Best online casinos
At Casinos Killer we strictly select only the best online casinos available for you to play. While we focus on UK online casinos, we also list online casinos currently not accepting UK players (but that might do it in the future), as long as they are top rated casinos.
We try them, we review them, and we find for you the best promotions available. Each casino review includes information about their customer support, payment methods supported, game providers and their welcome bonus, either with or without a deposit.
Casinos Killer carefully selects the best online casinos for you to enjoy. That’s why the full list of online casinos is not very long: we want you to play only on casinos that we consider excellent! Just browse our list of reviewed casinos where to gamble online, and you will find the best online casinos offering a fun and safe experience, both on desktop and on mobile.
There are thousands of games available including blackjack, roulette, baccarat, online poker, craps and slot machines. Most casinos offer also a live casino option, with live table games and real dealers.
While the table games are the most famous among the public, the online slots are the most played type of casino games, because they are easy to play and can be quite entertaining.
Obviously, every game has different payouts, and so it appeals to different types of players.
In general, the advantages of online casino games are that the majority of the sites offer an opportunity to play a large variety of games for free. The accessibility and availability of the games is also a great incentive to play online. Furthermore, the common practice of offering welcome bonuses, either as a match deposit welcome bonus and as free spins, allows players to try new casinos with no deposit.
Gambling should be fun. We encourage everyone to play responsibly and to seek help in case gambling becomes a problem. Gambling can be addictive.
