Let’s start from the beginning: What are bonus buy slots?

If the answer to the can you buy bonus on slots question is yes, then you are playing bonus buy slots. All online casinos (except live dealer online casino sites) offer slot games and almost all of them have a bonus feature.

For example, to activate the free spins round, you need to find three scatter symbols. In other words, it is entirely up to chance whether you can start the bonus feature or not.

Slots to buy bonus works differently. In these games, you can start the bonus feature (for example, the free spin round) at any time by paying. The payment amount is determined according to the bet amount.

As long as you have sufficient funds, you can repeat the purchase as many times as you want. So bonus buy slots are no different from other slot games: You can still activate the bonus feature normally. They only offer the option to buy the bonus whenever you want.

The situation of bonus buy feature slots in the UK

You may have seen the “bonus buy slots banned” news in the media: This news is true but it only concerns online casinos licensed by The United Kingdom Gambling Commission (UKGC).

You can still play real money no deposit slots in these casinos and take advantage of different types of casino bonuses), but it is not possible to play buy bonus round slots. These games can only be played without the “buy” feature.

The bonus buy slots UK decision was made in the last months of 2019, and the official justification was that “the players spend 100 times more money on bonus buy slots.”

In other words, the bonus buy feature slots are banned under responsible gaming practices. This decision not only attributes British players, but all UKGC licensed online casinos.

Are bonus buys on slots restricted in other countries too?

There is currently no other licensing agency or jurisdiction banning bonus buy slot games. It is still possible to play bonus buy slots in online casinos that do not have a United Kingdom (UKGC) license.

However, we do not know how long this situation will continue: Historically, the MGA (Malta Gaming Authority) almost always followed the UKGC decisions. Therefore, bonus buy slot machines can also be banned in MGA licensed casinos too.

1) Iron Bank: Developed by Relax Gaming, this video slot contains 6 reels and 4.096 betlines. It also offers three different features. First, you will see random “mystery” symbols on the reels during the main game. These slot machine symbols can transform into any other symbol. Second, random bonus symbols (1 to 3 scatters) will be placed on the reels any time during the main game. Third, any reel can be filled with wild symbols (up to 3 reels) during the, you guessed it right, main game. The RTP rate is 96.20% and this is a high variance slot: You can expect quite big rewards, which makes Iron Bank one of the best payout slots.

2) Crystal Prince: Quickspin used quite innovative mechanics in this game: You start playing with 6 reels, 4 rows, and 4.096 betways. However, you can unlock the “Blizzard” mode by winning a spin, and each win adds a new row to the game screen. It is possible to increase the row count to 8, and when this happens, you start playing with 262.144 betlines. The game uses the “cascade reels” feature, which means after scoring a win, all symbols that are part of that win disappear from the reels and new ones drop down from above. This is one of the best free online slots with bonus you can play.

3) Aztec Gold Extra Gold Megaways: iSoftBet used a really long name for this game but it is easy to remember: You just need to repeat “gold” two times. Aztec Gold is a very new game; it is released in September 2020. The game contains 6 reels, 7 rows, and 117.649 betlines in total. The minimum bet is only 0.20 coin and the RTP rate is 96.00%.

This game features 6 reels, 4 rows, and 4.906 paylines. The “Mystery Sandstorm” feature can be triggered at any time while playing the game. This feature adds 1 – 4 mystery symbols to the reels, which will transform into a random symbol. When you land two “treasure hunter” symbols to the reels, the free spin round will start. During this round, mummies will start to walk on the reels and if they meet each other, you will win one sticky wild and one more free spin. You start the round with 6 spins but this number can increase easily.

5) Titan Thunder Wrath of Hades: Another bonus buy slot with a really long name. This one comes from Quickspin and features 5 reels, 3 rows, and 25 betlines. Titan Thunder is not a “Megaways slot” game: It is a good old video slot that offers you the chance to win up to 10.000x total bet with a single spin. There is also a “Lightning Jackpot Respins” feature: You can start it by landing 6 money symbols anywhere on the screen. Doing so gives you 3 free re-spins with sticky symbols. Each money symbol that lands during these spins increase the multiplier value by one, up to 14x. However, if you manage to land jackpot symbols, you can win up to 1.000x total bet too.

6) Queen of Hearts Megaways: Megaways are a common feature in the bonus buy slots, and this one is no exception: One of the most recents Alice in Wondertland slots developed by iSoftBet, Queen of Hearts contains 6 reels, 7 rows, and 117.649 lines. It is based on the “Alice in Wonderland” tale, as can be guessed, and offers an RTP rate of 96.20%. The variance is high, so this is one of the best real money slots you can play if you like big payouts. You can win up to 35.000x total bet and there are mystery symbols in this one too: Time to time, mystery symbols will be placed on the reels and transform into random symbols, which can help you to complete a winning combination.

7) Demi Gods III: This is a classic video slot with 5 reels and 45 betways. Demi Gods III is developed by Spinomenal and offers a 96.20% RTP. It offers many features: The wilds are sticky, the symbols can stack, and there are multiplier payouts. You can win 12 free spins with the “Synchronizing Reels” feature. This means the symbols on different reels can change places and match each other, which increases your winning chance. During the main game, you can also take advantage of the “Random Wilds” feature, which adds random wild symbols on the reels. The minimum bet is only 0.50 coins, so you can play this one for a long time, especially if you take advantage of a desktop or mobile casino bonus.

We recommend playing this one in a 200 match bonus casino so you can start with a big bankroll.

9) Gems Bonanza: This one is an unusual slot developed by Pragmatic Play. It uses an 8×8 layout, which means there are 8 reels and each reel contains 8 symbols. And there are no betlines. That’s right: Gems Bonanza does not use any paylines. Instead, 64 gems drop with every spin and you try to create clusters that contain 5 – 25 symbols to win. In a way, it is similar to a match-3 game. There are also “Mega Symbols” that can fill the entire screen. Collected symbols will fill a “Gold Fever” meter and when it is full, you trigger the free spins round with multipliers. It is possible to win up to 100x total bet during this round.

10) Mermaid Reef: Mermaid Reef comes from Reel Play and offers 5 reels, 3 rows, and 10 betlines. In other words, it is a classic video slot. Its bonus feature is called the “Pearl Bonus” and this is a pick me game where you try to find multipliers by clicking on closed pearl symbols. It is possible to win up to 1.295x total bet during this round. You can also gamble your winnings after each spin by playing a mini-game where you try to guess the suit or the color of a playing card. Lastly, the wild symbol can expand and fill the entire reel.
