Bonus Buy Slots - Online Slots With Buyable Bonus Feature

One of the most demanded functions in online slots in recent years has become **buying a bonus game**. New slot machines are regularly released where you can buy a bonus for a certain amount of game chips. All of them are collected for convenience in this section and allow you to choose the most interesting slot machines for free and play them for “fun money”. Some players use the demo mode to check how expedient it is to bet real money. Slots with feature buy also sometimes require preliminary acquaintance, as the cost of the function is tens, and sometimes hundreds of times more expensive than the main bet.

⭐ Feature Buy Function in Slots

Starting to play a bonus game without waiting for the necessary conditions to fall on the reels remained a dream of slot lovers for a long time. Finally, gambling software developers found a solution to make it a reality. The solution was the **feature buy** function added to slots.

Most gamblers simply call this slot option “bonus buy”.

Whatever the function is called or designated, its purpose is invariable: the player, agreeing to give a part of gambling funds, immediately receives free spins with multipliers, sticky wilds, expanding symbols, etc., or another type of bonus round where the chance to win a big score is much higher than in the main game. 💰💰💰

💲 How Much Does It Cost to Buy a Bonus in a Slot

The cost of such pleasure varies depending on games even from the same provider.  The price of buying a bonus game averages 100 bets.  But it can be 50 xB, 150 xB, and more.

Here, when choosing a slot, one should also take into account its prize capabilities. If they reach several tens of thousands of bets, then for the sake of such a chance, it makes sense to give 100-120 x Bet for a bonus. 🤔

But creators of slots with Feature buy also took into account the voiced belief-trick. The mathematical basis that with each spin the probability of a prize game falling out should increase was laid in slot machines where the cost of purchasing a bonus round decreases from the number of spins made by players.

There are also slot machines where the price of feature buy differs depending on the prize opportunities that will be active during it: higher multiplier for a combination of symbols, more free spins, more frequent wilds, or the number of “sticky” wild reels.

For example, the Hotline 2 slot from NetEnt allows a player who decides to use the bonus round purchase function with free spins the following options:

• 7 free spins with one wild reel for 60 bets;
• 7 free spins with two wild reels for 120 xBet;
• 7 free spins during which the wild symbol will occupy a 3×3 space, i.e., three middle reels. But such a bonus game costs 180 bets per spin.

Real players noted good winning indicators in games from developer Blueprint, but this is not the only provider famous for slots with a large maximum prize. Here, as a confirmation, a list of such slot machines that give chances for a colossal victory mentioning the companies that created them will serve as a clear example. 📝

Below the article are listed slot machines with bonus purchase present in the 4LUCK free games collection, and the number of games with such a feature is already several hundred. Having tried slots with buying a bonus game in demo mode, professional gamblers choose one of the best licensed casinos to test their luck in this game for real money.

Also, for those who want to know which slots with feature buy are most popular among players, we decided to highlight a few of them according to information from several thematic sites.

🏆 Top Slots with Bonus Purchase

Having analyzed top lists of various sites with the best slot machines with an available feature buy function, we decided to select those where there are a lot of other exciting elements and most importantly – high winning potential.

So, the list of the best slots where a player can buy a bonus round with a huge max win:

• 🤠 Dead or Alive 2 – one of the top games in the online gambling sphere from NetEnt. The sequel to Dead or Alive is not only equipped with the ability to immediately proceed to the bonus round with free spins but also has a very high winning potential – over 100,000 x Bet, which is a really significant indicator against the background of other slot machines;

