Blackjack Switch ties losing - House edge?

I've seen a Blackjack Switch game which uses otherwise standard BJ Switch rules (H17, Switched BJ counts as 21, BJ pays even money, Dealer 22 pushes all player's non-busted hands expect Player BJ) but with the exception that also pushing with the dealer loses your bet (every normal push, not 22-push). So for example if you had 17 and 19 and dealer drew to 17, you would lose the first hand and win the second hand.

The RTP is listed as 99.39% for this game, but obviously it cannot be right because of the extra "pushes lose" rule. I checked (from https://wizardofodds.com/games/blackjack/switch/) that the stated RTP value would be correct if pushes didn't lose.

What I want to know precisely, is how much does the "pushes lose"-rule increase house edge from 0.61%? Let's assume that the player plays optimal basic strategy under normal BJ switch rules. Does anyone have BJ Switch computer simulation to come up with a number value?

In regular BJ ties losing adds about 8.5% to house edge, however in this case I believe it's more because initial switching allows you to make more 17-21 hands, which can push, than what you would have in regular blackjack. So I would like to know the exact figure.

Shouldn't your first and foremost concern be when gambling online having confirmed proof you're getting a fair game to begin with? Surely, that overrules any nonsense games that come crawling out of their asses.

I have been notified of this game and have contacted the software provider involved.

It's possible that it's an oversight as the original version did take some ties (before 'Push 22'). Either way, I'm expecting a response in the next day or two so I would avoid speculation until then.

For the record, this is not an approved version of 'Blackjack Switch' and it would never be approved due to the extreme high house edge caused by the additional rule of taking ties.

I intentionally kept quiet on this issue while it was ongoing as it's usually easier to get this type of issue resolved in private conversation rather than on forums. And to that end it is now resolved.

This issue was with GamesOS software, where their blackjack switch was treating all ties as losses for the player while advertising the RTP at 99.39%. GamesOS have now changed the rules back to the standard ties push other than with a dealer 22. You can read the full article on how the various parties handled this issue at(WOO - feel free to pull that link if you feel it's unnecessary).

I personally would be really interested to know the exact effect on RTP that all ties lose makes to the Blackjack Swtich game - I suspect it's going to be far larger than the 8.5ish% in a regular blackjack game?

I'd also like to say 'thank you' to Switch - his involvement really made getting this issue resolved a lot more straight forward.

Dealer taking ties is a rule I see only in two places - church festivals where players essentially can't win...and Double Exposure. The ASM on my shift once yelled at us about exposing the hole card, a practice I'm pretty sure I don't do since most people get crushed at my table, and he pointed out Double Exposure. He told us that the main house advantage is in the dealer taking ties (I read it, and they also limit splits and pay 1-1 on natural BJs too.)

If a casino opened a BJ game with ties going to the dealer and nothing to compensate it, they better come up with either a bunch of stupid people to play it or a hell of a good gimmick, like, say, topless strippers feeding me baked Alaska while sitting in my lap.
