I understand you’re asking about “buying bonus slot machines.” This is a term that can mean a few different things in the world of gambling and gaming. I’ll explain the most common interpretations and provide important context.
### 1. **”Buy-a-Bonus” Feature in Modern Slot Machines**
This is the most common meaning. It’s a feature in many video slots, both online and in physical casinos.
* **What it is:** Instead of waiting for the bonus round (free spins, pick’em game, etc.) to trigger randomly, you can pay an extra amount (usually 50x to 100x your bet) to **purchase** or **guarantee** entry into the bonus game on the next spin.
* **How it works:** A button labeled “**Buy Bonus**,” “**Feature Buy**,” or “**Bonus Bet**” appears on the screen. The cost is clearly displayed.
* **Pros:** Saves time, provides immediate excitement, and allows you to play the most entertaining part of the game.
* **Cons:** It’s expensive. The cost is calculated based on the long-term average value (RTP) of the bonus. You pay for the *chance* at a big win upfront, but the outcome is still random. You can often lose the extra money quickly.
### 2. **Purchasing Physical Slot Machines for Personal Use**
This refers to literally buying a slot machine unit.
* **Legality:** This is heavily regulated and varies by country, state, and province. In many places, you can only own **antique** machines (typically pre-1940s) or **decommissioned** machines that have been modified for legal private use (e.g., made for tokens/candy, or disabled for gambling).

* **Sources:** Specialty retailers, auctions, and online marketplaces sell “for amusement only” machines. **Never buy a functional, current-model slot machine from an unauthorized seller—it’s likely illegal.**
* **Considerations:** They are expensive, heavy, and may require technical knowledge to maintain.
### 3. **In-Game Purchases in Social/Casino Apps**
In free-to-play social casino apps (like Slotomania, Heart of Vegas), you can buy virtual coins or bundles that include “bonus slot machine” spins or access to special machines. This is for entertainment with no cash payout.

### **Critical Warnings & Responsible Gambling**
1. **The House Always Has an Edge:** Whether you buy a bonus or play normally, slot machines are games of chance with a built-in house advantage (RTP < 100%). Buying the bonus doesn't improve your odds of a positive outcome in the long run. 2. **Higher Volatility:** Buying a bonus usually means paying for a high-volatility experience. You might get a big win, but you are also very likely to get a bonus that pays less than the purchase price. 3. **Budgeting is Essential:** If you choose to use the "Buy Bonus" feature, **always set a strict loss limit beforehand**. It's a fast way to spend your bankroll. 4. **Legality:** Ensure any form of gambling you engage in is legal in your jurisdiction. Never attempt to buy a live casino slot machine without verifying ownership laws. ### **Bottom Line:** If you're a player, "**buying a bonus**" is a paid shortcut to the feature round of a slot machine. It's designed for entertainment and convenience, not as a profitable strategy. **Use it sparingly and only with money you can afford to lose.** If you're interested in **owning a physical machine**, prioritize researching your local laws first, then seek out reputable dealers of antique or "amusement-only" units. **Please gamble responsibly.** If you feel you or someone you know may have a gambling problem, seek help from organizations like the National Council on Problem Gambling (1-800-522-4700) or Gamblers Anonymous.
