Quick Takeaways
- Side bets usually increase volatility because they add higher-variance outcomes to your session.
- Even small side bet amounts can dramatically change bankroll swings when played frequently.
- If you use side bets, treat them as entertainment, keep them small, and never chase.

What “Volatility” Means in Blackjack
Volatility is how “swingy” your results feel over a session.
Two games can have similar long-run cost, but:
- one feels smooth
- the other feels like a roller coaster
Blackjack is usually medium volatility because:
- many hands resolve with small wins/losses
- your decisions (hit/stand/double/split) shape outcomes
- you don’t usually get massive jackpots from the base game
Side bets change that. They inject “lottery-style” outcomes into a game that normally isn’t built that way.
Why Side Bets Increase Volatility
Side bets increase volatility for three reasons:
1) They Add More Bets Per Round
Your session isn’t just “main bet outcomes” anymore.
It becomes:
- main bet + side bet + side bet + side bet…
That increases total money at risk each round.
Even if your side bet is small, playing it every hand increases exposure fast.
2) Side Bet Outcomes Are High Variance
Most side bets pay rarely and pay big when they hit.
That means:
- long stretches of small losses
- occasional spikes that feel exciting
- and a strong psychological pull to keep trying
This is the exact structure that creates chasing behavior.
3) Side Bets Increase Emotional Pressure
Side bets create a second “win story” in your head:
- “I’m losing blackjack, but I’m close to hitting the side bet.”
- “I’m due for a Perfect Pairs hit.”
That thinking leads straight into gut feeling play.

Side Bets Also Increase “Risk Per Hour”
This is the part most players miss.
If you play a side bet every hand, you’re increasing your total risk per hour because:
- you’re wagering more per round
- and you’re doing it many times per session
This effect is even stronger online because games move faster.

A Simple Example: How a Small Side Bet Becomes a Big Leak
Imagine:
- your main bet is steady
- you add a small side bet “just for fun” every hand
Even if the side bet is a small fraction of your main bet, the repeated frequency means:
- the side bet becomes a consistent cost stream
- and the wins come in spikes, not steady returns
That creates the feeling of:
- “I’m almost there”
even while your bankroll is draining.
Side Bets Can Make You Forget the Main Game
This is a hidden risk.
When side bets become the focus, players often:
- stop thinking clearly about basic strategy
- rush main-hand decisions
- double or split emotionally because the side bet “didn’t hit”
- raise their main bet to “support” side bet chasing
This is where a side bet turns into a session killer.

How Side Bets Affect Bankroll Management
If you include side bets, your bankroll plan must change.
Because your session is now more volatile, you need:
- a larger bankroll buffer
- a smaller base bet
- stricter stop-loss rules
- shorter sessions

When Side Bets Can Be “Okay”
Side bets aren’t automatically evil. The problem is how people use them.
Side bets can be reasonable when:
- you treat them as entertainment
- you keep them small (relative to your bankroll)
- you don’t play them every hand
- you never increase them to chase
A simple rule:
If you’re emotionally attached to the side bet, you shouldn’t be playing it.
Common Side Bet Traps to Avoid
Here are the biggest traps:
- Auto side bet toggles (you forget it’s on)
- “I’m due” thinking (pattern myths)
- raising stakes after a miss
- adding side bets during losing streaks
- playing side bets at fast tables (too much volume)

The Best Approach for Most Players
If your goal is better odds and cleaner play, the best approach is usually:
- focus on table rules (3:2, S17, doubles, surrender)
- play close to basic strategy
- keep betting stable
- treat side bets as optional entertainment, not a plan
