The King of Heroes

One thing we are certain of is that The King of Heroes will be very appealing to RPG fans as well as D&D players, because of its central fantasy theme, which takes you to the world of mages, rogues, and warriors. As far as the design goes the visuals, specifically the background, in The King of Heroes are a hit or miss, depending on your preference.

To some, the simple scenery of a desert may be quite boring, while others may enjoy more minimalistic visuals, that will not distract much from the game. To us, however, the desert background still looks a bit too dry (no pun intended).

What we especially love about The King of Heroes is the epic music that accompanies the gameplay. It honestly sounds like a movie score and does a fantastic job of immersing you in this atmosphere and making you feel like you are on some epic journey.

There are 13 symbols in total in The King of Heroes slot, and these are divided into regular and special. The regular symbols are those from the stack of playing cards, namely 9, 10, J, Q, K, and A. These are considered the lowest paying symbols in the game with the 9 being the one with the lowest value. The symbols that cost more are the rogue in purple, the warrior in blue, the wizard in green, another warrior in red, and the king - the highest-paying regular symbol.

The two special symbols are Scatter and Wild. The Scatter is the white castle and not only is this the highest paying symbol in the game but it will also trigger the free spins feature if you collect a certain amount of Scatters. The Wild is the teal tree and it appears only on real 2, 3, 4, and 5. The Wild will substitute all symbols except the Scatter.

A good-looking slot with multiway mechanics and 6 reels. Sounds Promising!
Well, the game is mostly about hitting free spins, even if those dudes can pay Ok-ish in the base game Be ready for a constant trolling with 2 scatter symbols. Still, sooner or later you’ll land at least 3 of them to get those FS!
FS are big fun d additional free games for scatters and suns symbols. But it really lacks additional multiplier. So empty freebies are pretty common here.
All in all, a decent spinner.

Back in Medieval time all heroes served the King, right? That's the theme of the game, with fine looks and calming music. Potential might seem limited with a max win of 5000x, however, this slot can still surprise you, with it's bonus game, since base game has nothing special to it. Once you get to free spins, slot's potential can be achieved. You get 10 spins, where you need to collect the top symbol, that other premium symbols will change to, once collected enough, giving more spins. Awesome
