Hotline Slot Game - Play for Fun

The slot Hotline is a Mafia-inspired game from the library of NetEnt. The game is not new, as it was released on March 19, 2018. What sets this 5-reel slot from its contemporaries is the hotline feature, which we will describe in detail later.

The 30-payline Hotline slot allows you to wager a bonus bet, and it has a wild symbol that expands, which means you get more opportunities to make winning lines. Lucky players will also get some big wins with free spins and re-spins.

Main Features of the Hotline Slot

The overall vibe of the Hotline slot machine is akin to popular American Mafia movies set in Miami. The characters and the grid are drawn in 2D, but the symbols are vibrant enough to add flair to its overall design. The game’s sound system is reminiscent of classic rock — something you typically hear in clubs, with police siren wailing in the background from time to time.

Here are the characteristics of the Hotline slot machine online:

  • Software Provider: NetEnt
  • Slot type: video
  • Number of Lines: 3
  • Number of Reels: 5
  • Minimum bet: €0.15
  • Maximum bet: €150
  • RTP return percentage: 96,13% - 97.04%
  • Wild symbol: Yes
  • Scatter symbol: Yes
  • Auto play: Yes
  • Bonus rounds: No
  • Free spins: Yes
  • Jackpot: None
  • Mobile version: Yes

The game has no jackpot, but you can win as much as €2,000 on one spin, and the features described below are the right way to winning.

Hotline Bonus Bet

On the left side of each row, there is a disc. You can click that disc to add 1 more hotline and make a bonus bet. It increases the likelihood of the expanding wild to appear and trigger the re-spin bonus. One hotline is always activated on each round. You can choose which hotline to be active among the three. If you activate two hotlines, your original bet will be doubled. For three active hotlines, your total bet is tripled.

Wild and Expanding Wild

The symbol that represents the wild in the Hotline slot game is the tail of a red sports car. It can appear anywhere, and if it does, it substitutes for other missing symbols. The wild cannot substitute for the scatter. If it lands on a hotline, it expands, forming more winning combos, and awards a re-spin. A good thing to mention about this wild is that it appears in any game mode: in the base game, during a re-spin, and in the free spins round.


The re-spin happens if only you activate the expanding wild. After the wild expands, the slot machine is going to assess your wins. After they have been paid, you will be granted one re-spin. The wild stays on the grid as the other reels re-spin.

Free Spins Feature

You will trigger bonus spins if you manage to land three scatter symbols. This a symbol of a sunset that has the word “scatter on it.” Three scatters will give you seven free spins.

How to Play the Hotline Slot

The Hotline slot online is easy to play, as there are no complications like bet levels or line count to toggle. If you play free Hotline casino slot machine, start by clicking on the coin icon at the bottom of the grid. This will give you a lot of options for betting. In this game, all the 30 lines are active.

Next, spin the reels by clicking on the spin button at the bottom of the grid. If you want, you can stop the reels manually by clicking the spin button once again. You also have the option to activate the auto-play. Just click the button to the left of the spin button.   

The winning mechanics of this slot is the same as of other online slots. You have to land a combination of at least three same symbols. Their positions must be on the specific spots of the paylines. The symbols must also start at the leftmost reel of the grid on adjacent reels.

How Much Can You Win? 

It depends. The prizes of the slot machine change according to the size of your bet. If you wager €150, the biggest prize is €2,000. You can win this if you land a 5-symbol combo of the lady icons. 

Here is a list of the high-value symbols and the biggest prizes they can give when you play Hotline for real money:

  • Lady – €2,000
  • Detective 1 – €1,200
  • Detective 2 – €800
  • Crown – €300

There are also two low-value symbols here. These are the necklace and the ring. Even if you land five of them, you will only win between €200 and €250. 

Upon testing the Hotline demo, we realized that landing a wild is tough. Because of this, the best strategy to use in the game is to activate all the hotlines. However, maintain your bet to a low level. This way, you can spin the reels many times.

What is the right way to win in the Hotline slot machine game is to activate the free spins and wait for the expanding wild to appear. Also, you have to be careful when using the hotlines—they do not double or triple the prizes even if your bets are doubled or tripled. But they, for sure, increase the chances of landing more same symbols on the payline.


The Hotline online casino slot is an innovative game that introduces a new way to win. The hotline is a good addition to the slot features, as it augments the chances of triggering expanding wilds.
