The IO slot machine from ELK Studios takes you to an intergalactic space station with a beautiful view of space. IO was launched in June 2020 and has gradually grown to become one of the most popular games from ELK in the UK and Germany. So this is definitely an exciting game to test out for most players around the world if you like a game with lots of variety and bonus features that help you win.

So what is it that makes IO so popular?

One of the most important features of the game is the expanding game board. There are no reels here, and all the symbols fall into place for each spin. As the reels expand, so for you next 4 times more pay lines, and also the reels can be expanded a full 4 times. This means that you can get up to 262,144 pay lines active during every single spin!

IO Symbols

You have 8 main symbols on the IO slot machine that can give up to 10x the bet if you land the symbol with the highest value. this symbol is then the familiar 7th number we recognize from most slot machines. Here is the payout table for IO in the main game:

  • 7- Provides up to 10 x bet with 6 of a kind in a payline
  • Diamond- Provides up to 2.4 x bet with 6 of a kind in a payline
  • Clover- Provides up to 1.2 x bet with 6 of a kind in a payline
  • Star- Provides up to 0.9 x bet with 6 equals in a payline
  • Ace- Provides up to 0.3 x bet with 6 of a kind in a payline
  • K- Provides up to 0.3 x bet with 6 of a kind in a payline
  • Q- Provides up to 0.3 x bet with 6 of a kind in a payline
  • J- Provides up to 0.3 x bet with 6 of a kind in a payline

As you can probably see, there is a big difference in the payouts from the best-paid symbol and the others. But in this game, as I said, you have almost infinite potential for pay lines in the game, and therefore also provide greater opportunities to hit small wins during the game.

Game Setup on IO

The slot machine starts with a 6 x 6 game layout where the symbols crash down on the reels from above. The object of the game is to get at least 3 identical symbols in one of the paylines to be paid out. Also, all paylines pay, so you can get multiple wins on one and the same spin.

The slot machine can be expanded to an 8 x 8 layout, and then you have an insane number of paylines in the game.

  • 6x6 = 4096 paylines
  • 7x7 = 15,625 paylines
  • 8x8 = 46,656 paylines
  • 9x9 = 117,649 paylines
  • 10x10 = 262 144 paylines

On the slot machine, you have 12 different bets to choose from €2 to 100 per spin. These are just a few options to adjust the bet along the way, so this is not a game for those who like progressive play. But in return, this is adapted to most players' budgets.

Bonus features on IO

  • Re-Spin IO gives you lots of opportunities for free spins. Each time you hit a win, you get another chance to land a win on the next slide. This happens until Fri until you do not win on the last landslide.
  • Wild The slot machine also has a wild symbol that can further help you win while playing. This replaces all other symbols in a payline. Also, you may also encounter a "Charged Wild" that applies in 4 spins.
  • Multiplier The Wild symbol can also have a multiplier that increases for each landslide you win. This starts at 1x and increases progressively all the way until you get a spin with a loss.
  • Laser If there are many spins without winning, the game will help you trigger wild symbols with two lasers that change random symbols on the wheel to wild.
  • Win Potential IO is a slot machine with great winning potential. It has a high RTP and up to 5000x stake in top payouts that can land on any spin. In pure money, this means up to 5 million kroner to collect on this slot machine with the highest bet.

Conclusion of IO

ELK Studio has made lots of exciting slot machines at the moment with the expanded rows of the game. Cygnus is very similar in the layout if you prefer a different theme on the slot machine, but IO will probably capture most people with great graphics and a nice layout.

The biggest advantage of these slot machines is probably the re-spin function, where you can get almost endless free spins if you get the reels extended to max. In addition, you have great multipliers that help you get more out of your winnings.
