What is the RTP of Single Deck Blackjack Professional Series?

The RTP is 99.59%, giving a house edge of 0.41% when playing correct basic strategy. A Low Limit and High Limit variant carry identical rules and the same RTP figure with different bet ranges.

Who developed Single Deck Blackjack Professional Series?

The game is developed by NetEnt as part of their Professional Series table game range. The Low Limit version was released in April 2016.

What are the doubling down rules?

You can only double down on a hard 10 or hard 11. Doubling on any other hand total is not permitted, and doubling after a split is not allowed. You receive exactly one card after doubling.

Can you split hands in Single Deck Blackjack Professional Series?

Yes. You can split any pair of equal-value cards, but only once per round - re-splitting is not available. After splitting Aces, you receive one card to each hand and must stand immediately.

Is card counting possible in this game?

No. The single 52-card deck is reshuffled after every hand, so there is zero penetration. Each hand begins from a fresh deck, making card counting mathematically ineffective. The single-deck RTP advantage comes purely from the rule structure, not from any ability to track cards.

Single Deck Blackjack Professional Series - 99.59% RTP

Q: Does the dealer hit or stand on soft 17?

The dealer hits on soft 17. That rule costs the player approximately 0.2 percentage points compared to a stand-on-soft-17 game, and it is factored into the published 99.59% RTP.

RTP	99.59% - Compare RTPs

Single Deck Blackjack Professional Series is a NetEnt table game built around a single 52-card deck, reshuffled after every hand. That design choice delivers an RTP of 99.59% - a house edge of 0.41% when playing correct basic strategy. Six-deck online blackjack typically runs at 0.5-0.6% house edge. The difference is small in absolute terms, but across hundreds of hands it matters to players who care about value.

Rules

One standard 52-card deck, reshuffled after every hand. Blackjack pays 3:2 - not the 6:5 payout that has crept into many online variants and adds roughly 1.4% to the house edge. The dealer hits on soft 17, which costs the player approximately 0.2 percentage points compared to a stand-on-soft-17 game. That cost is already included in the published 99.59% figure.

Doubling down is restricted to hard 10 and hard 11 only. You cannot double on any other total, and doubling after a split is not permitted. Splitting is available on any equal-value pair, once per round only - re-splitting is not available. After splitting Aces, you receive one card to each hand and must stand. No surrender option exists. Insurance is offered when the dealer shows an Ace.

Bet limits on the standard version run from £0.10 to £40. A Low Limit variant (released April 2016) and a High Limit variant carry identical rules with adjusted stake ranges.

House Edge and Basic Strategy

The 0.41% house edge only applies when you play every hand correctly. Casual decisions - standing when you should hit, skipping a double when the maths supports it - shift the effective house edge upward quickly. On a single deck, the removal effect of each dealt card is stronger than in a six-deck shoe, which means single-deck strategy charts differ from multi-deck ones in specific spots.

Key single-deck adjustments worth knowing: double hard 11 against a dealer Ace (multi-deck basic strategy says hit in this spot); double hard 9 against dealer 2-6 more aggressively than the multi-deck chart suggests; double soft 18 (Ace-7) against dealer 3-6 rather than standing. These are standard single-deck deviations backed by the mathematics of reduced deck depth.

The doubling restriction to 10 and 11 only costs several tenths of a percent compared to unrestricted doubling rules. The dealer hitting soft 17 costs around 0.2%. These rule trade-offs explain why the house edge is 0.41% rather than the sub-0.2% figure you see quoted for single-deck games with more liberal rules.

Card Counting and Deck Penetration

Single-deck games are historically the target of card counters because fewer cards mean each dealt card has a larger effect on the remaining composition. A true count swing of +2 in a single-deck game carries more weight than the same count in a six-deck shoe.

This game eliminates that advantage entirely. The deck reshuffles after every hand, so penetration is zero - you always start against a fresh 52-card deck. Card counting is not possible. Each hand is mathematically independent, and the probability distributions reset fully before every deal. The single-deck RTP advantage is real, but it comes without any additional skill edge from tracking cards.

Insurance

When the dealer shows an Ace, NetEnt offers insurance at 2:1. On a single deck, after one Ace is visible, there are 51 cards remaining. Sixteen of those are ten-values (10, J, Q, K). That gives a dealer blackjack probability of 16/51, approximately 31.4%. For insurance to break even at 2:1, you would need a 33.3% probability. The gap is about 2 percentage points, giving insurance a house edge of roughly 5.9%. Decline it every time.

Interface and Play Speed

The Professional Series interface keeps visual noise to a minimum. Chip denominations of £1, £5, and £25 sit at the bottom. Deal, hit, stand, double, and split buttons appear contextually - double and split only show when the current hand qualifies for those actions, which removes guesswork. A rebet button repeats the previous stake for faster session pacing.

Because the reshuffle happens after every hand, there are no shoe-management pauses. The game runs at a consistent pace regardless of how many hands have been played. HTML5 delivery means the same codebase runs on desktop and mobile without a separate app download. Touch targets on mobile are sized adequately for accurate play.

Comparing Other Blackjack Games on the Site

If you want multi-hand action, Multi Hand Premier Blackjack Gold lets you play up to five hands simultaneously from a shoe. Premier Blackjack Hi Lo Gold adds a side bet on whether the next card will be high or low - the main game rules are similar but the side bet carries its own house edge. Spanish 21 Blackjack Gold removes the four 10s from the deck, giving players additional bonuses to compensate but altering basic strategy significantly.

For Vegas rules, Vegas Strip Blackjack uses four decks with dealer standing on all 17s and more liberal doubling, while Vegas Strip Blackjack Gold is the Microgaming version of the same ruleset with a polished interface. Single Deck Professional Series suits players focused on minimising house edge with correct strategy.
