If you’re looking for a casino game that offers you a chance to win big prizes with a small stake and provides you with fun and thrill, then slots are the perfect choice. Slot machines are easy to play and understand and are available in various themes and features to suit your preferences.

One of the most appealing aspects of slot machines is the bonus rounds and free spins that they often feature. These are special mechanics that can enhance your gameplay and increase your winnings in any casino game you play online. This article explains what BR and FS are, how they work, and why they are so crucial to slot enthusiasts.

Bonus Rounds & Free Spins: What Do They Mean?

These are extra features triggerable by certain symbols or combinations on a slot’s reels. They usually offer more rewards and entertainment than the base game and may vary in type and complexity depending on the slot.

Promo rounds are mini-games that take place on a different or the same screen as the base game. They can involve picking items, spinning wheels, matching cards, shooting targets, or other interactive elements. Rewards for winning include cash prizes, multipliers, and jackpots.

Free spins are rounds that you don’t have to pay for. They are usually activated when you hit three or more scatter symbols on the reels but may also be awarded randomly. They can have rules and features different from the base game, such as higher payouts, more wilds, expanding symbols, sticky symbols, or cascading reels. FS can also be retriggered, meaning that you can get more bonuses during the feature.

Tips to Maximise Bonus Rounds and Bonus Spins in Slots

While promo rounds and spins can have a big impact on your slot gameplay experience, they are not a guarantee to happen. So it’s necessary not to lose your head when you play. The tips below will help optimise your chances with these features.

  • Choose slots with high RTP (return to player) and low volatility. These slots tend to pay more frequently and consistently, meaning you can play longer and have more opportunities to trigger the features.
  • Bet within your budget and adjust your bet size according to your balance. You don’t want to run out of money before you land an extra feature. When you have the money, betting enough to qualify for the maximum payouts and jackpots is advisable.
  • Read the paytable and the rules of the slot. You must be able to identify what symbols and combinations will activate these features and the rules guiding their use. Also, be sure of the minimum and maximum bets, the number of paylines, and the special symbols and functions.
  • Have fun and enjoy the game. Promotional rounds and spins are meant to add more excitement and entertainment to your slot machine experience. Don’t get frustrated or obsessed with them. And don’t chase them with more money than you can afford to lose. Remember that slot machines are games of chance, and the outcome is random and unpredictable.
