What happens during a bonus round in an online table game like blackjack and how does it change the standard rules?

Bonus Elements that modify your bet mid-hand

The closest thing to a true "bonus round" in modern online blackjack is a pre-deal bonus element that activates before cards are even distributed. Some variants combine traditional blackjack rules with a Bonus Element that dynamically boosts the main bet — after betting closes and before cards are dealt, the Bonus Element appears with a random rank. Matching that rank on your opening hand adds the Bonus Element's value directly to your wager, which then carries through actions like Double and Split. In practice, this means the core blackjack rules (hit, stand, double, split) remain completely intact — the "bonus" is purely a wager multiplier, not a separate game mode.

Side bets: the more common "bonus" layer

What many players call a bonus round in blackjack is actually a side bet — a parallel wager resolved independently of your main hand. These don't change how the main game is played; you still get two cards, still aim for 21, and the dealer still follows the same fixed rules. The side bet just adds a second outcome riding on the same cards. A few examples you'll find on Ontario-registered platforms: - **21+3** is a side bet where your first two cards and the dealer's face-up card must combine into an eligible three-card poker hand for you to win. - **Blazing 7s** can be placed after making a standard blackjack bet — if at least one of your first two cards is a 7, you win on the side bet; two 7s pays even more. Each Blazing 7s side bet contributes to a progressive prize pool, and depending on which 7s you receive, you can qualify for a portion of or the entire progressive prize. - **Insurance** is a side bet that the dealer has blackjack, treated independently of the main wager. It pays 2:1 and is offered when the dealer's up card is an Ace — essentially a bet that the dealer's hole card is worth 10. The key thing to understand about all these: the side bet can only be placed after making a standard blackjack bet, and losing it doesn't end your main hand.

Variants that actually rewrite the rules

Some blackjack titles go further and structurally change how the game works — which is closer to what most people imagine when they hear "bonus round." In standard blackjack you have to double your wager to split or double down. In Free Bet Blackjack, these options are offered on the house — with a special button representing your second wager — and if you win, you get paid as if you doubled your initial bet. The catch that balances this out: the dealer pushes on totals of 22 instead of busting, which shifts the house edge back in the casino's favour. Blackjack Switch requires players to make two bets of equal size before receiving two sets of cards; once dealt, players can switch the two secondary cards between hands to get as close to 21 as possible. If a player switches to a blackjack, it counts as 21 points rather than a "natural" — meaning it doesn't win automatically the way a standard blackjack does.

The house edge angle — worth knowing

Every bonus or side-bet layer comes with its own house edge, typically higher than the main game's. By following basic strategy — making correct choices to hit, stand, double, and split — players can reduce the house edge on the main hand to around 0.5%. Side bets rarely offer odds that good, so treating them as entertainment rather than a strategy play is the more grounded approach. No matter how well you play, you can't eliminate the house advantage, and even the best players can lose over time. Always check the paytable and rules panel for the specific title you're playing — these details vary by game and by operator. Stick to platforms registered with iGaming Ontario (look for both the iGaming Ontario and BetGuard logos on the site).
