Most Popular Slot Game

Peter and Sons now have over 30 online slots for players to enjoy; many of them with a historical theme or quirky concept. They have even pioneered their own game system called the ‘Step Multiplier’, first seen in their Abrakadabra release.

Listed below are the 5 most popular online slot games created by Peter & Sons:




Return to 1914, as World War I begins in earnest and shakes the world. Behind the enemy walls, Hans Schultz fights for glory.

Named after the leader of the German forces, Kaiser Wilhelm II, Kaiser, developed by Peters & Sons, is a 5-reel, 40-payline slot with a World War I theme. With an astonishing 97% RTP, free spins, and wilds with multipliers, you might be marching to triumph in no time.

While a war theme is usually avoided by developers, Peter & Sons has created a slot with both a unique visual style and a sensitivity to the subject matter. The cartoon style does not feel comedic or cheap, and instead is reminiscent of illustrator Raymond Briggs. Kaiser is a medium to high volatility slot with an incredible RTP of 97%. In terms of maximum wins, the free spins bonus with multipliers caters to wins up to 2,333x the total stake.


Abrakadabra depicts another game adventure with the blue wizard. He is a frequent figure in this game provider's slots, appearing previously in the MonsterBlox Gigablox slot, among others. This time, the blue wizard will be positioned to the left of the reel, fighting against assorted enemies using his powerful magic leading to battles that can result in payouts of up to 10000 times the bet. As with the preceding slots, gamers are in for a visual treat, as Peter & Sons have a fantastic sense of compelling design.

Abrakadabra features five reels, three rows, and 243 chances to win. The game was built with a 96.07% RTP. Abrakadabra offers a high level of volatility. Features include Wild Cascades, Wild Lives, Power Reel, Multiplier Powerup, Step Multiplier, Free Spins, Super Free Spins, Wild Placement, Power Bet, and Bonus Buy (for eligible regions). The Step Multiplier makes its debut in this slot and is an innovative multiplier system unique to Peter & Sons.


Barbarossa DoubleMax

Inspired by the likes of fictional Captain Barbossa, and his real-world historical counterpart; Hayreddin Barbarossa, as opposed to the German code name for the invasion of Russia during WWII, Barbarossa DoubleMax is a piratical adventure from Peter & Sons that sees players sailing the seven seas in search of booty.

Barbarossa DoubleMax is a volatile pirate-themed slot with an RTP of 96.2% that features 5x3 reels and 243 chances to win. In typical Peter & Sons style the visual presentation distinguishes itself from the herd of buccaneer slots thanks to its unique cartoon style and also scintilates the other senses with an excellent soundtrack too.

Barbarossa DoubleMax borrows the popular DoubleMax concept from Yggdrasil, and players familiar with the DoubleMax concept will know what to expect: a multiplier that doubles for each consecutive cascade. The cannonball visuals make it considerably more interesting than usual, and the multiplier can rise higher and higher at random. It never resets throughout the bonus round, allowing for prizes of up to 20,000x the total stake.

Book of Books

There are so many 'Book Of' spots out there that it can be difficult to pick a good one. Enter our hero; Peter & Sons who cut to the chase with their 'Book of Books' slot, which aims to compile all the best bits of the 'Book of' genre.

This game is simple, with five reels and ten paylines, but it has a quirky cartoon style similar to other games the team has created. Book of Books is a volatile, mediaeval 'book mechanic' slot with an RTP of 96.1% and a top prize of 10,000x the total bet. When two book scatters appear, you will be awarded Power-Ups for your next bonus round, which includes extra spins, an expanding win multiplier, and additional expanding symbols chosen at random with each spin.



In Norse mythology, the Valkyries are a troop of maidens chosen by Odin to slaughter those judged worthy. It was only logical that Peter & Sons would create something unique and odd with Norse slots, and thus Valkyries was born. With a tongue-in-cheek cartoon style, if you loaded the game hoping to see gorgeous battle maidens, you will be disappointed, as instead, we have curvaceous opera singers!

Valkyries is a very volatile slot with an RTP of 96.1% and has 5x3 reels with 10 paylines. Two scatters trigger the bottom horizontal Power Reel, which awards Dropping and/or Locking Wilds, both of which come with respins. The Power Reel is active on all Bonus Round spins, which can result in winnings of up to 20,000x the total bet.

Final Thoughts

Despite having been in the game for a relatively short time, Peter & Sons is already leaving an indelible mark on the industry. Standing out from the crowd in such a flooded market is the online slot developers' biggest challenge. Peter & Sons have proven they know how to tackle this task head-on, with their creative visuals seen in games like Kaiser and Book of Books making them instantly recognisable to the developer.

Peter & Sons' slots combine a strong sense of storytelling, visual design,  unique topics, and innovation. Similar developers which come to mind are ELK Studios and Yggdrasil; both of whom have been in the game for over 11 years. The fact that after just 5 years Peter & Sons can vie for its place among these greats just shows the next-level gaming experiences the developer is creating, meaning players should keep a close eye on what is to come from the team, as well as test out some of their existing titles the next time an online slots mood takes hold.
