Of course! “Bonus Buy” slots are a popular feature where you can pay a large upfront amount to instantly trigger a bonus round (like free spins or a special game), skipping the need to land the required scatters naturally.
Finding **free play (demo mode)** versions of these slots is a great way to understand the mechanic without risking real money. Here’s a comprehensive guide:
### What to Know About Free Play Bonus Buy Slots
1. **The “Buy Bonus” Feature is Usually Disabled in Demos:** This is the most important point. In almost all free-play versions, the **Bonus Buy button will be greyed out or unavailable**. Game providers do this to prevent players from experiencing the entire game’s potential without real money play, and to comply with regulations in some jurisdictions that prohibit simulating buys in demo mode.
2. **Your Goal in Free Play:** Use the demo to test the **base game volatility, feel, and graphics**, and to see what the bonus round *could* be like if you trigger it naturally. You’ll often start with a large fake credit balance (e.g., 10,000 coins) to spin for a long time.
3. **How to “Test” the Bonus Round in Free Play:** Since you can’t buy it, you’ll have to trigger it the traditional way by spinning. This can take a very long time on high-volatility slots. Be patient, or use the **autoplay feature** with a high number of spins.
### Popular Bonus Buy Slots to Look for in Free Play
You can find these on almost any major casino review site or game provider’s website. Search for “**
**High Volatility (Very Popular for Bonus Buys):**
* **Gates of Olympus / Sweet Bonanza (Pragmatic Play):** The pioneers of the modern Bonus Buy. Look for the “Feature Buy” option (disabled in demo).
* **Dead or Alive 2 (NetEnt):** Legendary for its high-risk bonus round. The bonus buy is typically disabled in demos.
* **Jammin’ Jars / Sugar Rush (Push Gaming):** Known for cluster pays and expensive but potentially huge bonus buys.
* **Mental (NoLimit City):** Extremely volatile with unique mechanics. Demo will not allow feature purchases.
* **Wanted Dead or a Wild (Hacksaw Gaming):** A western-themed slot with multiple bonus buy options.
**Medium-High Volatility:**
* **Wolf Gold / The Dog House Megaways (Pragmatic Play):** Relatively more affordable bonus buys.
* **Reactoonz 2 (Play’n GO):** A cluster pays game where you can buy the different feature stages.
### Where to Find These Free Play Slots
1. **Official Game Provider Websites:** Companies like **Pragmatic Play**, **Play’n GO**, **Push Gaming**, and **Hacksaw Gaming** often have “Game Showcases” or demo versions directly on their sites.
2. **Casino Review & Affiliate Sites:** These are your best bet. They host thousands of demos to attract players.

3. **YouTube:** Search for “**
### Key Questions to Answer in Free Play Mode (Since You Can’t Buy the Bonus):
* **How often does the base game pay?** Is it completely dead between bonuses?
* **What is the gameplay like?** Do you enjoy the mechanics?
* **How hard is it to trigger the bonus naturally?** This gives you an idea of the slot’s volatility.
* **Can you see what the bonus round looks like?** If you get lucky and trigger it, you can evaluate it.
### Final Warning & Advice
* **The Free Play Experience is NOT Indicative of Real Money Bonus Buys:** The adrenaline, cost, and potential reward of clicking a $100 Bonus Buy button cannot be replicated in demo mode. The demo is for learning the rules only.
* **Always Gamble Responsibly:** If you move to real money play, understand that Bonus Buys are high-risk, high-reward features. They can drain your bankroll very quickly. Set a strict budget and never chase losses.
**In summary: Look for the popular slots listed above on demo casino sites, but understand that you will be playing the base game to try and trigger the bonus naturally, as the “Buy Feature” itself will almost always be disabled in free play mode.** Enjoy testing!
