# RTP in blackjack and the strategy it assumes

> What a published RTP for a blackjack table assumes about how you play, how it differs from slots, what RTS 3 requires, and how not to confuse it with your session.

RTP, return to player, is the share of stakes a game is expected to pay back over a very large number of rounds. At a blackjack table it rests on assumptions about how decisions are made, which the studio should state. As of 13 November 2026 we have not recorded any table's figure; this page shows how to read one.

## What the figure assumes

A slot's outcome does not depend on your choices. Blackjack's does: you decide whether to hit, stand, split or double down.

So a published RTP needs a stated assumption about those decisions. One possible assumption is a fixed strategy for the table's rules, described in [basic strategy](https://seatcheck.uk/basic-strategy/). Check the studio's wording and its date, and note whether the figure names the strategy at all. If it does not, treat the number as unexplained until the studio says how it was calculated.

**Seat note:** an RTP for a skill-influenced game is only as meaningful as its stated assumptions.

## The requirement to make it available

The Gambling Commission's Remote Technical Standards include RTS 3, on rules, game descriptions and the likelihood of winning. Our country reference points to RTS 3C for RTP being available to the player.

We cite the rule; we have not tested any operator against it. Source and date are on [where our figures come from](https://seatcheck.uk/data-sources-and-dates/).

## From RTP to house edge

House edge is 100% minus RTP. A figure of 99.00% means 1.00% and an expected loss of £1.00 per £100 staked. Both numbers here are for the sum, not published values.

**RTP to expected loss per £100 staked · derived by us for illustration**

| Assumed RTP | House edge | Expected loss per £100 |
|---|---|---|
| 99.50% | 0.50% | £0.50 |
| 99.00% | 1.00% | £1.00 |
| 98.00% | 2.00% | £2.00 |

See [house edge](https://seatcheck.uk/house-edge/) for the definition.

## Do not read it as your session

An RTP of 99.00% does not mean you will get back £99.00 of every £100. A single session can end well above or below. The sum uses a very large number of hands.

## FAQ

**What does RTP stand for?**

Return to player: the share of stakes a game is expected to pay back over a very large number of rounds.

**Does a blackjack RTP assume I play well?**

A blackjack figure rests on stated assumptions about decisions. We could not confirm the wording for any table yet, so read the studio's own note.

**Do operators have to make RTP available?**

The Gambling Commission's RTS 3 sets requirements on game information and the likelihood of winning, including RTP. We cite it as the rule; we have not tested any operator against it.

**Is RTP my expected result tonight?**

No. It is a long-run average and says little about one session.
