IO Slot

IO Slot provides players with a front seat view of floating galaxies in space and a chance to win up to 500,000 credits using Elk Studios’ Gravity mechanic. IO slot machine is a voyage through our solar system to Jupiter, and IO is cosmically placed as its moon. Elk Studios, the software developer behind its creation, describes it as a casino space station on a journey to the ends of the solar system. The station holds 24 symbols in each round consisting of six columns and 4096 ways to win. Punters are given regular bet options between 0.20 and 100 credits, and the icon wins to go up to 1,000 credits. Players can reach the jackpot win of 500,000 credits a spin with bonuses like Laser, Wild Forge, Avalanche, Charged Wilds, wilds, and free drops.

IO slot machine pays for three or more matching characters from the first column onward. The game rounds activate for bets between 0.10 and 100 credits. Elk includes its four playing strategies (Jumper, Booster, Optimizer, Leveller) that automate bet changes. When a winning combination hits, IO pays as follows depending on the characters and the number of them that create the cluster:

J	5	10	15	30
Q	5	10	15	30
K	5	10	15	30

Diamond	30	60	120	240
Seven	100	200	400	1,000

IO online slot does not stop at these winnings and awards bonus features to increase them, including;

Avalanche

Whenever IO hits a winning combination, the involved characters vanish from the playtable, and those above gravitate into the left gaps, potentially triggering more combos. Since the columns are not flush, the sinking icons can fall either left or right. Also, after each consecutive avalanche, a row is added to the grid, maxing out at eight. Reaching the highest level unlocks 262,144 ways to win.

Wild and Charged Wild

The IO wild appears as a gold “W” and replaces regular symbols to complete their payout combinations. The game also has Charged Wilds that have four lives. Each time they complete a combo, they spend a life. Once all four lives are used up, they vanish.

Wild Forge

The Wild Forge feature turns an empty icon space into a multiplier wild, and it increases by 1x every time it completes a cluster. Wild Forge becomes a multiplier wild once it hits the grid’s bottom.

Laser

IO pokie machine features laser characters that shoot beams when they appear and destroy regular icons in their path along with themselves. If two laser features intersect, all the icons along the beams become wilds.

Free drops

The bonus moon symbols trigger the free drops feature when three or more appear. The freebies play with eight rows, and the special wilds are collected at the bottom between drops.

Closing Thoughts

IO Slot is much like its predecessor Cygnus with striking visuals and decent payout potential of up to 5,000X the wager. However, the RTP does drop by 0.1% to 96%, but it is not too significant an alteration.
