Io RTP – Be aware of this!

The chances of winning differ significantly depending on the online slot you are spinning on, which is something many players don’t know.

Io, the online slot, is a game that has a moderate winning chance to actually win. This highlights that if you are looking to maximise your likelihood of a win, better slots are available to consider playing!

Measuring the chance of success in a casino game, the usual term is the Return to Player, or what is known as 'RTP.' This points to the average portion of your bet that you'll win back.

A return-to-player of 94% or less is regarded as 'low' when compared to other slots. Slots offering a return-to-player between 94% and 96.5% fall into the 'medium' range, where games in the casino featuring an RTP greater than 96.5% is within the 'high' range.

The return-to-player values might seem almost identical on first impression, but they truly are. Let me offer my overview.

While the return-to-player is often the center of attention, it's really the percent that is withheld by the casino which is the most significant — this is the House Edge.

With Io, you calculate the House Edge by subtracting 96% from 100% = 4%. The House Edge in this particular game is set at 4%. This refers to the amount from every gamble, on the whole, the casino takes for itself.

So, how does this compare when compared to other well-known slots including John Hunter And The Tomb Of The Scarab Queen which boasts an average RTP of 96.5%? The casino’s profit margin for this particular game is set at 3.5%.

Now, we can clearly see the size of the difference by comparing the House Edge in Io of 4% and the House Edge of John Hunter And The Tomb Of The Scarab Queen equal to 3.5%.

How big a difference does the RTP make?

Let's visualize this in an alternative way by examining how many spins you’d get, on average, you’d achieve for each game for a $100 budget.

You make a $100 deposit for the casino account and spin for $1 per play. When playing John Hunter And The Tomb Of The Scarab Queen, you can expect to get around 2857 spins before you run out of money.

This calculation shows $100 divided by 3.5% equals 2857 spins.

In most slot games, the spins take about 3 seconds, meaning that 2857 game rounds translates to roughly 2.5 hours of fun.

Moving on, we’ll now consider a game like Io. On Io, you’ll receive about 2500 spins amounting to around 2 hours of playtime.

Generally speaking, your cash will run out close to 20% more quickly. The likelihood is much lower to land a large payout which is a drawback.

Understanding the RTP of a game is key to boost your chances of coming out ahead when engaging in online casino play. If your motivation is primarily entertainment, it becomes more essential your enjoyment of the gameplay.

How significant RTP is is determined solely by your unique gaming preferences along with your comfort with risk.

For improved chances of success, it’s best to select an option from our curated selection of high RTP casino games instead. If having fun is your priority and you’re a fan of Io, you should absolutely dive into the game!

Io Verdict - What’s Bad About this Slot?

Even though we’ve explored the key points of Io, we haven’t discussed its weaker points.

Here’s the Io Great.com verdict:

• We don’t like that Io does not include a Bonus Buy option. Considering how in-demand this feature is, games missing this feature are less appealing to most players.
  
  

• Since Io caps wins at 5000, it appear less rewarding compared to other slots, leaving many players looking elsewhere for bigger thrills. The thrill of gambling isn’t just about spinning the reels — it’s about chasing the big wins that keep players engaged, and high-paying slots provide that excitement.
  
  

• If you value better odds and lean towards slots with better returns, the RTP of 96% in this game might leave you disappointed. It’s less when compared to modern titles, which means Io delivers less money back to players. The odds of winning is absolutely a significant feature in slot games, and we want it to be elevated to the max.
  
  

Besides the earlier points, it’s crucial to realize that enjoying a slot resembles being immersed in a film. Though it will be a hit for some, and others may feel indifferent, because satisfaction depends on individual taste. How you feel about this game, should be unique to you. As we review based on factual metrics, feel free to explore the Io demo above and see what you think.
