You will find that Extra 100X slot features 3 reels and just 1 payline – this is standard for classic slot machines. But, you don’t have to match 3 of a kind to win – you don’t even have to match 2 of a kind to win, because there are payouts offered for matching just one symbol.
The design of the slot is pleasant and it resembles a one-arm bandit. When playing, your machine is positioned centrally, but there are other slot machines on the screen – this gives you the feeling that you are inside a casino playing a real slot game.
You don’t have to pull the arm to spin the reels, you click the buttons that are situated on the screen. You can view the total amount that you can win to the top of the reels and your balance, total bet and prize to the lower of the screen. Above the fourth reel is a display panel – this will show how much you have won when you have played the Extra 100X bonus reel.
Symbols that make up this game are; Extra 100X, red 7s, purple 7s with single bars, a mix of purple and red 7’s, triple bars, double bars, single bars and cherries.
Extra 100X slot machine offers a 100x your stake non-progressive jackpot, which turns into a lucrative 20,000 for players who are betting maximum stakes. You will be awarded this sum by spinning in three of a kind of the Extra 100x symbols.
The second highest paying symbol on the reels are the red 7 symbols, which will award 40x your stake.
As previously stated, you don’t just need three of a kind to win; by spinning in a combination of any bar will award a 5x multiplier, any two symbols with a cherry on the 3rd reel awards a 3x multiplier and any one cherry awards a 2x multiplier.
With Extra 100X slot machine being a classic slot game, you won’t find many features hiding on the reels, but what it does offer is:
Extra 100X slot game has a return to player (RTP) percentage of 93.96%. We love the sounds that accompany this slot game, especially when you don’t spin the reels; there will be a heart-thumping tune with a message stating “You can’t win unless you spin.”
Due of the limited features with this slot, you will have long periods of playing without triggering a win, which is why it is a low variance slot machine.
When we played Extra 100x, we only managed to trigger small wins every now and again, which boosted our balance slightly to keep us playing a little bit longer. There is a big jackpot on offer, but payouts are few and far between in this high volatility online slot machine.
