Hello!

Been playing this pretty fun variant, couldnít find a write up anywhere. Might not be able to get the exact house edge because there is a bonus wheel with percentages I havenít been able to find.

You make 5 equal bets: 4 standard hands of blackjack and the mandatory 20s bet. The required side bet pays based on the number of 20s (hard or soft) that get dealt. The bet pays once cards are dealt. Hitting to 20 does not count, and outcome of the hands themselves donít matter

1: spin a wheel of push , 1x 2x or 3x your bet
2: 4 to 1
3: 20 to 1
4: 420 to 1

One thing I like is even though itís $25 per hand (a lot for me, especially when itís just on a couch at home) you only need to win 3/5 spots to come out ahead and you donít lose all 5 spots too often

I think you can play this game for free if you live in a state where online gaming is legal and you can download the draft kings app. Once youíre signed in, there is an info button on the logo and you can select demo.

Iíve mostly been playing basic strat, but was wondering if the mandatory side bet opens for some ďfreeĒ doubles or splits you wouldnít normally go with

Has anyone played this? I think itís really a fun take on BJ

Initial review: S17, split to four hands, no resplit aces, split aces one card only, double any initial hand.

8 Decks, shuffled every round.

The wager on each hand and the four 20s sidebet must be identical. If you bet $5, $1 goes on each spot.

I didn't see anything egregious in their suggested strategy (under settings/paytable on the demo), but I didn't do a close review.

I didn't play enough rounds to get a good feel for the sidebet spinner weighting. Based on the graphics, my guess is that the spinner offers 6 fair stops, of push - 1x - push - 2x - push - 3x.
May the cards fall in your favor.

At least in the web demo version, the $5 table minimum is satisfied by a $1 bet on each spot, for $5 total per round.

To get dealt 4 20's, the chance is about 1/7.8k, for infinite*** decks (if I worked it out right).

***: The game is played with 8 decks (going by posts above)
Note : I have played it in demo mode before, but I don't know the value for getting 1 20

At the infinite deck level, I get a player edge of 2.43% for the bonus game (see figures below)

Chance / Odds / EV:
0 x 20 = 63.7325023584590000% / blank / - 63.73%
1 x 20 = 30.3890077470798000% / 1 to 1^^^ / +30.39%
2 x 20 = 5.4337960872262000% / 4 to 1 / +21.74%
3 x 20 = 0.4318248546140020% / 20 to 1 / +8.64%
4 x 20 = 0.0128689526209471% / 420 to 1 / +5.40%

Total EV = -63.73% + 30.39% + 21.74% + 8.64% + 5.4% = 2.43%

^^^: Assuming that the "spinner offers 6 fair stops, of push - 1x - push - 2x - push - 3x.". as stated in the "snipped quote", above.
Note: Again this is for infinite decks,

I estimate about 1 in 14500. This is not exact, it's an estimation.

edit: I am notoriously bad at math.

I originally got that, but then I remembered that A-9 and 9-A, also count as a 20 for the "bonus".

Note: I played it about a week or two ago, so they may have changed the rules?

Well, I only played about 5 deals, and forgot entirely about soft 20.

I think that the odds are likely to favor the house. ;)

Probably, but I get a small player edge at infinite decks, if all pays are " to 1" for the bonus.
Note: I may be able to work out a more accurate chance and EV, but I am slower at doing it the "correct way for 8 decks" (compared to the infinite deck "short-cut estimate")

For 8 decks, I get about 0.0114...% as the chance*** for "4 x 20".

***: I took some more short-cuts in getting this "8-deck" figure, because I didn't want to manually work out all the "16 ways you can get 4 x 20".

Important Update (about 10:45 pm, Pac time):

Reminder, the "2.43% player edge" that I mentioned in previous replies, was for infinite deck only, the "8- deck edge" will almost surely be in the houses favor.
