder-the jack of all trades and master of some. It commands a loyal player base through its exclusive High Rollers Club and frequent promos. The poker rooms of NetBet are widely popular and have some of the best bonuses in town.

NetBet Welcome Bonuses:

  • New poker punters can double up their first deposit at the casino up to £1500
  • Casino games and sports bettors can claim a 100% cashback up to £200.

The slots games are mostly from NetEnt, but few other reputed developers can also be found. The live casino section is particularly known for its blackjack tables, powered by Evolution Gaming, Ezugi, and Pragmatic Play.

3. Casumo

Casumo is a new-age betting platform known for its unique innovations.

It has always been:

  1. responsive to the needs of the gambling community,
  2. introducing gamified bonuses,
  3. having personalised VIP schemes,
  4. offering instant banking, and
  5. having a portfolio of more than 2000 games.

A rich ecosystem of tournaments makes Casumo the proving ground for the betting community.

Being a technology-driven company, the design team of Casumo has reshaped the way we bet. Its web design feels modern and is particularly attractive to new-age gamers.

The award-winning Casumo mobile app is extremely intuitive and fast, taking its sports betting app far ahead of the competition in terms of design and betting depth.  Casumo currently offers a 100% bonus up to £25 and 20 Bonus Spins on the Book of Dead Slot for all new UK players.

4. Betfred

If the old is gold, Betfred is the true king of the UK gambling scene.

  • Established as a betting shop in Manchester in 1967, the brand quickly scaled new heights to become a household name in the United Kingdom.
  • In 2005, it digitised its operations to become one of the first online casinos in the UK.

The casino’s reputation precedes its brand, and high rollers naturally gravitate towards Betfred for its security guarantee. It is a Playtech exclusive casino where you can find more than 100 slots and a range of live casino tables.  The Betfred app is a great way for punting on the go and is available on Android and iOS.

Betfred offers a modest welcome deposit bonus of 50 free spins on the Age of Gods slot for your first deposit at the casino. It’s a great way to explore the classic casino with just a £10 minimum deposit and no-wagering requirements.
