What Is a Bonus Buy Slot?
Some slots allow players to dive straight into the bonus round โ for a fee. These are normally known asย bonus buy slots, but they may be referred to asย buy feature slots. The cost to access the bonus round will typically be a multiple of your bet amount.
For example, it is 85x your bet when you playย MontezumaMegaways. If your bet size is $2, you will need to pay $170. The bonus round will then begin straight away. You will receive a series of free spins, and any wins you earn will be multiplied. At the end of the round, your total winnings will be revealed.
You can also sometimesย land symbols that decrease the bonus buy amount. Letโs say it starts at $100. If you play 50 spins and land the $1 decrease symbol 20 times, the bonus buy would be decreased to $80, plus youโd have whatever you won along the way.
Slot Bonus Symbols
The best online slots feature at least one bonus round. Unless you use the bonus buy feature, youโll typically need toย land at least three scatter symbolsย during the base game to trigger the bonus round. These are some of the benefits you can unlock.
- Free Spinsย | You will normally receive several free spins during the bonus round. Here are the bestย free spins casino bonuses.
- Multipliersย | Any wins you earn during the bonus round will often be multiplied.
- Extra Spinsย | Some slots allow you to earn additional free spins during the bonus round if the scatters appear, so the free spins are essentially retriggered.
- Pick and Clickย | In this bonus round, you will be presented with a series of items to choose from, such as locked treasure chests. Select one, and your prize will be revealed.
- Wheel of Fortuneย | Spin the wheel during the bonus round to win cash prizes, multipliers, or access to other bonus features.
- Trail Bonusย | Progress along a path by rolling a die or spinning a wheel, and unlock cash prizes, multipliers, and other rewards along the way.
Bonus Buy Strategy
Follow these tips to boost your chances of success when playing bonus buy slots.
- Activate the buy bonus feature if it will reduce the house edge.ย For example, Montezuma Megaways typically has a house edge of 4.08%, but that drops to 3.83% when you use the buy bonus option. In that case, it would be advantageous to activate the buy bonus feature.
- Select the right bet size.ย You often need to pay a large multiplier to buy your way directly into the bonus round. For example, it might be 100x your bet. If you like to wager $20 per spin, reduce the bet size to $0.20, and you can then pay $20 to dive straight into the bonus round.
- Play in demo mode.ย If you activate the bonus buy option, your goal will be to earn enough money to cover the fee you paid and generate an overall profit. Play the slot for free in demo mode to see how often you achieve that goal before you consider playing for real money.
- Claim bonuses.ย The best sites offer excellentย no deposit bonusesย and lots of ongoing promotions. They give you the chance to play bonus buy slots with house money. Make sure you claim all the available bonuses at your online casino.
- Gamble responsibly.ย The cost of activating the bonus buy feature is often high, so there is a risk of exceeding your budget when you play these games. For that reason, it is essential to follow responsible gambling principles. Do not play with money you cannot afford to lose, and do not chase losses. Consider setting bet limits and deposit limits on your own account, as that can help you stay on track.
