Blackjack 21+3 Demo Review
Blackjack 21+3 is a single-hand blackjack game by iSoftBet on a deep purple table, with an optional 21+3 side bet next to the main betting circle. The demo starts with $1,000 in virtual credits and chips from $0.1 to $10. The main bet runs from $0.1 to $100 and the side bet from $0.1 to $50.
Table Rules on the Felt
The felt states that blackjack pays 3 to 2, the dealer must draw to 16 and stand on all 17s, and insurance pays 2 to 1. A regular win pays 1 to 1, and the game offers Hit, Stand and Double. The number of decks is not shown.
How the 21+3 Side Bet Works
The 21+3 bet uses your first two cards and the dealer’s first card, and treats them like a three-card poker hand. The board on the left lists the payouts, from a flush at 5 to 1 up to a suited three of a kind at 100 to 1. You can play the main hand without the side bet.
| 21+3 hand | Pays |
|---|---|
| Three of a kind (suited) | 100:1 |
| Straight flush | 40:1 |
| Three of a kind | 30:1 |
| Straight | 10:1 |
| Flush | 5:1 |
Placing Bets and Playing a Hand
Choose a chip, click the main circle and press Deal. Under the table you also get Double, Undo and Clear while you bet. After the cards come out you choose Hit, Stand or Double, and the game asks you to confirm when you stand on a low total. After a round, a Rebet & Deal button repeats your bet in one tap.
Strategy and House Edge
On the main hand, basic strategy keeps the edge low. Side bets such as 21+3 carry a higher house edge than the main game, so treat them as an extra rather than a way to win. We did not use the side bet in our test and stood on every hand, which is a weak strategy.
Demo Test Results
We played a short sample of hands at $1 on the main bet. The sample is small and the strategy was deliberately simple, so it says little about the long run.
Who Should Try Blackjack 21+3
It suits players who like classic blackjack with an optional poker-style side bet and a low minimum bet. Try the demo to see how the side bet pays before you risk real money, and keep the main hand as your focus.
