House edge contribution of End-16 rule?

Recently there have been several new BJ variants (by Score Gaming LLC) which feature the End-16 rule.

This rule is similar to the more popular Push-22 rule in that it’s intended to compensate for other rules that favor the player. But instead of having remaining live bets push on 22, the End-16 rule says that the game ends and all remaining live bets will push if the dealer gets to a soft or hard-16, except player 21s which will pay even money instead.

One increasingly popular variant is Double-up Blackjack which the Wizard has already analyzed. This variant allows the player to double their bet on any 2 card 20 or below and stand. It appears to be a very good game with just a 0.32% house edge.

What I’m interested to find out is, which among the push-22 and end-16 rules increase the house edge more? And if the push-22 rule contributes +6.9% to the house edge (correct me if I’m wrong), how much does the end-16 rule add to the edge?

Other new End-16 variants by Score Gaming which I’ve come across are Flip-It blackjack (if the dealer upcard is an ace or 10-value card, downcard is exposed) and Super Split blackjack (player allowed to split any 2-card hand of the same color, once per box).

I see this is an old post but I have an answer. I followed the Wizard's YouTube video on creating basic strategy from scratch in Excel and then finding the house edge for infinite decks. I did a traditional H17 game and a H17 game with the End 16 rule. The house edge for the traditional H17 game with infinite decks was 0.6883%, and the one for the game with End 16 rule was 5.3879%. That's about a +4.7% swing, which is less than the Push 22 rule.

This part is confusing: “I did a traditional H17 game and a H17 game with the End 16 rule.” Do you mean H16 or hit soft 16?
Anyway, this is cool. Is it a lot of work to do these modifications?

They meant that two separate rulesets were simulated:
Ruleset 1- BJ with traditional H17 rules.
Ruleset 2- BJ with traditional H17 rules but all live player bets push when the dealer reaches soft or hard 16 at any point, except for player 21 which pays even money instead.

@grossmyn: Appreciate the response. Interesting results. Personally end-16 is more fun than push-22 because—
1. Getting to 21 actually results in a win more often than in traditional blackjack due to the dealer stopping at 16 but still paying even money.
2. The dealer stopping at 16 rather than drawing another card can actually save your ass sometimes if that next card would have been an A2345. And take the case of the player having a 12-16 with the dealer showing 5 — if the dealer flips an ace underneath making soft 16 I believe taking a push at this point is higher EV for the player than the dealer continuing to draw.
3. With push-22 a supposedly guaranteed win if the dealer busts with 22 instead results in a push. This is especially painful when you’d already drawn to 21.

Oh, I see. That means your naming of this game is not accurate. I would call this game Early Push Blackjack.

But, I’m worried this game may become another Pai Gow poker because it pushes too many times.
