Peter and Sons casino software is undoubtedly one of the most innovative iGaming casino developers currently on the market and their online products are always eagerly awaited in the punters' community.

This time, we’re looking at Kaiser - an online video slot inspired by World War I played on 5 reels, 5 rows, with 40 fixed paylines. As far as available bonus features are concerned, you can expect Wilds, multipliers, scatters, and retriggerable Free Spins. 

It’s a med-highly volatile online game with an RTP of 97%. Also, the maximum available win sits at 2333x the bet. 

Before we jump into the further details, it should be noted that, thanks to the HTML5 technology, you’ll be able to spin it even on your mobile devices. 

Theme and Symbols 

Although roughly translated as emperor, Kaiser was a colloquial name for soldiers of the German or Austro-Hungarian Empire during the First World War. As expected, the main story takes place in a trench while the list of low-paying symbols consists of standard royal card letters. 

Different kinds of food used during the War, medics, Rotes Kreuz (Red Cross) caravans are the premium symbols here. 

Also, all punters who decide to give this online one-armed bandit a spin can count on Wilds and scatters. 

Betting Options and Other Functions

As already stated above, Kaiser uses a 5x5 grid with 40 fixed paylines meaning that you won’t be able to change the number of lines in a play. To form a winning combination, you’ll need to land at least 3 identical icons across a single line. 

The theoretical return to player (RTP) is set at 97% which is far above the current standard, while the med-high variance is paired with the top payout of 2333x the bet. 

Special Features

Wilds will replace all other regular icons (except scatters) and help you form more winning combinations. During the base game, up to 10 Wilds will be randomly placed on the reels and they’ll increase the overall multiplier up to x3.

By landing 3 scatters on reels 2, 3, and 4, you’ll trigger the Free Spins bonus feature and the game will award 7 freebies. In addition to so-called roaming Wilds, the feature also benefits from an increasing multiplier, but this time it can go as high as x5. 


World War I has changed the world radically and it seems that Kaiser has the potential to change the iGaming industry. Win up to 2333x the bet via Wilds, scatters, increasing multipliers, and Free Spins and enjoy all benefits of an above-average RTP.
