Hotline Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 30 paylines

Stakes Range: 15p to £90 per spin

RTP: 96.13%-97.04%

Max Win: 2,800 x stake per spin

The Hotline slot is played on 5 reels, 3 rows, and has 30 fixed paylines. Winning combinations are formed by landing 3 or more matching symbols, beginning from the leftmost reel.

Stakes range from 15p to £90 per spin. The maximum bet used to be set up to £450 but this has since changed. Simply select the coins icon below the reels to change your total bet. Your bet will also double or triple depending on the number of hotlines you choose. More on that in a moment.

The Hotline RTP is 96.13% initially, which is just above average for an online slot. However, the more Hotlines you play with, the higher the potential return (RTP %):

  • 1 Hotline = 96.13% RTP
  • 2 Hotlines = 96.70% RTP
  • 3 Hotlines = 97.04% RTP

The maximum win here is 2,800 x your stake. A screen full of wilds will see you awarded a payout of 400 x your stake on every free spin or respin. As you get 7 of these in the bonus feature, you could win 7 times this amount.

Theme – Audio and Design Features – a retro Miami Vice feel

Theme: Retro

High Value Symbol: Female Character

Compatibility: Mobile, Tablet, Desktop


The Hotline slot game takes you back to the 80s as it draws its inspiration from retro-themed TV shows and popular 80s movies such as Miami Vice. You will see palm trees in the sunset and neon signs in the background as well as 80s music with the soundtrack. It certainly reminds you of old cop movies.

Symbols on the reels include rings, necklaces, and crowns as well as 3 typically 80s characters – a suave sunglasses-wearing gangster, a permed cop with a gun and a class lady with an old school mobile phone. The female character is the most rewarding symbol, giving you 22.22 x your stake for 5 across a payline.

The red sports car is the wild symbol that can appear on any reel. It substitutes for all symbols bar the scatter.

Hotline Mobile


Produced using HTML5 technology, the Hotline slot can be enjoyed on iOS and Android mobile devices. It’s also available on tablet, laptop and PC devices as standard. The 5×3 reel setup works well on whatever device you opt for.

Hotline Bonus Features

There are 3 main bonus features with the Hotline slot game, and each one comes with some exciting elements. The most unique of those is the Hotline Bonus Bet feature, where you can activate up to 3 hotlines, increasing your stake whilst also increasing your chances of potentially big payouts.

Let’s expand on each bonus feature to help you understand the slot fully.

Hotline Bonus Bet feature

Central to the action in the Hotline slot is the Hotline Bonus Bet feature, which you can choose to activate at will. You can play with 1, 2 or 3 Hotlines which affects your total stake.

When you activate 1 Hotline, you will play at 15 coins per level, so 15p to £30 per spin. If you use 2 Hotlines, it will cost you double at 30p to £60 per spin. 3 Hotlines will set you back 45 coins, which is 45p to £90 per spin.

The more Hotlines you activate, the higher your chances to land expanding wilds and re-spins. If a wild symbol lands on an activated Hotline, it will expand to take over the whole reel.

Re-Spins feature


When you land an expanding wild, you will also trigger the Re-Spins feature where you get a free re-spin with expanding wild(s). More re-spins will follow if you land new wilds on the activate Hotline. The expanded wild(s) remain sticky until all re-spins have finished.

Free Spins feature

Look out for the sunset scatter symbol as 3 scatters will trigger the Free Spins feature where you’re rewarded with 7 free spins.

If a wild lands on an activated Hotline, it will expand and remain on the reels until the end of the feature. In theory, you could end up with a screen full of wilds on every free spin, thus landing a potential max win of 2,800 x your stake.

7 is the maximum number of free spins you can get. Although some slots allow for more at times, no retriggers are possible here.

If Free Spins and Re-Spins are won simultaneously, Free Spins are activated first.
