Hotline takes you back into the rebellious 1980s. No, the slot is not about disco music. The game is about the confrontation between law enforcers and organized crime. You'll see a lot of chases, shootings, and robberies. Feel free to be a part of the action and spin the Hotline slot released on 19/03/2018. We recommend reading the slot's review to improve your chances of succeeding.

Hotline RTP and Volatility

9 
The slot's variance is medium, while its RTP varies from 96.13% to 97.04%.
Hotline offers a pretty balanced paytable with only 6 symbols. The highest-pay full line is only 10 times greater than the cheapest one. Of course, the slot's features add some volatility, especially respins with expanding wilds. But, it's not like respins have any other enhancers and modifiers. The game's level of payback depends on the number of activated hotlines. There are 3 different levels – 96.13%, 96.70%, and 97.04%. As you can see, the difference between levels is not that significant.

Theme

8.7 

Hotline was a revolutionary game at the time of its release. The slot's intro is on par with Hollywood movies or Netflix TV Shows. You'll see small episodes with the presentation of the main characters. A movie-like intro is not just some decoration. The thing is that Hotline is basically a slot version of the famous Miami Vice TV Series.

Great graphics do not end with an intro. You'll see fantastic animations during the expansion of Wild symbols and respins. The slot's sounds make the atmosphere even more authentic. You'll hear epic glam rock music and the noises of chasing, police sirens, and radio talk.

The slot has only 8 symbols. The regular ones include a sapphire ring, emerald necklace, ruby crown, and 3 charming criminals – a guy in glasses, a guy with a gun, and a girl in a hat.

Two special elements are the Wild symbol and Scatter. Wild substitutes regular symbols and can expand into the entire reel and activate respins when it lands in the Hotline row. Three and more Scatter symbols award free spins.

About NetEnt

NetEnt is one of the pioneers of online gambling. This Swedish provider is widely considered 1 of the 3 biggest iGaming companies in the market. NetEnt is famous for innovative solutions, exclusive game design, and a solid mathematical team.

The company's roots take us back to the 1960s when it was called Cherry A/B. From the 1960s to the mid-1990s, the supplier had been developing slot machines for land-based clubs. Finally, in 1996 NetEnt entered the online segment and became one of the pioneers of online gambling. It can take hours if we start talking about achievements, awards, and innovations from NetEnt.

The company released numerous epic games. Here are some examples of the provider's all-time hits – Dead or Alive, Starburst, Gonzo's Quest, Divine Fortune, Serengeti Kings, etc. The company also has a significant portfolio of branded titles – from Narcos to Conan.

NetEnt is not only about producing games. The company also offers back-office services, marketing tools, and other B2B and B2C solutions. The price of its acquisition is a good indication of the provider's prowess. In late 2020, Evolution paid more than 2 billion euros to acquire NetEnt.

Bonus Rounds & Free Spins

8 

Hotline Bonus Bet

You can activate from 1 to 3 Hotlines by pressing special buttons on the left side of the board. Each button activates the opposite row on the board.

The number of activated Hotlines influences the overall bet:

  • 1 activated Hotline = Base Bet
  • 2 activated Hotlines = 2x Base Bet
  • 3 activated Hotlines = 3x Base Bet

When the Wild symbol lands on the active Hotline, it expands to cover the entire reel and trigger re-spins.

Expanding Wilds and Respins

If you catch Wild Symbol on the active Hotline, both Expanding feature and Respins will be activated. The Wild symbol will expand to cover the entire reel, and respins will be taken with the expanded reel. Catching another Wild symbol during respins reactivates the feature. All landed Wilds will stay on the board until the end of the feature.

Respins end when you either fill the entire board with Expanding Wilds or do not land a new Wild symbol.

Hotline slot Respins

Free Spins

Catch 3 Scatter symbols on reels 1, 3, and 5 to trigger 7 free spins. During free spins, every caught Wild element expands and stays on the board until the end of the round.

Hotline Demo Play

Are you still not sure if Hotline is a good fit for you? Try spinning the slot's demo version without the risk of losing money. It's an excellent opportunity to learn the game and its features closely. During the free play, you'll be betting with virtual non-withdrawable funds. Even if you lose this money, you can get a new deposit by restarting the slot.

Hopefully, demo play will help you to get answers to all remaining questions regarding the slot.

Max Win

6 
The maximum win in the Hotline is 400x the bet.
The maximum odds of x400 don't sound impressive. Moreover, you can reach the max win under the condition of filling the entire board with the highest-pay symbol. But you can always count on expanding wilds and re-spins. Getting 3 Wild reels on the board guarantees big wins. Free Spins are even more attractive regarding big wins, as Wild reels stay on the board until the end of the round.

Overall Rating

7.9
Hotline is a highly entertaining slot with fantastic graphics. It's one of the signature games in the NetEnt portfolio. And you can clearly see why. The slot is very appealing and eye-catching. And even low payouts cannot outweigh good things.
