Every gambler has been there: you sit down with $200 and think, “If I could just walk out with $400, that would cover dinner and the show.” The problem is that most players try to double their money by chasing long-shot bets or playing games with a high house edge. If you want to actually flip your bankroll, you need to stop playing for entertainment and start playing with a strategy. The best way to double your money isn't about finding a “loose” slot machine; it’s about math, volatility, and knowing exactly which games offer the shortest path from Point A to Point B.
The Math Behind Doubling Your Bankroll
To double your money, you have to accept a fundamental truth: the casino always has an edge. Your goal is to minimize that edge while maximizing your volatility. High volatility means you have a better chance of hitting a big win (doubling up) but also a higher chance of busting out quickly. Low volatility games like penny slots will grind you down slowly, making it nearly impossible to hit a 100% profit without hitting a jackpot.
The most efficient way to double a small to medium bankroll is often to make fewer, larger bets rather than hundreds of small ones. This concept, known as “bold play,” suggests that making a single large bet on a game with a low house edge gives you a statistically better chance of hitting a specific monetary goal than grinding it out. If you bet your entire bankroll on one hand of Blackjack, you have nearly a 50% chance of doubling up instantly. If you split that money into 100 slot spins, the house edge compounds, and your chances of doubling drop significantly.
High RTP Table Games for Maximum Returns
If you are strictly looking to double your money, table games are your best friend. While slots offer the dream of a life-changing multiplier, table games offer the consistency needed for short-term goals.
Blackjack: The Player’s Best Bet
Blackjack remains the gold standard for doubling your money. With a house edge as low as 0.5% when you apply basic strategy, you are getting close to a coin-flip scenario. The key here is to avoid side bets like “21+3” or “Perfect Pairs.” These bets have house edges often exceeding 5% and will drain your bankroll before you get a chance to double it. Stick to the main game, find tables that pay 3:2 on blackjack (avoid 6:5 tables at all costs), and use a strategy chart. If you start with $200, finding a $25 or $50 minimum table allows you to weather a few cold hands while still having the opportunity to press your bet when the count—or luck—turns in your favor.
Baccarat and Craps Options
Don’t want to make decisions that affect the outcome? Baccarat is your answer. Betting on the Banker has a house edge of just over 1%. It is one of the simplest ways to try and double your money: you bet, the dealer deals, and you either win or lose. There is no skill involved, which removes the risk of making a “bad play.”
Craps is another excellent option, specifically the Pass Line and Come bets. The Pass Line has a house edge of 1.41%. However, the real power of Craps comes from taking odds. The Odds bet is the only wager in the casino with a 0% house edge. By combining a Pass Line bet with maximum odds, you dilute the overall house edge on your total wager, bringing you closer to a 50/50 shot at winning big.
High Volatility Slots vs. Low Variance Games
If table games feel too slow or intimidating, you can try to double your money on slots, but you must choose the right type. You should not be playing low variance games like Starburst or Blood Suckers for this goal. These games pay out small wins frequently, keeping your balance steady, but they rarely pay out 2x your total buy-in without a massive stroke of luck.
Instead, look for high volatility slots. Games like Dead or Alive II or Book of Dead are designed to eat small balances for long periods before potentially erupting with a massive payout. This is a high-risk strategy. You might lose five deposits in a row, but when you hit a bonus round on a high-volatility slot, doubling your money is the minimum you can expect—often, you walk away with 10x or more. Just remember, for every player who doubles up on a high-volatility slot, several others bust out in minutes.
Using Casino Bonuses to Hedge Your Bets
One of the safest ways to double your money is to use the casino’s money to do it. Welcome bonuses and deposit matches give you extra ammo, which changes the math significantly.
| Casino | Welcome Bonus | Wagering Requirement | Min Deposit |
|---|---|---|---|
| BetMGM | 100% up to $1,000 | 15x Bonus | $10 |
| DraftKings Casino | 100% up to $1,000 | 15x Bonus | $5 |
| Caesars Palace Online | 100% up to $1,250 | 15x Deposit + Bonus | $10 |
| FanDuel Casino | Play $1, Get $100 in Casino Credits | 1x Playthrough | $1 |
By taking a 100% deposit match, you are effectively doubling your bankroll before you even place a bet. Let’s say you deposit $100 and get a $100 bonus. You now have $200 to play with. If you play a high RTP game like Blackjack (though check the contribution percentages—usually 10-20%), or even a medium volatility slot like Divine Fortune, you have a much larger buffer to hit a winning streak. The FanDuel offer is particularly interesting because the playthrough requirement is just 1x, meaning once you play through the bonus credits once, anything left is cash you can withdraw. This is arguably the closest thing to a “risk-free” double you will find.
Bankroll Management Strategies
You cannot double your money if you run out of cash. This is where the “stop-loss” and “win-goal” concepts come into play. Before you log in to a site like BetRivers or Hard Rock Bet, decide exactly what you are willing to lose. If your goal is to turn $200 into $400, you need to set a stop-loss at $200 (your starting amount) and a win-goal at $400.
Here is a practical approach: Divide your bankroll into units. If you have $200, one unit is $10. Do not bet more than 1-2 units per hand or spin. If you get up to $300, consider increasing your bet size slightly to $15 or $20 to accelerate the path to $400. However, if you drop back down to $250, lower your bet again. This “oscillation” strategy protects your winnings while giving you a chance to press your advantage when the cards or reels are hot. The biggest mistake players make is betting the same amount regardless of their current balance, or worse, chasing losses by doubling their bet size after every loss (the Martingale system), which usually leads to busting out on a bad streak.
FAQ
Can you really double your money at a casino?
Yes, it is possible, but it requires discipline and a bit of luck. The most reliable method is playing low house-edge games like Blackjack or Baccarat, or utilizing a welcome bonus to give yourself a larger starting bankroll. It is never guaranteed, and you should always be prepared to lose your initial stake.
What is the safest bet to double money?
The “safest” bet in terms of house edge is the Odds bet in Craps (0% house edge) or the Banker bet in Baccarat (approx 1.06% house edge). However, you usually need to make a base bet to access the Odds in Craps. Blackjack with perfect strategy is also extremely safe regarding house edge, hovering around 0.5%.
Does the Martingale system work for doubling money?
The Martingale system (doubling your bet after every loss) is dangerous. While it can work for short sessions, it requires a massive bankroll to survive a long losing streak, and you will eventually hit the table limit, making it impossible to recover losses. It is not recommended for casual players.
Can I use a bonus to double my bankroll?
Absolutely. A 100% deposit match bonus effectively doubles your bankroll instantly. For example, depositing $100 at BetMGM gives you $200 to play with. Just be sure to check the wagering requirements; a 15x playthrough is very manageable compared to the 30x-40x found at some offshore sites.
Are slots a good way to double your money?
Slots are a high-risk, high-reward option. Low volatility slots are bad for this goal because they pay small amounts. High volatility slots are better, but you risk losing your money very quickly. Slots should be a last resort if you are strictly trying to double a specific amount of cash.
