Kingmaker Megaways (Big Time Gaming) Slot Review

Kingmaker Megaways: Slot Overview 

Kingmaker Megaways by Big Time Gaming is a slot that doesn’t just want you to spin—it wants you to plan. A tactical slow-burn title released into BTG’s vast portfolio of innovation, Kingmaker flips traditional slot expectations on their head by making you work for the bonus, delaying gratification in favor of one of the most rewarding free spins rounds in the Megaways universe. 

Unlike typical Megaways titles that throw cascades, random modifiers, or instant free spins at you, Kingmaker is about progression. Built around the Gem Multiplier system, this 5-reel, high-volatility game invites players to rack up multipliers in the base game that dramatically influence the bonus round. With a RTP of 96.65%, up to 16,807 ways to win, and a maximum win potential of 24,250x, Kingmaker demands patience but promises big things in return.

Design and Graphics 

Visually, Kingmaker Megaways delivers a rich and regal medieval theme. The reels are framed by stone pillars inside a majestic castle chamber, with golden artifacts, fire-lit sconces, and regal banners setting the scene. The background of the base game depicts a tranquil alpine kingdom at the foot of a snow-capped mountain, surrounded by a calm lake and emerald pastures. The symbol set reflects the royal fantasy aesthetic, featuring four high-paying gemstones that match banners on the left side of the screen: green snakes, blue griffins, red minotaurs, and purple dragons. Each gem represents a house, and the multi-colored gem—combining all banners—is the top symbol. Lower-paying symbols are 9 to A playing cards, presented in jewel-toned font to match the game’s luxury tone. 

Kingmaker isn’t packed with fancy animations or distracting effects; instead, it leans into clarity, atmosphere, and refinement—fitting for a game that takes a more methodical approach to gameplay.

Gameplay Mechanics 

Kingmaker Megaways operates on a 5-reel, 2–7 row grid, offering a maximum of 16,807 Megaways, which is lower than the traditional 117,649 of most BTG Megaways titles. However, what it lacks in reel capacity, it makes up for with one of the most unique mechanics in the genre: the Gem Multiplier system. 

Base Game Flow 

During the base game, your primary focus isn’t to hit huge wins—it’s to build multipliers for the free spins round. This is done by landing five-of-a-kind gemstone wins. Each win adds +1 to the respective house banner multiplier, which is displayed beside the reels. 

For example: 

5 green gems → +1 to the green house multiplier 

5 purple dragons → +1 to the purple house multiplier 

These multipliers accumulate over time and carry into the bonus round, setting your free spins session up for massive potential. 

This gives Kingmaker a sense of progression, rarely seen in most slots. You’re not just spinning—you’re building toward a future climax.

Sound and Music 

The audio design in Kingmaker Megaways matches its serene, majestic setting. The soundtrack is a calming orchestral score reminiscent of fantasy films like The Lord of the Rings or The Sound of Music, adding to the game’s epic-yet-tranquil vibe. 

Sound effects are clean and rewarding. When gemstones hit, you hear satisfying chimes; when banners rise with multiplier boosts, triumphant tones announce your growing power. The bonus round swaps the soft ambient music for more tense and triumphant orchestration, raising the stakes appropriately. 

While not flashy, the audio helps immerse players in the medieval-fantasy world and enhances the long-form gameplay strategy.

Bonus Features 

Gem Multiplier Feature 

This is the game’s defining mechanic. Each banner (green, red, blue, purple) begins at x1 and can increase without limit during the base game. The more 5-of-a-kind gemstone wins you land, the more these multipliers grow. 

The twist? These multipliers do not apply during the base game. Instead, they only activate during free spins—but when they do, they apply to every respective gem win. Accumulate x6, x8, x10 multipliers for each house, and suddenly those free spins become explosively valuable. 

Free Spins Feature 

Triggered by landing 3, 4, or 5 crown scatters, this awards 7, 12, or 20 free spins, respectively. Upon activation, you’re taken to a treasure chamber, where the total Gem Multipliers you’ve collected become your starting multipliers for the bonus round. 

The free spins are played on a fully expanded 16,807 Megaways grid, and the action ramps up fast: 

All gem symbols apply their respective multipliers. 

Every 5-of-a-kind gem hit boosts its banner multiplier by +1, even during the bonus. 

Retriggers are possible with 3, 4, or 5 scatters, awarding 7, 12, or 20 more free spins. 

It’s a simple, elegant system that relies heavily on groundwork laid in the base game. The strategy is all about building multipliers before triggering the bonus—ideally when several of them are in double digits.

Betting Options and Payouts 

Kingmaker Megaways supports bets ranging from €0.20 to €20, making it suitable for all types of players. 

RTP: 96.65%, which is highly competitive. 

Max Win: Up to 24,250x your stake. 

Volatility: High—with a grind-heavy base game and potentially explosive free spins. 

Symbol payouts include: 

Purple Dragon: 10x for 5 of a kind 

Other Gems: 3x to 5x for 5 of a kind 

Multi-Gem Symbol: Highest pay potential when matched 

The beauty lies in combining these with your stored multipliers, turning what would be a 5x payout into a 50x or higher win. 

However, it’s worth noting that triggering the bonus too early—before you’ve collected many multipliers—can result in a flat or disappointing session. The game rewards patience, not impulse.

Conclusion 

Kingmaker Megaways is a slot for players who like to build toward something grand. It may not be as instantly gratifying as other BTG hits like Bonanza or Extra Chilli, but for those who enjoy strategy, buildup, and high-stakes payoff, it delivers a truly memorable Megaways experience. 

The Gem Multiplier system adds a refreshing twist to the formula, demanding foresight rather than luck. The free spins round, when entered with strong multipliers, can result in extraordinary rewards. However, getting there requires endurance—this is not a slot for players looking for quick thrills. 

If you enjoy grinding, progressive features, and being in control of your bonus setup, Kingmaker Megaways is a must-try. It’s not for the faint of heart, but when it finally delivers, it can feel like you’ve conquered a kingdom.
