With a minimum bet of just 10p per hand, SG Digital’s Super Fun 21 is an online blackjack variant that is very accessible.
It’s an RNG game with a side bet based on being dealt blackjack in a specific way, but there are a few tweaks to the base game too.
The player can bet on up to three hands at the same time if they wish, but the maximum ante win per hand is £640.
Gameplay and Rules
The game is played with six decks that are shuffled between each hand, and if you discount the Diamond Bonus then gameplay isn’t very different from a standard game of blackjack.
However, there are a few rule changes to be aware of:
- Blackjack pays 5:2
- A five/six card 21 is an automatic win at 2:1 (no doubling)
- A six card 20 is an automatic win at 2:1 (no doubling)
- Player can double up to three times
- Can only split pairs once
- House hits on soft 17, stands on hard 17
- Dealer checks for blackjack
There is also the option to surrender your hand at any time after the initial deal once the dealer has checked for blackjack.
Choosing this option will return half of your stake and forfeit the other half to the house.
Lastly, drawing 6 cards without going bust will win you the hand regardless of the total value of your hand. This pays out at 1:1.
Diamond Bonus Side Bet
With this side bet, you are wagering that you will not only be dealt blackjack, but that both of the cards in your hand will be diamond suited.
The odds for this are low, but the payout is high at 250:1.
To use the bet you just have to lay an extra stake on the area highlighted in yellow above. You can choose any amount and it does not have to be the same as your stake on the base game, however, you cannot play the side bet without also playing the base game.
This bet is optional so you can totally ignore it if you want to, but if you happen to land a blackjack made up of two diamond suited cards and don’t have money down on this bet you will not receive the extra payout.
There are a few different theoretical return to player percentages to consider here.
The base game comes in at 98.71% when playing optimal strategy, which isn’t great as a good player can push that above 99% in a standard game.
But then a standard game doesn’t give you the option to win 250:1 with a side bet, although the RTP for the Diamond Bonus is just 74.50%.
Lastly, if you take insurance (which is generally not a good idea) you will be betting with an RTP of 92.60%.
