The Persistent Collector will land with a value of his own and will collect all other values from the screen, adding them to the total payout. This feature occurs on each spin.
The Persistent Payer will reveal a bet multiplier and add it to all other symbols on the screen, which happens on each spin.

Our Tips for Buying the Bonus Feature on Online Slots
Slot games where you can buy the bonus feature (often called “Buy Feature” slots) allow players to bypass the base game and jump straight into the bonus round for a specific cost. Here at onlinecasinos.net, we all enjoy buying the bonus feature. However, it is not without risk, so here are our tips for playing these types of slots:
- Understand the Costs: Before buying a bonus, ensure you’re fully aware of the cost. It can be a significant multiple of your base bet, sometimes 50x, 100x, or more.
- Budget Accordingly: Because the buy-in can be hefty, ensure you have set a budget for your session. It’s easy to get tempted and purchase multiple bonuses, which can quickly deplete your bankroll.
- Know the Game: Each slot game is unique. Before buying in, familiarize yourself with the game mechanics, paytable, and potential bonus outcomes. The more you understand, the better decisions you can make.
- RTP Can Be Different: Some games offer a higher Return to Player (RTP) percentage when you buy the bonus compared to playing the base game. Check the game’s info or paytable to see if this is the case. You can see a list of the different slot game providers, with links to each slot they offer, and RTP.
- No Guaranteed Wins: Even though you’re paying to enter the bonus round, there’s no guarantee of a big win. Like all slot outcomes, the results are random.
- Utilize Free Play: If the casino offers a demo or free play mode, use it to get a feel for the bonus round before spending real money. You can find the best free demo slots here
- Don’t Chase Losses: If you buy a bonus that pays out less than you hoped, don’t immediately buy another one trying to win back your money. This can lead to a quick spiral of losses.
- Set Limits: Decide beforehand how many bonuses you’ll buy and stick to that limit. Whether it’s a set number of purchases or a monetary amount, having a boundary can prevent overspending.
- Stay Informed: Game providers always develop new features and twists to the “Buy Feature” mechanism. Stay updated on slot reviews and casino news to learn about the latest games and strategies.
- Gamble Responsibly: Always remember that slots, including those with buy features, are games of chance. Never spend more than you can afford to lose, and seek help if you feel you might have a gambling problem.
Lastly, enjoy the experience! The buy feature provides entertainment and the thrill of the bonus round without the wait. Play wisely and have fun.
