Casino Terms Glossary
Double — is a gambling action or outcome where a wager or payout is increased to twice its original value. In casino play it most often refers to doubling down in blackjack, using a double-up gamble in slots, or hitting dice doubles in craps, each with distinct rules, risks, and expected value.
Understanding Double
In gambling, Double meaning varies by game, but the core idea is the same: you accept higher risk for a potential 2x return. The Double definition covers three common uses: blackjack double down after the first two cards, slot double-up gambles after a win, and dice doubles in craps that trigger specific bets. Knowing when to double affects house edge, variance, and bankroll safety. At 101RTP, you’ll find reviews and tools (Slot Simulator, Bonus Value Score) to test scenarios and pick casinos and games that fit your strategy.
Examples of Double
Here are practical examples of how Double appears across casino games:
- Blackjack: You hold 11 versus a dealer 6 and double down, adding an equal bet and drawing one card because odds favor a strong total.
- Slots: After a 5-coin win, you take the double-up gamble; a correct red/black guess pays 10 coins, a wrong guess returns zero.
- Craps: You place a Hard 8; it wins only if a double 4–4 appears before an easy 8 or a 7.
- Pressing bets: A player doubles the next wager after a win to capitalize on momentum, increasing volatility without improving true odds.
FAQs
What is Double in casino gambling?
In casino terms, Double is an action or outcome that pushes your wager or payout to 2x. It most often means doubling down in blackjack, using a slot double-up gamble after a win, or dice doubles in craps that affect certain bets. It increases variance and requires smart bankroll management.
How does Double meaning change across games?
Double meaning differs by rules. Blackjack doubles add one card after matching your stake. Slot double-ups are 50/50 gambles that risk the recent win. In craps, doubles (like 3–3) matter for hardways and prop bets. Read each game’s house rules to know eligibility, payouts, and risk.
Can using Double improve my expected value?
Doubling can improve EV only in specific spots, like optimal blackjack double downs (e.g., 11 vs dealer 6). Slot double-ups are typically neutral or slightly negative due to game edge; craps doubles depend on bet type. On 101RTP, we break down EV by game so you can decide when doubling makes sense.
Is the Double-up feature on slots worth it?
The slot Double-up is high-volatility entertainment. It doesn’t change the machine’s long-term RTP and can quickly erase small wins while occasionally boosting them. If your goal is bonus clearing or steady bankroll, consider skipping it; if you enjoy risk spikes, set strict limits and keep stakes modest.
Do casinos allow Double on every blackjack hand?
Rules vary by casino and table: some allow double on any two cards; others restrict to 9–11 or 10–11, and many limit doubles after splits. These rules change house edge and player options. Check the felt or rules placard to confirm what is permitted before you sit down.
Why should I learn the Double definition before using it?
Knowing the Double definition helps you avoid negative-EV spots and tailor your gambling plan. Understand when doubling increases profit and when it just amplifies swings.
