The gameplay feature has been developed recently in video slots. In 2017, Big Time Gaming released a game with a new bonus launch system: White Rabbit, based on the book about Alice in Wonderland. The slot came out with Megaways mechanics. Spins run on six reels, and the maximum number of ways to win is 248,832. But this was not the most interesting characteristic.
For the first time, the user got the opportunity to choose: wait for the bonus, or instantly activate it.
Players appreciated the novelty, and White Rabbit quickly hit the top lines of online casino ratings. The rest of the manufacturers have successfully adopted them, and such developments are now coming out more and more often.
How Purchased Casino Bonuses Work
The basic principle by which slots with the purchase of a bonus work is the same as in the usual ones. First, the player chooses the amount of the bet. If the number of lines is regulated, it sets their number. Then the rotation begins, and the result of the round becomes known. The prize function can be triggered in the usual way. You need to wait for a combination of scatters or other images to appear. The accumulative principle can operate in such devices. The bonus begins after the desired game situation is repeated several times.
A purchase can be made at any time in the main mode:
- The user clicks the corresponding button.
- The spin starts.
- The required combination falls out.
- The prize function is activated.
Often, when buying, you can choose additional conditions, for example, the number of free rounds and the value of the multiplier. The price of the option depends on this.
All slots with purchased bonuses exist in two versions. The paid game is for money. A person needs to register at an online casino and replenish an account. After that, you can place real bets.
The second version is free. It uses virtual loans. The client does not spend money and cannot withdraw the winnings. Usually these devices are available without registration. To start spinning, you need to select the “Demo” option at startup. The account will contain the amount of virtual credits. If they run out, you can start over after refreshing the page. The instant launch of the bonus in this mode allows you to immediately evaluate all the features of the video slot and understand whether it is worth playing for real money.
The function is important to distinguish from online casino promotions. Operators’ offers can be activated for replenishment of the account, but this money can be used for further bets and you can choose the machine from the available list at your discretion. The option provided by the provider is valid only for one video slot. The amount spent on the launch is not refundable, regardless of the further situation.
Advantages of Slots with Purchased Bonus
The main plus is that the user himself determines when to go to the bonus. He does not have to wait for the appropriate opportunity and spend money on bets for spins. Usually providers are not limited to one prize function. In addition to the bonus, which is launched for money, the video slot can have a risk game, respins, rounds on a separate screen, options that start randomly in the main mode.
What are the disadvantages
An instant bonus launch does not guarantee large prizes. It is impossible to say exactly how many spins will be empty. It all depends on the RNG. Analysis of RTP and volatility allows you to roughly imagine the frequency of combinations falling out and what the odds for them will be. But this only works in theory.
By choosing casino games with purchased bonuses, the user may use the function too often. But then there is a risk of losing large sums. For this reason, video slots of this type are prohibited in the UK. The launch cost is not always offset by the possible amount of the prize. Simply put, you shouldn’t get carried away with the frequent transition to the bonus if the game is not running in demo mode.
How to buy a bonus and how much does it cost
The purchase price is set by the manufacturer. It is calculated based on the total bet with a multiplier, and is usually x80-x100. If the cost of the bonus is higher, it is recommended to activate the function only in demo mode. The player runs the risk of spending more than the possible payout amount. A special control element is intended for purchase. It is often located to the left of the reels. By clicking on the button, the player will see a menu indicating the cost or buttons to change it.
