Io

Io tells the story of a casino space station, denied landing on Earth, that is pulled by Jupiter’s gravity toward the volcanic moon Io. Try the gravity mechanics of this mineral-rich moon right away with the free demo.

What is Io’s gravity mechanic?

It uses a gravity system where symbols fall down and slide sideways, so more symbols enter the grid. Each win adds one row, expanding up to 8 rows and 262,144 ways. It continues the space station world of ELK Studios slots, so the backstory is interesting too. Setting it on a moon of Jupiter feels fresh as well.

How does the row expansion work?

According to the official description, a row is added with every win. The longer a winning chain runs, the taller the screen grows and the more ways you get. Symbols sliding sideways fill empty spots quickly, so chains are easy to keep going. That makes the chance of one win leading to the next feel higher. See in the demo how fast the ways grow as the screen expands.

How is the Free Drops bonus different?

The Free Drops bonus gives you 7 drops and starts on 8 rows from the beginning. Starting on the widest screen means you can aim for the max ways on every drop. The bonus can also be retriggered. The biggest difference is that you can use the 8 rows from the start, which in the base game you only reach by building up chains. Collecting Charged Wilds and Wild Forge also happens only in this bonus.

What are Charged Wilds and Wild Forge?

During the bonus, Charged Wilds and Wild Forge symbols gather at the bottom of the screen between Free Drops. The official description only covers the fact that they are collected, so it is best to see in the demo how they are actually used. Watch the two symbols pile up at the bottom as the bonus goes on and the flow will become clear quickly.

What should I check first in the demo?

RTP is 96.00%, official volatility is 8 out of 10, and the max win is 5,000x. Hit frequency is 24.6%, with bets from €0.20 to €100. In the demo, watch how often new wins appear as symbols slide sideways, and the mechanics will click quickly. Also keep an eye on the bonus collection elements.
