Casino Terms Glossary
Split — is a casino term with two main uses: in blackjack, to divide a matching pair into two separate hands with an extra, equal bet; in roulette, a split bet covers two adjacent numbers with one chip and pays 17:1. In poker, a split pot divides winnings among tied players.

Understanding Split
In gambling, Split meaning changes by game but always involves dividing value. The Split definition in blackjack is a strategic option that can lower the house edge when used with basic strategy, especially with pairs like 8‑8 or A‑A. In roulette, a split bet trades hit frequency for a 17:1 payout. Knowing when to split shapes bankroll use, variance, and long-term results.

Examples of Split
Here are common examples showing how Split works:
- Blackjack: You hold 8-8 versus a dealer 6 and split, placing a second bet equal to your original; you now play two hands starting with an 8 each.
- Blackjack: Split A-A; most casinos give one card per ace, no resplit or double, but it outperforms hitting.
- Roulette: Place a split on 17/20 by dropping a chip on the line between them; if either hits, it pays 17:1.
- Poker: Final board shows a straight for both players; the pot is split because hands tie.
FAQs
What is Split in blackjack, and when should a player use it?
Split in blackjack means turning a pair into two hands by matching your original bet. Use it according to basic strategy: always split A‑A and 8‑8; never split 5‑5 or 10‑10; other pairs depend on dealer upcard and table rules. Correct splits reduce the house edge and smooth variance.
How does a roulette Split bet work and what is the payout?
Place a chip on the line between two adjacent numbers on the layout to cover both. European and American roulette pay 17:1 on a winning split, with a 2/37 or 2/38 hit chance respectively. It’s a middle‑ground bet between straight‑up and street/corner coverage in risk and frequency.
Can splitting pairs increase my chances of winning in gambling?
Proper splits in blackjack improve expected value versus hitting or standing in many situations, especially with A‑A and 8‑8. They don’t guarantee profit but optimize odds over time. In roulette, a split doesn’t change house edge; it just alters variance and coverage. Always size bets within your bankroll.
Is a Split the same as a split pot in poker?
A casino term can vary: Split in blackjack or roulette is a player action, while a split pot is a rules outcome when tied hands share winnings. Both divide value, but only blackjack/roulette splits are choices. Understanding the context clarifies Split definition and avoids miscommunication at the table.
Do table rules change the Split definition or strategy?
Yes. Blackjack rules—resplitting aces, double‑after‑split (DAS), hit/stand on soft 17—affect optimal splits and house edge. Some casinos limit resplits. Always check the table placard or a trusted casino review. 101RTP highlights rule sets in reviews so you can align strategy with conditions before you risk your bankroll.
Why does Split meaning matter for bankroll management?
Split decisions change volatility and exposure. In blackjack, splitting doubles your stake and can create multiple active hands, increasing short‑term swings while often improving long‑term EV. In roulette, a split lowers variance compared with straight‑ups by covering two numbers. Plan unit sizes so splits fit your limits.
