Book of Dead
The game that started the adventures of Rich Wilde, a fearless Indiana Jones-like handsome devil, came out in 2016. It was created by Play’n GO and popularised the genre forever. The highly volatile slot provides substantial wins that do not come too often. With an RTP of 96.21%, the game slightly exceeds the industry standard.
You can start playing with only £0.1, while the highest bet is £50, meaning the game is tailored to every budget. The Free Spins round with the titular book activated brings the Expanding Symbol mechanic, carrying hefty wins. However, there are more features that can bring you exciting payouts and great rewards over time.
If Expanding Symbols cover all the reels, you will receive the maximum payout of 5,000x the stake, which means you can hope for £250,000. Moreover, after every regular win, you can activate the Gamble feature and potentially double or quadruple your winning amounts. The excitement never stops while playing the slot that changed the entire iGaming industry.
Book of Ra Deluxe
The original Book of Ra slot was the first ever such game, released in 2005. Four years later, this sequel came from Novomatic, and the fans adored it for a reason. Although it has a lower RTP of 95.10%, it offers fast-paced gameplay with plenty of thrills and the possibility of big wins. The volatility is high, and the tempo never slows down, promising interesting rounds.
The lowest bet amounts to £0.1, and the highest wager is £400, providing the possibility for hefty wins, especially on stronger bets. The book simultaneously represents a Wild and a Scatter, and the features are pretty standard for such a slot. It has the Expanding Symbol during the Free Spins round, which can grant handsome payouts.
The Gamble feature spices up the game, and the maximum win of 5,000x the bet sounds great. Moreover, the hit rate is 30%, which means every third or fourth spin, on average, should be a winning one. Of course, it is a challenge to grab big wins, but Book of Ra Deluxe is worth playing. It is one of the best titles of all time in this genre.

Book of 99
Relax Gaming did a fantastic job with Book of 99 by equipping it with enough similarities to the rest but adding some different elements to keep it fresh. It has the usual high variance, with a tempo that barely leaves you any time to think. The phenomenal RTP value of 99% is out of this world, and any slot enthusiast should give this game a shot.
Although the central Expanding Symbol feature is the same, Relax Gaming inserts enough novelty into the gameplay to make it attractive. A Wild collection is an exciting element; filling the meter with 99 Wilds grants 10 free spins. Expanding Symbols do not have to be next to each other to pay. The betting scope ranges from £0.1 to £100.
With a hit rate of 29.83% and the maximum win of 12,075x the stake, Book of 99 gives players plenty to hope for. The epic RTP value and additional free spins collection system are extraordinary and make the game immensely appealing. The road to big wins is difficult, but it is worth hitting. “Book of “slots are a dime a dozen, but some are better than others.
Legacy of Dead
Legacy of Dead is another entry from Play’n GO, but it does not have a massive following like Book of Dead. However, it is an excellent game with multiple familiar elements contributing to phenomenal gameplay. The highly volatile slot has an RTP of 96.58%, and the burial chamber symbol is the most interesting in the paytable.
You can get the ball rolling with only £0.1; the highest bet is £100. The burial chamber symbol is a Wild and a Scatter, and if you land 5, it pays out 500x the stake. The re-triggerable Free Spins round is where a randomly chosen Expanding Symbol appears. As usual, it pays wherever it lands, bringing the maximum win if the grid is full.
However, there is a new ingredient in this game. The row of symbols lies above the reels, and the special symbols are in colour. Whenever the Free Spins round is retriggered, another special icon is added, and the process can repeat. The aim is to make all 9 symbols special and expandable. The maximum win is 5,000x, allowing players to fight for £500,000.
