King Colossus RTP – Be aware of this!
Many players don’t actually realize how big the difference can be when it relates to your likelihood of winning largely influenced by what slot you pick to play.
King Colossus is one of those games where your overall odds of winning drop quite a bit compared to plenty of other slots. When you’re choosing a slot that offers you the strongest odds of winning you’re better off giving King Colossus a miss.
The stat you really want to focus on to make this decision is called return-to-player (RTP). It’s a percentage that shows approximately how much of your total betting amount is expected to come back your way across a long stretch of gameplay. For King Colossus, the RTP is 0%, which lands it squarely in the low-RTP group.
Here’s a quick breakdown of what those RTP ranges mean. If the RTP is under 94%, that’s considered low. RTP in the 94% to 96.50% band is treated as medium. Above 96.50% RTP is what you’d call high.
Initially, a few extra percentage points might not seem like a huge deal. But over a longer stretch of play that gap turns out to be much bigger than it first looks.
Something that’s every bit as important as RTP is the portion that never makes its way back to you — the House Edge. This is calculated by subtracting RTP from 100%. In other words, on King Colossus the House Edge works out as 100% - 0% = 100%. That figure is the share of King Colossus wagers the casino keeps.
Now set that next to a high-RTP title such as Wanted Dead or a Wild, which comes in at 96.50% RTP. For that game, the House Edge is just 3.50%. When you line them up side by side — 100% vs. 3.50% — you really start to see how that difference can add up the longer you stick with playing both of these games.
Even if you still feel like playing King Colossus because you enjoy its bonus features or overall vibe if you were looking at things from a strictly bankroll-optimizing point of view this would be a game to steer clear of.
What Difference Does RTP Make?
To put these numbers into perspective let’s break down how many spins you’d receive for what you’re betting depending on which RTP setting is being used.
If you were to deposit $100 and make $1 wagers every spin. If you’re playing Wanted Dead or a Wild because it has a higher RTP you could see around 2,857 spins before your bankroll hits zero. That’s calculated by dividing $100 by the house edge of 3.50% which equals $100 ÷ 3.50% = 2,857 spins.
Since a typical slot spin is roughly 3 seconds long that spin count would give you about two and a half hours of gameplay before your bankroll is gone.
Now let’s contrast that to a game running a lower RTP for example, King Colossus. Given a house edge of 100%, your $100 bankroll would only last for roughly 100 spins before your funds run dry. which equals roughly approximately (100*3)/3600 hours of playtime.
In practice, this means your money drains far faster — over 50% faster when you’re playing the lower RTP slot. And because you get fewer spins you’re lowering your chances of hitting those major wins before you even hit your first spin.
How important is the RTP of King Colossus? If you're trying to boost your overall chances of winning when gambling online, then the RTP matters more than you might think as a higher RTP directly improves your overall winning chances. But if you’re mainly playing for fun and care less about winning, then gameplay might matter more than the RTP percentage.
Finally, only you get to decide how much RTP matters for your playstyle. It depends heavily on your preferred playstyle and how much risk you’re okay with. Some players aim for the most favorable odds and treat slot games like a way to make consistent gains while others just want an enjoyable experience — even if losses are expected.
If your goal is to make your bankroll last longer and improve your winning odds, you should consider one of the top high‑RTP slots from our list. But if you're having fun with King Colossus and you're playing for pure enjoyment, then it’s perfectly fine to choose based on fun alone.

How Do You Win at King Colossus?
By this stage you’ve gotten familiar with King Colossus and maybe you’ve checked out the free demo version. Yet one major question is still hanging there and it’s this what it actually takes to win at King Colossus?
We’ve already talked about how that RTP is the most important factor when you’re looking at your overall winning chances across pretty much any casino game. When it comes to King Colossus you’re basically dealing with just one RTP version and that means your influence is pretty limited to shift the math in your favor while you play.
One thing you *can* do is use a good casino bonus to provide yourself a small but meaningful edge. But bonuses aren’t always the same so reading the rules carefully is vital.
The first thing you should look at when evaluating a casino bonus is the wagering terms. A lower requirement is definitely better. Preferably you want to find wagering below 30x. If the terms demand over 30x you’re probably wiser to avoid it completely.
Pay attention to bonuses that apply wagering to both deposit and bonus that’s a sign of a bad bonus that essentially doubles the wagering requirement making cashing out extremely difficult. A reasonable bonus typically states terms such as Wager the bonus 30x.
Exercise caution with so-called "no wagering bonuses" because they sometimes hide restrictions. Though they might sound impressive many of these offers stop you from cashing out bonus funds in any circumstance.
They might still be better than having no bonus though the actual value is often much lower than it looks at first.
As a rule of thumb casino promotions often sound better than they turn out to be. And the flashier the offer the more closely you should look at the rules.
In reality even with a solid bonus your odds of losing are still significantly higher than winning. Bonuses can give you extra time to play yet they don’t affect the underlying math.
King Colossus Max Win
When you bet $1 on King Colossus you can win up to $0 meaning the payout tops out at 0x your bet.
Even though the payout is decent it’s definitely not very high compared to the majority of online slots. Many competing slots offer far bigger max win potential and sometimes stretching well into the tens or even hundreds of thousands times your bet.
If the lower max win makes King Colossus feel a bit less exciting and you want games with far higher payout ceilings you might want to check out Africa Gold 2 which offers a 50x max win. or you might consider Zeus vs Hades – Gods of War offering an even bigger 16,000,000x max win.
King Colossus greatt.ink Verdict - What’s Bad About this Slot?
We’ve talked about many aspects that matter when you’re playing King Colossus however we haven’t covered much about the downside of it.
This is our verdict for King Colossus:
We aren’t fans of that this slot doesn’t include the bonus buy mechanic in this particular title. This option is widely loved today therefore any game missing it immediately loses some of its spark.
The max win in King Colossus reaches only 0 and that seems underwhelming to bring the excitement players expect.
We really dislike games featuring low RTP and unfortunately the RTP here is only 0% which isn’t great. This falls below most modern slot RTPs and this leads to King Colossus provides fewer winnings overall in the long run. The payout frequency is extremely important in a slot and we want it to be as high as possible.
