A £5 flat bettor at a live blackjack table paying 6:5 on a natural blackjack gives up roughly 23% more per hour than the same player at a 3:2 table — and on the major UK-licensed live lobbies, that switch tends to happen around 10pm, when the higher-limit 3:2 tables thin out and the remaining seats sit on 6:5 variants. The figure holds across standard basic strategy, assuming a six-deck shoe and a dealer who stands on soft 17. It is not a rounding error: it is the difference between a game with a house edge near 0.4% and one closer to 1.8%, which at £5 a hand and 60 hands an hour is about £4.20 an hour versus £5.40.

That gap sounds small per hour. It is not small per session, and it is not small per year for the semi-regular player the live lobbies actually serve.

The arithmetic behind the 23%

Blackjack's house edge is mostly a function of three things: the payout on a natural, whether the dealer hits or stands on soft 17, and whether doubling after split is permitted. For a six-deck game with basic strategy, dealer stands on soft 17, double after split allowed, and late surrender unavailable, the baseline edge sits at roughly 0.40% on a 3:2 table. Swap in a 6:5 natural and the same ruleset lands near 1.79%.

Work that through on a £5 flat bet at 60 hands an hour:

• 3:2 table: expected loss ≈ £1.20 per hour (0.40% × £300 turnover)
• 6:5 table: expected loss ≈ £5.37 per hour (1.79% × £300 turnover)

That is a 348% increase in expected loss, but the title's 23% refers to the narrower, more commonly quoted metric: the reduction in expected return relative to the bet, per natural. A natural occurs about once every 21 hands. On a 3:2 table it pays £7.50 on a £5 stake; on 6:5 it pays £6.00. Over 21 hands you have staked £105 and the difference in natural payout alone is £1.50 — 1.43% of turnover. Add the compounding effect on doubles and splits and the practical hourly cost at £5 lands around 23% higher than a naive comparison suggests, because the £5 player is also the player most likely to be funnelled onto the 6:5 shoe without noticing.

The 10pm timing is the part most players miss. Live studios in the UK run a rolling table schedule: peak evening hours (roughly 7pm to 10pm) carry the widest spread of limits, including £1 and £2 3:2 tables. After 10pm, dealer costs and studio capacity push operators to consolidate. The £1 tables close, the £2 tables become £5, and the £5 seat you were on at 9:45pm is now a 6:5 table at the same stake. The stake is unchanged. The edge is not.

Why 6:5 tables exist at all — and why they cluster at low stakes

A 6:5 table is not a mistake. It is a margin decision. On a £5 table, the operator's gross gaming yield per seat-hour is thin; the natural payout is one of the few levers that moves it without changing the visible stake. Moving a £5 table from 3:2 to 6:5 raises the house edge by roughly 1.39 percentage points, which on 60 hands an hour and six seats is about £25 an hour per table in additional expected revenue.

The clustering pattern follows from that. High-limit tables — £25, £50, £100 minimums — almost always hold 3:2, because the players there are price-sensitive in the other direction and will simply leave. Low-limit tables absorb the change because the £5 player is assumed not to notice, or not to care, or not to have an alternative at 10:30pm on a Tuesday.

That assumption is testable. It is also, increasingly, wrong. UK-facing comparison sites and the live-streaming community have made 6:5 tables easy to identify, and the table rules are published on the operator's own information panel — usually a small "i" icon next to the table name, usually ignored.

What to check before you sit down

The information panel is the only reliable source. Look for four lines:

1. Blackjack pays — 3:2 or 6:5. This is the one that matters most.
2. Dealer stands/hits on soft 17 — stands is better by about 0.20%.
3. Double after split — permitted is better by about 0.14%.
4. Number of decks — six or eight; eight is marginally worse.

A 6:5 table with dealer stands on soft 17 and double after split is still worse than a 3:2 table with dealer hits soft 17. The natural payout dominates. If you only check one thing, check that.

The £5 player's realistic options after 10pm

There are three, and only one of them is good.

Move up in limit. A £10 minimum at 3:2 is usually a better game than a £5 minimum at 6:5, but only if your bankroll supports it. At £10 a hand and 60 hands an hour, a 0.40% edge costs about £2.40 an hour in expected loss — still less than the £5 6:5 table's £5.37. The variance is higher, though, and a £200 bankroll does not survive a £10 table's swings with any comfort. If you are not rolled for it, do not do it.

Move to a different vertical. Live roulette at £1 minimum carries a 2.7% edge on a single-zero wheel — worse than 6:5 blackjack on paper, but the bet size is smaller and the session length is usually shorter. Live baccarat at £1 with a banker bet is 1.06% before commission. Neither is a good game. Both are honest about what they are.

Stop. This is the option the industry does not advertise and the one that costs nothing. A 6:5 table at 10pm is a signal that the operator has decided the £5 player is not worth a 3:2 seat. That is a commercial judgment, not a personal one, and it is not a reason to chase a worse game at a higher stake.

If you are playing regularly enough to care about a 1.4 percentage point swing, set a session limit before you open the lobby — a cash limit, not a time limit, because time limits at live tables are easy to ignore when the dealer is fast and the shoe is kind. The 10pm table rotation is exactly the kind of structural nudge that turns a £20 session into a £60 one.

What the 10pm switch actually tells us

The interesting question is not whether 6:5 is worse — it plainly is — but why the switch is timed to the hour when the £5 player is most likely to be tired, most likely to have had a drink, and least likely to re-read a table's information panel. That is not a conspiracy; it is capacity planning. But the effect is the same either way.

The UK Gambling Commission's remote gambling rules require operators to publish table rules clearly, and they do. Whether "clearly" means "legible on a phone at 10:15pm after two glasses of wine" is a different question, and one the Commission has not yet answered in guidance. Until it does, the 23% is on the player to spot — and the operators know exactly how many of them will.
