The Lightning Fee and Net RTP
Every round requires a mandatory fee equal to your main bet. If you wager ten dollars, the game takes another ten dollars as a fee. This fee funds the multipliers. It does not get returned if you win or push. This structure means you are risking double your standard bet on every hand. Because of this fee, the short term volatility is much higher than standard blackjack. The theoretical RTP of 99.56% only applies if you play perfectly and stay long enough to use your earned multipliers. Leaving early leaves money on the table.
