Why Low Stakes Stakes?
As we stated above, the RTP is over the long term, calculated over thousands of hands or slot spins. We cannot expect to walk away with virtually the same amount as we deposited each and every time. By playing the lowest stake available on blackjack, it allows us to complete the max amount of hands available and therefore give us a better chance of getting closer to the RTP.
Even at £1 stakes, if we are completing an offer that requires us to deposit and wager £20, we could easily end up £10 down or £10 up as twenty hands is such a small sample size and the RTP can vary massively. However, if you trust in the perfect strategy and the long term EV, even if you end up being £10 down on this offer, it will even itself out over the long term.
Some video blackjack games allow lower that £1 stakes, this is game and site specific, but even polaying at £0.50 stakes instead of £1 allows double the amount of hands.