• • 🛡️ 300 Shields Extreme from NextGen – a slot long among the best of the best. In 2019, it gained an additional feature – bonus buy (Buy Pass). Paying 60 bets, the player receives free spins with a multiplier growing to 300, thereby increasing the chances of hitting the slot machine jackpot of 17,773 xB;
  • 🚆 Money Train – the 2019 version of the game from Relax Gaming continues to be popular, although not as before, since the release of the second part of the slot took place in autumn 2020. Nevertheless, it cannot fail to be mentioned in the list, as the first part of Money Train was chosen by both professional players and casino streamers for their broadcasts. This is not surprising. The developers tried to make interesting not only the base game but also the prize round with bonus symbols that increase the multiplier of the main prize during free spins in the Hold and Win style up to 20,000 xBet. And all this potential opens immediately after paying 80 bets;
  • 🚃 Money Train 2 instantly intercepted the popularity of the previous part of the game. For this, the guys from Relax Gaming worked on the design and improved the functionality: firstly – they decided to change the game style to steampunk; secondly – they added more bonus symbols to the prize game; thirdly – they increased the maximum win to x50,000. The price of buying a bonus increased to 100 xB, but this is an insignificant “price increase” compared to the multiplied potential;
  • 🐍 Medusa Megaways – a NextGen slot with the ability to buy a bonus round, equipped with payline change – Megaways, max win x50,000, and a Gamble option allowing to double the prize for a combination by guessing a card;
  • 🔫 Rick and Morty Megaways – a Blueprint slot machine, which, like the previous one, is highly volatile and has a winning potential of x50,000. The slot based on the comedy sci-fi animated series contains three types of bonus free spins with various features, but to use one of them without waiting for scatters to fall, you will need to pay 150 bets;
  • 🦴 1 Million Megaways BC – one of the Iron Dog slots into which the function of purchasing a round with free spins was introduced. Moreover, the player is allowed to choose their number and the cost varies from this – from 50 xB for 6 spins to 270 x Bet for 14. The maximum win in the game is x45,000. But the Megaways function in the bonus also allows collecting over a million combinations on the reels, and in the base game – 117,649 paylines;
  • 🌶️ Extra Chilli Megaways by BTG, which invented the Megaways function, belongs to those slots where the feature buy function is quite cheap. You need to pay 50 bets and a bonus with 8 spins will be activated. Then it is even allowed to risk and double the number of free spins, but a miss will leave with nothing. The maximum victory limit on the Extra Chilli Megaways slot machine is x40,000, which is also a very tempting indicator;
  • ☠️ Deadwood – a slot from developer Nolimit City is somewhat more modest in characteristics – max win here is x14,000, but the game contains two purchase options. One for 71 bets, the other – the most curious – 750 Bet. Someone who risks paying the amount for the second option will immediately receive free spins in which low-value symbols turn into wilds and thus the player has very high chances to hit the jackpot;
  • 🎅 Fat Santa – of course, one cannot do without mentioning this slot machine from Push Gaming, which was among those few slots with bonus purchase several years ago. Although, compared to current max win values, x6,400 does not look particularly impressive, relatively recently it was a quite serious indicator. The bonus costs x80.

An example of a low-volatility slot with bonus purchase can be the game Take the Bank from Betsoft. This is a slot with very low prizes per line, and in total per spin, you can win a maximum of 500 bets. But the Buy feature of the slot machine costs from 27 x Bet, and if the player wants free spins with a large number of wilds, they can choose an option slightly more expensive – up to 55 xB.

🆕 Newest Releases with Feature Buy

Among the “freshest” novelties of the online gambling market, which are also already listed in the 4LUCK demo games section, there are also slot machines with a purchase bonus game. For example, one of them is Iron Bank.

The given list of the best slots with prize round purchase may differ from the preferences of some players, but the presence of a variety of games with this function on the online gambling market will allow finding those that will suit even the most fastidious gourmets of gambling entertainment.

💬 Opinions on the Bonus Game Purchase Function

Some gamblers are skeptical about the function allowing to buy a bonus game and compare it to a lottery. There is some similarity, of course, but bonus games in slots are usually saturated with additional prize opportunities and purchased free spins are much more exciting to watch than the quick result of a lottery ticket with a dry mathematical outcome. 🔢

♟ Strategy in Slots with Bonus Game Purchase

There is a tactic used by players who prefer playing slots with bonus purchase and using this option. It is quite simple and similar to the Martingale strategy. By the same principle, after each bonus that did not pay off, the gambler raises the bet and buys the next one. This tactic is especially used by high rollers who can afford purchases of thousands of game chips.

In slots, the bet amount also grows, but the win can go far beyond 2 to one, and even a more or less “stingy” bonus returns at least part of the bet credits. And if you choose one of the slot machines with high winning potential for applying strategies, then following such a strategy can become quite justified.

But in general, regarding the Feature buy option, it is up to the player to decide: enjoy the process and wait until the bonus pleases them in the base game, or take and buy it immediately, betting that the win will significantly exceed the costs.

The largest selection of slot machines with purchase bonus games continues to be regularly replenished. But not only in new slots allowing to buy a bonus round, but also among other online gambling releases, there is always something interesting. 🎆🎉✨
