Bonus games are undoubtedly the main thrill of slot machines. Players are willing to press the spin button for hours, anticipating the bonus game. They know that the multiplier may break their personal and, possibly, even the world record. Fortunately, there are more and more bonus buy slots where you can trigger a bonus game immediately for a fixed amount. Of special interest are Megaways slots that also include a bonus buy option.
There are different opinions about buying bonus games. Some people believe that paid bonuses most often do not pay off and bring a negligible multiplier. Nevertheless, the experience of many players suggests that such bonuses can pay huge and are in no way inferior to bonuses won in the main game mode. When playing with crypto, you can also buy bonuses, thus reducing the waiting time and immediately moving on to the most exciting part. We have assembled a list of top games where you can buy a bonus game with Bitcoin or another cryptocurrency.
Mental by NoLimit City
Mental is an online video slot by NoLimit City released in late summer 2021. The slot has 108 paylines that can be increased, while the maximum payout per spin can reach x66,666 of the bet.
There are three bonus game modes in Mental. You can win all of them in the main game mode or buy. The Autopsy bonus game is worth x80 of the bet, the Lobotomy bonus game is x200, and the Mental bonus game is x1000.
It may seem that the Mental bonus is unreasonably expensive. Indeed, to play the bonus game with a $1 bet, you must pay $1,000. But this bonus enables an opportunity to win the maximum multiplier, which is x66,666 of the bet. In the abovementioned scenario, that would be $66,666, which is a good amount considering the massive potential of the slot.
Nevertheless, there have already been cases when players won the maximum multiplier in cheaper bonus games, so it always makes sense to try different bonuses, changing the bet as needed.
Punk Rocker by NoLimit City
Punk Rocker is an online video slot developed by NoLimit City and released in January 2020. This game started the trend of slot machines with various bonus game purchase options. Typically, the most expensive option is the most volatile one, but at the same time it can bring cosmic wins.
There are 2 purchase options to choose from: x80 of the bet and x238. The player gets 8 spins in both variants, but they differ in the number of floating Wild symbols — 3 or 4, respectively. It’s up to you whether to buy a more expensive or a cheaper bonus. Keep in mind, though, that during the bonus game, Wild symbols trigger additional features, and they are of great importance for the final result. Perhaps, to understand the difference in potential, it is worth trying both bonus game variants.
Mongol Treasures by Endorphina
Mongol Treasures is an online video slot by Endorphina. The slot has 10 paylines, while the maximum payout per spin can reach x5,000 of the bet.
The bonus game starts when Wild symbols appear on reels 3, 4, and 5. In the beginning, a random symbol is selected as an expanding one. Payouts for such symbols are awarded regardless of whether they appear on consecutive reels or not.
There are 8 options for buying a bonus game in Mongol Treasures that differ in an expanding symbol. The bonus game with 10 as an expanding symbol costs x76 of the bet, while the bonus game with the Mongol symbol — x133 of the bet. The bonus result directly depends on how often the expanding symbols appear, so it is worth experimenting with different bonuses, changing the bet size accordingly.
Deadwood by NoLimit City
Deadwood is an online video slot developed by NoLimit City and released in April 2020. The slot has 576 paylines, while the maximum payout per spin can reach x13,950 of the bet.
In the main game mode, the bonus game starts when Scatter symbols appear on reels 2, 3, and 4. In addition to Scatters, Badge symbols can appear on reels 1 and 5. Then, the player gets a bonus game with a potentially significant win. Bonus games cost x71 and x750, respectively.
Moreover, there is a choice between the Hunter Spins and Gunslinger Spins. While selecting, the player is warned that Gunslinger Spins have increased volatility. This is true, since the wins in Gunslinger Spins can be close to zero but in the same time can easily reach the maximum multiplier. Such results are harder to achieve in Hunter Spins.
San Quentin xWays by NoLimit City
San Quentin xWays is an online video slot developed by NoLimit City and released in 2021. The count of paylines in this game starts with 243, while the maximum payout per spin can reach x150,000 of the bet.
The maximum payout per spin immediately attracted our attention, as it surpasses the values of all other games from NoLimit City and most slots in general. To get such a payout, you most likely will have to buy the most expensive bonus game, which costs a lot — x2000 of the bet. In the main game mode, you need to catch five Bonus symbols to trigger the same bonus game, which is almost impossible to do. There are also purchase options for x100 and x400 of the bet.
The game provider has added extra features for maximum payouts: a mysterious symbol with multiplied wins and Jumping Wilds that can be upgraded to a multiplier of x512. Moreover, the Bonus symbols during the bonus game unlock the closed positions, award extra spins, and turn into the Jumping Wilds.
Minotaurus by Endorphina
Minotaurus is an online video slot by Endorphina. The slot has 10 paylines, while the maximum payout per spin can exceed x4,000 of the bet.
The bonus game in Minotaurus starts when the Minotaur wild appears on reels 2, 3, or 4. The Minotaur jumps on the reel, increasing the multiplier by 1 point with each respin. A big payout is guaranteed if the Minotaur jumps 20-30 times and the top symbol complements the winning combination.
There are three bonus games available for purchase. Minotaur on reel 2 costs x25, on reel 3 — x36, and on reel 4 — x202. It should be noted, that the potential of bonuses is proportional to their value, so the third option is the most promising one.
East Coast vs West Coast by NoLimit City
East Coast vs West Coast is an online video slot developed by NoLimit City and released in 2021. The slot has 243 to 84375 paylines, while the maximum payout per spin can reach x30,000 of the bet.

Like other NoLimit City games, East Coast vs West Coast has many additional features, namely xWays, xNudge Wilds, Multipliers, and Linked Reels. In the expensive version of the bonus game, two additional features are guaranteed for each spin — just what you need for the maximum multipliers.
