Quick answer: There is no blackjack welcome bonus among our five. Take wager-free spins and play blackjack with your own cash, or decline.
Why not
| Game | House edge | Typical contribution |
|---|
| Slots | Around 4% | 100% |
|---|
| Blackjack | around 0.5% with good rules | 0% to 20% |
|---|
A bonus is priced on the house edge. At around 0.5% with good rules, clearing one on blackjack would cost almost nothing, so casinos exclude it or count a fraction.
Live blackjack
Live blackjack is treated the same way. Blackjack is the cheapest casino game there is, which is exactly why it is the first to be excluded.
If you play blackjack anyway
| Rule | Better | Worse |
|---|
| Blackjack pays | 3 to 2 | 6 to 5 |
|---|
| Dealer on soft 17 | Stands | Hits |
|---|
| Doubling | Any two cards | Restricted |
|---|
A 6 to 5 table adds more than a percentage point to the house edge, which is more than most bonuses are worth to a careful player. Follow basic strategy: stand on 17 or more, hit 12 to 16 against a dealer 7 or higher, always split aces and eights.
Side bets and insurance
Both carry edges many times the main game's. With or without a bonus, leave them alone.
