RTP in blackjack and the strategy it assumes
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. 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.
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.
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.
| 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 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.
Whether playing to a chart changes the result is checked in does basic strategy cut the house edge. To try your own numbers, use the house edge calculator.
Quick answers
