Hotline online slot game review
Hotline puts the gameplay in your hands as you enter 1980s Miami. Raising the stake with ‘Hot Lines’ can improve your chance of landing re-spins and wild reels, which become especially valuable when they stick to the reels during free spins.
Theme and storyline
Travel back to the 80s, near the end of Pablo Escobar’s reign over Miami. The scene is filled with pink and blue neon signs, a skyline of skyscrapers, palm trees, fast cars, valuable jewels, guns and wealthy women as you spin for a share of Miami’s riches.
Graphics, sound and animations
Although Hotline has a retro 80s look, it is presented as a modern 3D slot for mobile and desktop play. The reels are compact and colourful without an overload of animated effects. Animation appears when the free spins feature opens through its intro screen, and on the reels when a Hotline feature is enabled, launching a film-like scene of cars racing through Miami.
The soundtrack has the feel of a Miami love song, with music in the style of a Miami Vice film. Beneath the theme tune, police sirens and radio chatter reinforce the distinctly Miami atmosphere.

Top Casinos to Play Hotline:
Gameplay
The game uses 6 regular paying symbols across 5 reels, 30 pay lines and a 5x3 grid. The 6 symbols show a wealthy woman on the phone, a gunman in a blue suit, a sunglasses-wearing man in a beige suit, a silver crown jewel with pink accents, a silver necklace jewel in green and a blue bracelet jewel with blue emeralds. Matching 5, 4 or 3 symbols on a pay line pays between 500 coins and 5 coins multiplied by the ‘Bet Level’.
The paytable displays symbol payouts in coins, while the selected level determines your total coin stake. Every level puts 15 coins into the spin bet. The ‘BET’ area shows the total coins wagered, with their cash value underneath. ‘Coin Value’ sets the cash value of each coin. Choosing ‘Max Bet’ automatically sets the spin to ‘Level 10’ but does not alter the ‘Coin Value’.
The coin total for each spin rises when you activate the ‘Hot Lines’ beside the reels. 1 hotline remains active by default; the next section explains how this affects the bet.

Bonuses and free spins
Hot Lines: Hot Lines sit to the left of the reels, with 1 active by default. Each added Hot Line increases the spin bet by the figure shown in the ‘BET’ box. For instance, a 30-coin spin bet becomes 60 coins when another Hot Line is added; adding another then raises it by 30 coins to 90 coins per spin.
Expanding Wild: The wild is the rear of a red sports car. It substitutes for any of the 6 regular symbols when it lands on the reels. If it lands on an active ‘Hot Line’, the car burns rubber and awards a re-spin after expanding to cover the entire reel.
Free Spins: Land 3 sunset scatter symbols on reels 1, 3 and 5 to receive 7 free spins. If the wild lands on a ‘Hot Reel’ during the free spins bonus, it expands and stays on the reels until the round finishes.
Bet sizes, RTP and variance
You can play from ‘Level 1’ through ‘Level 10’, with 15, 30 or 45 coins per level when 1, 2 or 3 ‘Hot Reels’ are active respectively. Each coin can be set from 0.01 to 1.00. With 1 ‘Hot Reel’, the min-max bet is 0.15-150.00 per spin; with 2 ‘Hot Reels’, it is 30.00-300.00 per spin, and with 3 ‘Hot Reels’, it is 45.00-450.00 per spin. The slot is listed as medium variance, although that can depend on the number of ‘Hot Lines’ selected. The stated 96.13% return is an expectation rather than a guarantee, and the same qualification applies as the number of ‘Hot Lines’ changes.
Conclusion
Hotline is described as increasingly expensive once you add more ‘Hot Lines’. It identifies 2 ‘Hot Lines’ as the apparent optimum, reporting that expanding wilds can appear reasonably often in the base game. Since free spins are also described as frequent, the review says 2 ‘Hot Lines’ may leave 2 or 3 wild reels by the end of the free spins session.
