At Kingmaker you can earn extra multipliers, but unlike "normal" Megaways slots, you earn these multipliers before you win the free spins bonus
In other words, the longer it takes you to win the free spins bonus, the more this bonus potentially becomes worth once you win it.
The slot is set in a beautiful landscape, with a beautiful stately castle in it. That is undoubtedly the domain of the King from the title, although we never get to see the person in question. Or is the castle an indication of what you can do with your money when those bins of gold pour in.

You can win huge amounts with Kingmaker, which can reach over 10,000 x the total bet.
Kingmaker is a 5-reel slot offering 16,807 ways to win and boasts of Big Time Gaming's Megaways mechanism, where the number of symbols on a reel changes with every spin! You can bet from as low as 20 cents and up to €20 per spin; the game has a healthy RTP of 96.65%.
Kingmaker has no king symbol in play, instead presenting pleasingly tranquil visuals, with a majestic castle set in a green lush valley and snow-capped mountains and blue skies in the background.
The symbols consist of lower value playing cards from A to 9 and 4 different colored gems which offer higher rewards and also activate the Gem Multiplier feature. 4 waving flags corresponding to these gems, placed on the left side of the screen and showing the multiplier value starting from 1x, which we will talk more about later.
Winning combinations form left to right with three or more matching symbols. The crown is the scatter symbol and landing 3, 4 or 5 of them wins you 4, 20 or 250 times your stake; the scatter also activates the Free Spins game with 7, 12 or 20 free spins. There is a standard wild symbol.

Gem Multiplier - Feature: This makes up the core of the base game and includes the four gem symbols. You have to land 5 similar gems in all reels, and each time you do so, the four flags will increase by 1x indicating the multipliers. These multipliers are of great value and keep adding until you reach the Free Spins round, after which they reset back to 1x.
Free Spins Game: The Free Spins round is triggered when 3, 4 or 5 Crown Scatter symbols appear on a payline, awarding you with 7, 12 or 20 Free Spins respectively. Your starting win multiplier is now the sum of all four multipliers you've collected using the Gem Multiplier feature! Furthermore, the Gem Multiplier feature is active even in the Free Spins round, and if you land more scatters in the Free Spins game, the Free Spins will be retriggered too!

We really liked this new Megaways offers from Big Time Gaming. The graphics are great, and the gameplay is innovative and the potential for big wins is always there in the free spins game. Only downside may be that it might take a while before you reach the bonus game.
