It's generally not advisable to play blackjack with a 6:5 payout on Blackjacks. This payout significantly reduces your potential return compared to the standard 3:2 payout. With a 6:5 payout, you only receive $6 for every $5 bet on a blackjack, whereas the traditional 3:2 payout gives you $7.50 for the same bet. This decrease in payout lowers your overall winnings and increases the house edge, typically by about 1.4%. The result is that the odds of winning are reduced, making the game less favorable in the long run. While 6:5 games may be more accessible or lower in cost, it's better to avoid them if you have the choice. When comparing, a 3:2 game is the smarter option for maximizing your chances and returns.
