Top 5 slot machines for wagering

Many online casino gamblers take advantage of exclusive welcome offers from Lucky7Bonus casinos. In the vast majority of cases, these offers come with a wagering requirement, i.e. a wager that must be met before you can collect any winnings.

So, before you collect your welcome bonus, or if you've just collected it, Lucky7Bonus offers you a roundup of the most interesting slot machines, as well as a way of finishing your wager as quickly as possible. 

What is a wager? 

A wager is a condition set by the casino when offering a bonus (welcome or otherwise) to players. It indicates a multiplier corresponding to the number of times a given amount must be wagered before any winnings can be withdrawn. For example, on a $100 deposit with a wager x30, the total amount to be wagered before any withdrawal request is $3,000 (100x30). 

However, there are several things to take into consideration when it comes to wagering. It can be calculated on the deposit amount, the bonus amount, or a combination of both. For example, on a deposit of $100 with a 100% bonus (additional $100) and a wager x30, the total amount to be wagered before withdrawal is $6,000 (30 x (100+100)). If the wager only concerns the bonus amount, the offer can be cancelled at any time to allow withdrawal of the deposit amount. 

It's important to read the specific wagering conditions at each online casino that you play at. Terms and conditions frequently vary from one site to another (authorized games and slots, wagering limits, etc.), and your wagers on games and slots don't always count in the same way when calculating wagers. At the vast majority of online casinos, slot machine bets count for 100% (i.e. $1 wagered = $1 counted) in the wager calculation.

Low volatility and high RTP 

To achieve your wager quickly and to withdraw as much money as possible, you need to focus on games that count 100% in the calculation, such as slot machines, and hope that luck is on your side. Players will opt for several strategies:  

  • They will either try to get a balance boost by going to a highly volatile slot machine, with less frequent but more substantial winnings, even if it means quickly losing their money. 

  • Or try to play more cautiously, preferring machines with low volatility and high RTP. 

Low volatility means more frequent but smaller payouts, while high RTP promises the highest possible payout to players. On average, slot machines offer an RTP of between 95 and 98%.  

In this article, Lucky7Bonus suggests that you err on the side of caution and presents its Top 5 best slots for wagering. 

Wild North from Play'n GO 

With a classic format, average volatility, and a decent RTP of almost 95%, Wild North is the perfect slot machine to start your wager on.  

Issued in August 2015 by online game provider Play'n GO, this slot has made this developer a huge success thanks to its theme featuring wild animals in the great cold of the Nordic taiga.  

Its interface comes in a most classic format with 5 reels of 4 symbols each and 40 paylines. 

Thanks to the numerous paylines, spins in the base game offer fairly regular wins, and bonus rounds fall just as easily, allowing players to maintain their balance.  

When 3 Scatter symbols, represented by an aurora borealis, land on the reels, a bonus wheel appears with seven different features offering free spins, cash, WILDs, multipliers, added symbols, or mega symbols.  

It's all here for the amateur player, who can familiarize himself with the world of slot machines while enjoying moderate volatility, with regular small winnings of up to 2,500 times the initial stake. 

Book of 99 from Relax Gaming 

The latest creation from online gaming supplier Relax Gaming, Book of 99, is something of a UFO in the online casino industry.  

Indeed, while the average RTP (rate of redistribution to players) of a slot machine is around 96/97%, Book of 99 offers, as its name suggests, an exceptional rate of return to players of 99%! 

It's this unusually high RTP that makes it a particularly attractive slot to add to your wager. 

Based on the classic Book of machines and the theme of Greek mythology, Book of 99 comes in a 5-reel, 3-row format with just 10 paylines. A WILD counter to the left of the grid provides access to free spins, as does the appearance of 3 book symbols as Scatters.  

As with the other Book of machines, a symbol will be randomly chosen to stretch across its reel to increase the odds of winning. While the volatility of Book of 99 remains high, with a maximum payout of 12,075 times the starting stake, the boosted RTP will attract players who want to finish their wager as quickly as possible. 

Emerald King Rainbow Road from Pragmatic Play 

Since January 2021, this slot machine has been making frequent appearances on slot players' Twitch streams. Despite its dated visuals and haunting music, Emerald King Rainbow Road has won over its audience thanks to its original features.  

Created by studio Reel Kingdom for online gaming provider Pragmatic Play, EKRR revisits the theme of Irish culture.  

Although its volatility is high and its maximum winnings can reach up to 20,000 times the initial stake, EKRR remains an enjoyable machine to play, with interesting features for wagering purposes. 

With an RTP of 96.7%, this slot features a classic 5x3 format with 20 paylines. In the base game, the Cauldron and Mini Machine features allow you to win cash directly, while the bonus game appears as a long multiplier road dotted with cash slots. It's not uncommon to travel this road long enough to multiply your stake significantly. 

Lava Gold from Betsoft 

With very low volatility and a maximum payout of just 120 times the initial stake, this new creation from software provider Betsoft seems perfect for making a wager.  

With Lava Gold, welcome to the time of the dinosaurs, in the heart of a tropical jungle overlooked by a volcano.  

In a 5x5 format, wins are achieved through cluster connections (minimum 5 identical symbols, maximum 25). Paying symbols are removed and replaced by symbols present near empty spaces, until potentially filling the grid with the same symbol. 

On the right-hand side of the grid, a lava counter is used to obtain free spins: it fills up as the various connections are obtained. In the bonus round, a symbol is randomly selected to fill the middle reel.  

Unlike in the base game, the paying symbols are not replaced, but a multiplier is present on each spin, increasing to a maximum of x10 on the 10th and final free spin.  

While the low maximum payout and lack of a retrigger are a shame, a full screen won't be uncommon, making this slot an ideal candidate for wagering. 

Book of Sun by Booongo 

Ancient Egypt theme, classic reel operation, symbol expansion system... Book of Sun is THE traditional slot machine game for you.  

Renowned for its Book of creations, online gaming supplier Booongo has been churning out a series of low-volatility, easy-to-operate slots. 

With its 5x3 format, 10 paylines, 97% RTP, and maximum payout of 5,000 times the starting stake, Book of Sun is the perfect slot machine to end a wager on. 

As with the entire series of ‘Book of’ slots, the free spins bonus round is earned when at least 3 Scatter book symbols land on the reels. A symbol is randomly assigned to expand on its reel each time it appears at least 2 or 3 times on the grid.  

Thanks to the frequency of bonus games and retriggering, Book of Sun remains a classic when it comes to completing your wager.
