Hello Forum!

Recently I've heard a lot about the game Double Down Madness but I could not find a demo online.

I decided to make my own this morning which you can play on my Table Games Academy website at this link. I hope you enjoy it and let me know if you have any issues :) There are a couple alternate pay tables that I might add later which involve suited blackjacks.

I’ve tried it. Add up the hand value after each hit and then display the number on screen. That will save player a lot of brain calculation.

Temporarily coming out of my self-imposed exile in order to bring up some new developments regarding this game. Hope everyone had a nice Valentine's Day full of love.

1) I had to take down this game from my website but you can play the AGS variant Double Up Insanity on my website now.

2) A dealer recently sent me a new type of Push 22 bet with the following pay table and asked me to analyze it:
Suited 21 - 50:1
Colored 21 - 20:1
Other 21 - 8:1
Through simulation, I calculate the RTP to be around 94.1% (given six decks and hitting on Soft 17), which is better than the original 11:1 Push 22. I have an idea of how to solve this "iteratively" but I don't think it would be worth my time right now...

3) I saw a Double Down Madness strategy that was posted online that differs slightly from the Wizard strategy. Maybe the original DDM strategy had some minor mathematical errors? Anyways I thought I should share it with y'all:

Your Double Up Insanity demo game freezes when player gets an Ace, doubles and then gets a ten-valued card. The dealer cards are then exposed but player is not offered a chance to wager on a new hand.

Thanks for catching that - there was an issue with unsuited blackjacks which should be fixed now :)

Another apparent issue:

I had an 8 vs J. I hit the 8 and received a second 8. I was not allowed to split the 8,8 pair.

Okay, but when I clicked on Rules, it included this sentence: "If you start with two cards of the same value you can split them into two new hands."
Later it listed

Double After Split: Allowed

and

Maximum number of splits: 3

Indeed, the Rules statement appears to be for generic Blackjack, because it never mentions any of the unique rules of Double Up Insanity.

Respectfully, you have so many BJ variants that it's hard to keep them straight unless you do a better job of telling us what the ding dong rules are!

The problem with any side-bet, such as the 21 one, is the player could use a small Blackjack bet so will split and hit just to try and get to 21. I'm guessing, even if they needed to beat the dealer and got a push 22, paying 8 for 1 is in the Player's advantage.
I'd guess the designer could insist the BJ bet was equal or larger, and then one needs to analyse the strategy when they are equal. As you say this probably needs a type of recursive combinational analysis looking at all the possible player hands.

Sorry it was a typo, the Push 22 bet is regarding the dealer’s suited, colored, or regular 22. You can try it on my website now
