Understanding free spin bonuses

A free spin is a bonus reward that allows players to spin a slot reel without paying real money. It is common for online casinos to offer a predetermined number of free spins players can use on slot games often with a time limit.

Players must read their chosen casino’s free spin bonus terms and conditions. This is important because conditions like wagering requirements are essential in whether you can withdraw your earnings. Understanding bonus terms and conditions helps you choose the best slots site to offer you a free spin bonus offer.

Types of free spin bonuses

Free spins promotions can be offered separately, as a component of a welcome package, or as an extra feature inside a particular game. We’ll provide you with an overview of the most popular kinds of free spins offers in this area.

  • No deposit free spin bonuses provide new players with a certain amount of additional spins without asking them to make a deposit. Typically, offers like this might have conditions like email verification or a promo code.
  • Some deposit-based promotions give a certain amount of additional spins that may be used on any game or a list of pre-selected slots.
  • Specific symbols or combos might provide a set quantity of additional spins.
  • There are numerous online casinos that provide loyalty reward programmes that come with a variety of perks, including extra spins.

Factors to consider when choosing slots for free spin bonuses

Choosing the right slot is one of the most important things to do when trying to make the best of your free spin bonus. Below are major factors to consider when choosing slots:

Return to player (RTP) percentage

Return to player measures how much money a slot machine is expected to pay back to a player over time. RTPs are expressed in percentage. Choose slots with higher RTP percentages–they offer better payouts in the long run.

Contribution towards wagering requirements

The wagering requirement is how many times you must bet your casino bonus before you can withdraw your winnings. Online casinos often allocate different contribution levels to casino games’ wagering requirements, this means not all casino game stakes will contribute 100% to the wagering requirement.

Slots commonly feature 100% contribution to wagering requirements, but confirming this information in the free spin bonus terms and conditions is important. Choosing a slot game with a high contribution percentage to your wagering requirement helps you clear the bonus more efficiently.


Volatility which is also referred to as variance or risk level determines how much risk is related to a slot game. It indicates how frequently you can expect a win if you choose to play. High volatility means bigger payouts with less frequent wins; low volatility means lesser payouts with more frequent wins.

Your play style and risk appetite should be considered when choosing based on volatility. High volatility slots are more advantageous for free spin bonuses since they offer higher potential winnings.

Maximum bet limit

Players must pay close attention to the maximum bet limit for any slot game they choose. Some online casinos restrict your maximum bet size when using free spins. Take note of this limit–exceeding them can lead to your bonus getting cancelled, and your winnings will be forfeited.

Choose casinos that enforce you stay within your permitted limit, this ensures you can use your free spin bonus effectively without violating terms and conditions.


The slot game you’re choosing must be compatible with your device. Some players love to play slot games only on their mobile devices. However, not all slot games are well-optimized for mobile devices. Players must check that the slot game is well-optimized for their chosen device before they choose any slot for their free spin bonus.

Why device optimisation is important

Choosing a slot game that is poorly optimized with your device can affect both your gambling experience and clearing the wagering requirements for the free spin bonus.

Strategies for maximizing your chances of winning with your free spin bonus

  • To ensure you comprehend the criteria and get the most out of your incentive, read the general terms and conditions.
  • Begin with a little wager and progressively raise it. We advise starting with the least stake allowed unless you are a high roller or an experienced gambler.
  • Pick slots that have a high payout percentage and less volatility. The payout percentage of the top slot machines is often greater than 96%.
  • Try out more slot machine variations, including video slots, bonus buy slots, megaways, and jackpot slots. However, confirm that there are no gaming limits imposed by the promotion.
  • Utilise your 50 free spins before the clock expires. You could only have 24 hours to utilise your free spins once you claim them, for instance.
