What You’re Walking Into
Locals still tend to call it The Casino at Mint, but the sign over the door now says Genting Casino Cromwell Mint. Same building, same South Kensington spot, just new branding on the front. So if you have been typing “old Mint Casino London” into maps, this is the place you are really looking for.
You will find it at 43-45 Cromwell Road, SW7 2EF. It sits between Gloucester Road and South Kensington Underground, close enough that even if you pick the “wrong” station it is only a short stroll. The Natural History Museum is right round the corner, which makes the casino very easy to pin down on your first trip.
For table players, blackjack is usually the main event. On most nights the floor spreads five or six blackjack tables, depending on how busy it is and how the room is set up. Around them you will see American roulette, baccarat, three card poker, and a chunk of space given over to electronic machines. This is a full casino floor environment, not a tucked away side room with a token table or two.
Entry itself is free. You do not need to arrange membership in advance. You walk in, show ID if someone at the door asks for it, and that is you inside.
Stakes and Table Limits
Before you pull a chair out, it helps to know roughly what each hand might cost. At Cromwell Mint, blackjack usually starts in the £2 to £3 per hand area, which is very low by central London standards, and rises all the way up to around £3,000 per hand on the top tables. That single range comfortably covers the casual player sitting in for a few small hands and the regular who wants a much bigger session.
Other games sit on their own spread of limits. The floor typically looks something like this:
| Game | Minimum Stake | Maximum Stake |
|---|---|---|
| Blackjack | £2-£3 | £3,000 |
| American Roulette | £0.50 | £200 |
| Baccarat / Punto Banco | £5 | £5,000 |
| Three Card Poker | £5 | £200 |
The Mint card room inside the same building, which is focused around poker and extra tables, can run different limits to the main floor. The numbers can shift with time and demand as well. So always glance at the minimums printed on the layout before you sit down, more so when you move from one area or game to another.
How to Actually Get to a Table
If you have never played blackjack in a land-based UK casino, the flow from the pavement to your first hand can feel a bit formal at first. Once you have done it once, it is all very straightforward.
- First get yourself to 43-45 Cromwell Road. Think smart casual clothing. Football shirts, heavy workwear or anything that looks like you just came straight from a building site can be turned away at the door.
- At the entrance, you may be asked to show photo ID. A passport or photocard UK driving licence both work without fuss. UK law says the casino must make sure you are at least 18, so take something valid even if you look older and assume nobody will check.
- Go to the cashier desk before you sit at a table. Hand over cash there to receive chips. You cannot just throw notes into the betting circle - buy-ins run through the cashier rather than straight to the dealer.
- Walk the floor and pick out a blackjack table with a free seat that matches the stakes you want. If it looks busy or you are not sure where blackjack is running, ask a member of floor staff and they will direct you.
- Stand behind the chair until the current hand finishes, then sit in. When the dealer signals the betting time, place your chips in the betting circle in front of you.
- The dealer will deal two cards face up to each player. The dealer then takes one card face up and one card face down for themselves.
- Now you act on your hand. Hit means you ask the dealer for another card. Stand means you are done and happy with your total. If you double down, you double your original wager and agree to take exactly one more card, then you must stand. If your first two cards are the same value, you may split them into two separate hands and place an extra bet for the new hand.
- When your opening two cards make 21 - an ace with any ten-value card - that is a blackjack. On these tables it pays 3:2, which is the solid, standard payout you want. If at any point your total passes 21, your hand is bust and you lose that stake there and then.
Once you decide you are finished for the night, take your remaining chips back to the cashier. Dealers on the blackjack tables do not push cash to you directly for colour-ups.
A quick piece of general advice, not specific to this room: if blackjack is new to you, it is worth ten quiet minutes with a basic strategy chart before you ever sit down. It will not magically make you win, but it will help you avoid decisions that are just mathematically bad for you.
The Rules Applied Here
Blackjack at Cromwell Mint follows the usual UK-style structure. Even so, a handful of rules are worth having clear in your head before you risk the first chip.
The dealer stands on soft 17. In practice this means if the dealer is holding an ace and a six, they do not draw again. They simply stay where they are. From a player point of view that rule is better than the version where the dealer has to hit soft 17.
A winning blackjack hand pays 3:2, not 6:5. That small looking difference has a big effect over time. 6:5 payouts quietly push more money towards the house edge, so seeing 3:2 on the felt is exactly what you want before you even think about buying in.
If the dealer goes bust, every player who still has a live hand wins their bets. The slightly harsh part comes earlier. If you bust your hand first, your chips are gone regardless of what the dealer does later. Even if the dealer then busts as well, your earlier loss does not reverse. The moment your cards go over 21, that wager is settled and finished.
Splitting is an option whenever your first two cards share the same value. Most of the time, aces can only be split once, and each of the new hands will take one extra card. Doubling down is usually allowed on any two-card total in a UK venue like this, but there are sometimes small variations between tables. Just ask the dealer to confirm what is allowed at the place you are sitting before you really start ramping up your stake.
