21 Casino review

21 Casino is an online casino that’s run by Imperium Network Solutions Limited Casinos. INS also run a handful of other online casinos, including Huge Slots Casino, Jackpot Luck Casino and 21 Prive Casino. They are licensed and regulated by the UK Gambling Commission.

The number ’21’ is one commonly found in casino lingo, and there are a number of sites that have created their name with ’21’ in mind, inclduing 21 Dukes, 21 Bets and the afore-mentioned 21 Prive. Just in case you’re brand spanking new to the world of gambling, 21 is the maximum total either you or the dealer can score while playing blackjack. If you hit and the total pip count of your cards tumbles over the 21 barrier, then you’ve bust, and lost.

So, is 21 Casino a bust or a blackjack? You’d just better keep on reading to find out …

Promotions and bonuses

Things start off brightly at 21 Casino with – of course – 21 free spins on NetEnt’s brilliant Starburst. These free spins come unburdened with the need for you to make a deposit – you simply have to registered and those bonus spins are yours. It’s not all good news though – any winnings you receive from your free spins are capped at £50 and are paid as bonus money.

There are also three deposit bonuses you can claim while a newbie at 21 Casino, on your first three deposits:

  • First deposit – 121 percent bonus up to £350 + ten free spins
  • Second deposit – 30 percent bonus up to £100 + ten free spins
  • Third deposit – 60 percent bonus up to £100 + ten free spins


Your wagering requirements for your deposit bonuses or your free spins winnings are 35x. You can only use slots, ‘fun’ games, scratch cards and ‘ball’ to meet your requirements. The minimum you need to pay per bet for a slot machine spin or scratch card ‘scratch’ is £0.25. You cannot use table games (including live games), poker games or the following slots: Blood Suckers, Dead or Alive, Devils Delight, Kings of Chicago, Beetle Frenzy, Gold Rush, Jackpot 6000, Lucky 8 Line, Magic Love, Mega Joker, Pirate’s Gold, Safari Madness & Super Nudge 6000 or Big Bad Wolf.

For all your deposit bonuses the minimum amount of cash you need to deposit to qualify is £20. You can also earn £25 for each friend you refer to 21 Casino, as long as they make a deposit of £20.

21 Casino says that it likes to reward loyal players by treating them like royalty. We’re not sure about that, but the site does run a five-tier loyalty rewards scheme, from Bronze to Platinum. You are automatically enrolled into the scheme when you join at the Bronze level, and you can ascend to Platinum if you can acquire an average of 15,000 points per month.

You earn points for every £10 you spend at the casino. Most games will earn you one point per tenner, but some (such as slots and scratchcards) earn you two, and others (like blackjack) only a half. You can redeem every 1,000 loyalty points you earn for a fiver. In addition, the further up the scheme you rise, the better offers and bonuses you receive.



It’s mainly slots at 21 Casino, and the big news is that most of them are provided by whom many regard as the best providers in the business – NetEnt. You’ll be able to enjoy classics such as Gonzo’s Quest, Jack Hammer 2 – Fishy Business and Spiñata Grande here. Able slotting backup is provided by NextGen Gaming and 1X2Gaming, among others.

Moving onto the tables you’re sure to be thrilled by the variety on offer here. How does seventeen versions of blackjack sound? Or a dozen versions of roulette? There are also four versions of arcade bingo, eleven scratchcards and nine versions of virtual sports betting games.

The only downers perhaps are there being just four video poker games and two versions of baccarat. There’s also an absence of craps, sic bo or pai gow poker.

Fans of live casino games can enjoy roulette or blackjack.

Casino snapshots

21 Casino looks pretty appealing, we have to say. It’s a fairly standard design that’s been transformed a little bit, and is not as cluttered as some casinos we have seen. The menus are easy to navigate and finding your way to your chosen pastime is nice and easy. Our only quibble is the large size of the thumbnails which means finding your favorite slots game sometimes can take a lot of scrolling.



Software is provided by NetEnt, NextGen Gaming, Microgaming, 1X2Gaming and Thunderkick. Non-UK players can also enjoy Betsoft slots, which are restricted in the UK due to licencing issues.

The site will work just as effectively on your Android or Apple smart phone.

Live support is offered 24/7. We gave it a try, but we can’t admit to being impressed.

Available Software: 1X2gaming, Microgaming, NetEnt, NextGen Gaming.
