Get set for an altogether shocking time in Seattle, although we’re talking about the electrical kind of shock in this case. It’s all thanks to the 5x3 reels of High Voltage Blackout, an electrifying game from Everi with the potential to deliver up some big cash prizes thanks to an RTP of 95.94%. Match up iconic Seattle landmarks and experience the Respin Bonus, Lightning Multipliers, Stacked Wilds and the exciting Blackout Bonus Game, in which you light up the night sky!
High Voltage Blackout RTP (Payout) & Volatility
High Voltage Blackout reports an RTP of 95.94%, meaning the house has an edge of just slightly over 4% when you spin its reels for cash. This is about average for an online slots game, and it shows that the game returns 95.94 for every 100.00 it takes. Keep in mind that’s an average figure that doesn’t translate into actual winnings per player.
The best indication of whether or not you’re going to derive the maximum amount of fun and entertainment from an online slots game, is its volatility. This is something you really need to know, particularly if you plan on playing the game for real money at an online casino. Play the wrong type of game and you won’t have much fun at all - and you could end up seeing very little for your stake money.
High Voltage Blackout is rated as a medium- to high-volatility online slots game, so it’s quite risky. It’s designed to attract high-stakes players and anyone with a big gaming budget that gives them the leeway to wait for big wins to come along. It doesn’t happen very often, but the sums of money involved make it worth the player’s while.
You can usually tell which are the high-volatility games from their wagering ranges, which tend to be very high in such cases. That’s what the thrill-seekers are on the lookout for, and since wins are usually paid as multiples of your stake, the more you wager, the greater the potential returns!
But you don’t absolutely have to be a high roller, nor do you need to have extra-deep pockets, to enjoy spinning the reels of High Voltage Blackout. Just load it up from our site, and you can play with pretend money, wagering as high as you like with no risk of financial penalties if the wins don’t stack up for you.
How to Play High Voltage Blackout Slots
There are 40 fixed paylines on the reels of High Voltage Blackout, so you only need to decide how much to wager with each spin to get started. Select your coin value from the window to the left of the central Spin button, with options ranging from just 0.01 up to 0.50. But bear in mind that your coin is then multiplied across all paylines, plus a little extra to generate those big cash payouts. You can also apply a Bet Multiplier of up to 15x via the controls to the right of Spin, so your actual wagering options per spin can be anywhere from 0.50 up to a maximum of 375.00.
There’s an Autoplay button, which lets you select 10, 25, 50, 100, 200 or 500 automatic spins at the same bet level. If you want to look at the paytable, you can access it through the menu button at the bottom left corner of your screen. It’s dynamic, so it always shows the actual cash sums you could win at your current wagering level.
How To Win at High Voltage Blackout Slot
Line up three matching symbols across one of the 40 paylines of High Voltage Blackout, and you’ll receive a cash reward. As is often the case with high-volatility slots games, the lower-paying poker card symbols won’t even cover your stake when you spin up three or four examples, so you’ll want to see five of a kind where these symbols appear in a winning combination.
Higher-value symbols are the Seattle Eye, a Metro train, Tacoma Bridge and the top of the Seattle Space Needle, which is the game’s top-paying icon. There’s a Wild, of course, which can help with forming winning combinations since it stands in for every other symbol apart from the Blackout Bonus Scatter. Wilds appear stacked too, filling entire reels and greatly enhancing your chances of a win.

High Voltage Blackout Bonus Features & Free Spins
There are a few bonus features that really raise the gameplay of High Voltage Blackout. The first of these is the Lightning Multipliers, which attach themselves to any of the higher-paying symbols on the reels, increasing their value in winning lines.
There’s also a Respin feature that triggers randomly following any winning spin and guarantees a cash prize.
However, it’s the Blackout Bonus that players will most want to trigger. Three or more Blackout Bonus Scatters transfer the action to the city skyline. Players have five picks out of 28 options, each of which lights up buildings in the cityscape. Each building comes with a cash award, and extra credits are added for filling the entire skyline or for filling entire sections of it.

It’s hard to do, but it’s the way successful slots gamers manage their funds because it works!

High Voltage Blackout Review & Rating
We found High Voltage Blackout to be surprisingly good fun, even though it lacks a Free Spins bonus round. The Bonus Blackout leads to some big cash awards, so we think experienced gamers in particular will want to give this game a try at an online casino. Less experienced players should experiment with the game in demo mode before wagering real money since it’s quite a volatile game.
