Following the footsteps of the Cygnus slot, the IO slot by Elk Studios is another remarkable science-fiction, fantasy, and space-inspired game that comes packed with 6 reels and up to 262,144 paylines. With the IO slot, Elk Studios once again takes players to an impressive extraterrestrial adventure where players will scoop some fantastical winnings that in the IO slot go all the way up to 5,000 their stake.

What is even more, the IO slot is a rather innovative game release as it features the game developer’s special Gravity gaming mechanics. In other words, the IO slot brings a truly revolutionized way to online slot gaming. The game is also not short on bonus features as it is packed with a couple of rewarding reel modifiers as well as loads of free spins as well as a great Free Drops bonus game during which the IO slot’s gaming grid is expanded to its maximum while all modifiers which triggers are sticky for more winning opportunities.

Hop on the Most Exciting Extraterrestrial Journey

As mentioned at the beginning of this IO slot review, this beautifully crafted superbly designed Elk Studios release is all about fantastical winnings that players enjoy once they hop on this extraterrestrial journey. The game’s betting range starting at 0.20 and going up to 100 credits per spin surely suits everyone’s bankroll.

The IO slot is the developer’s second slot released packed with its Gravity gaming engine while the very first was the Cygnus slot. Since the IO slot uses that innovative gaming mechanics, symbols that are featured on the gaming grid randomly tumble right or left while players. With the very first spin on the IO slot, players are taken to Jupiter or more specifically to one of its many moons. Once here, players will benefit from the game’s Avalanche gaming mechanics which just like in other games of this kind brings loads of consecutive winnings.

Packed with the Gravity gaming mechanics, the game’s symbols gravitate across the gaming grid while winning symbols are always replaced by new symbols that fall either right or left depending on current gravity forces. In terms of its design and visuals, the IO slot is a stunning release. The game’s backdrop depicts a space station with the stunning solar system depicted in the distance.

Symbols that appear across the IO slot’s gaming sessions include the least valuable standard playing cards that gravitate on the gaming grid alongside four-leaf clovers, lucky red sevens, golden stars, and other well-known symbols. The most rewarding symbol here is the lucky red seven which brings payouts of 5x players’ stake for six of a kind winning combos.

Charged Wilds and Wild Winning Multipliers

The IO slot is not only beautifully crafted packed with simple, yet stunning graphics, but it also comes packed with a couple of rewarding bonuses that players will take advantage of as soon as they hop on this journey. There are five bonus features in the IO slot starting with its Avalanche gaming engine which is depicted in several other Elk Studios titles including its Cygnus slot. Besides this one, the IO slot comes packed with Charged Wilds and special Wild Forges.

The game’s Charged Wild symbols have four extra lives. Once these are part of a winning combo, they lose one life while they disappear entirely from the gaming grid as soon as they lose all four lives. These, as expected, replace other symbols on the reels. The IO slot features Wild Forge symbols that once landed on the gaming grid fill those empty reel spaces with awesome wild winning multipliers. Every time these symbols are part of winning combo, their wild winning multiplier value increases. What is even more, Wild Forge symbols become multiplier wild symbols as soon as they reach the bottom of the gaming grid.

Let’s Trigger the Main Bonus Game

The two remaining bonus modes featured in the IO slot are its Laser Bonus and finally its Free Spins bonus. During their gaming sessions here, players are advised to pay attention to the game’s Laser Symbols as when the beams from two laser symbols intersect on the gaming grid, the IO slot’s Laser mode triggers. During this bonus mode, the game’s regular and laser symbols along the laser beams transform into wild symbols.

Here, a single laser also removes itself from the gaming grid as well as all symbols which are located on its laser beam. The fifth bonus mode featured in the IO slot is the game’s Free Spins bonus that requires three bonus scattered symbols landed on the same spin. Once triggered, the Free Spins bonus brings 7 free spins while the gaming grid expands to include 8 rows and the maximum of 262,144 winlines. The bonus mode can be re-triggered by landing three other scattered bonus symbols.

What is even more, during this bonus mode, the game’s Wild Forge and Charged Wild symbols are collected at the gaming grid’s bottom to boost players’ winning potentials. This also means that generous wild winning multiplier symbols will appear on every single free spin of this IO slot’s bonus mode. With a great collection of bonuses, the IO slot’s reel adventure promises fantastical winnings as soon as players head to stunning outer space.
