About 21 Duel Blackjack

21 Duel Blackjack by Playtech is a slot playable with cryptocurrency on Stake. Its stated RTP is 98.38% — above the 96% industry average, which is favourable for players over the long run. Remember that RTP is a statistical average over thousands of spins, not a guarantee for any single session.

The maximum potential is 20× your stake. This is the payout ceiling, reached very rarely and usually only via the top bonus feature; treat it as a limit, not an expectation.
