Gridlock Slot Demo by Grindhouse

Gridlock by Grindhouse Slot Overview

Gridlock by Grindhouse brings a bright, cartoon city-traffic look with teal framing, playful cars, and a comic-book police-station feel. The result is lively and unusual, with a theme that fits the gameplay rather than just decorating it.

Its standout idea is the Call the Count system, where you choose Under, Range, Over or Exact 12 before starting. The game also adds Surge Vehicles, bonus buys, and a high-volatility structure with a 25,000x maximum win. Try the free demo on BonusTiime.

Gridlock Slot Features

Call the Count, Surge Vehicles, News Chopper, Rush Wave, Double Cam, The Parade, and Bonus Buy give Gridlock its identity, mixing player choice, lane-counting tension, and three distinct bonus modes into one traffic-control setup.

Call the Count

Choose Under, Range, Over, or Exact 12 before pressing Count. The final count decides the result, and each call pays its own listed multiplier when it lands. Exact 12 also pays one-off on 11 or 13, which adds a sharper target.

Surge Vehicles

Any counted vehicle can become a Surge Vehicle and carry a multiplier flag. Each one multiplies the Surge Meter, which starts at x1, and a winning call pays its normal value times that meter. The flag sets the figure: a Golden Cab multiplies the meter by x2, a Fire Truck by x3, an Ice-Cream Van by x5, a Parade Float by x10 and a VIP Limo by x25. Up to 6 Surge Vehicles can appear in one count.

News Chopper

The News Chopper can fly over during the count and opens a bonus after the red light. It can start Rush Wave, Double Cam, or, more rarely, The Parade. Your call pays first, then the bonus round begins as an extra layer.

Rush Wave

Rush Wave runs for 6 green lights. It removes the need for a call and pays every crossing vehicle by plate value times the Rush Meter, which starts at x1 and only grows. Surge Vehicles add to the meter, and the meter carries across all 6 lights.

• Sedan: 0.1x plate value.
• CAB: 0.2x plate value.
• Scooter: 0.1x plate value.
• VAN: 0.2x plate value.
• Courier: 0.1x plate value.
• BUS: 0.5x plate value.
• Golden Cab: +1 meter, then 0.5x plate value.
• Fire Truck: +2 meter, then 0.5x plate value.
• Ice-Cream Van: +3 meter, then 0.5x plate value.
• Parade Float: +5 meter, then 1x plate value.
• VIP Limo: +10 meter, then 2x plate value.

Double Cam

Double Cam uses 5 green lights and a split screen with camera A on the left lane and camera B on the right lane. No call is needed. Each red light compares both counts, with Twin, One Apart, and Same Band paying different values against the Double Meter.

• Twin: same count, pays 20x.
• One Apart: one car apart, pays 4x.
• Same Band: both 0-9, both 10-14, or both 15+, pays 1x.
• Golden Cab: +1 meter.
• Fire Truck: +2 meter.
• Ice-Cream Van: +3 meter.
• Parade Float: +5 meter.
• VIP Limo: +10 meter.

The Parade

The Parade closes the street and sends 5 to 8 parade floats through one by one. Each float adds its prize to the Pot, and some floats also carry a banner that multiplies the whole Pot afterwards. The Pot never goes down, so every step matters.

• 2x prize
• 3x prize
• 5x prize
• 8x prize
• 10x prize
• 15x prize
• 20x prize
• 30x prize
• 50x prize
• 100x prize
• x2 banner
• x3 banner
• x5 banner

Bonus Buy

Bonus Buy lets you start a bonus directly instead of waiting for the News Chopper. Each option matches the card price and begins that feature straight away, with no call attached to the bought round.

• Rush Wave: x35 the bet. Starts the 6-light bonus.
• Double Cam: x50 the bet. Starts the split-screen bonus.
• The Parade: x100 the bet. Starts the float bonus.

Gridlock Slot Review

Gridlock uses a bright traffic control theme with a comic-book city layout, teal framing, and a police booth that makes the whole setup feel deliberately playful rather than generic. The real identity comes from the counting lanes, the call buttons, and the way every round turns the street into a moving puzzle.

The Call the Count mechanic gives Gridlock more texture than a standard slot, because the result depends on Under, Range, Over, or Exact 12 before the count resolves. High volatility and the 25,000x ceiling keep the stakes sharp, while Surge Vehicles add extra tension without turning the game into feature clutter.

Gridlock offers independent counting rounds and optional feature buying, with the same theoretical RTP in every mode. The three buys add clear variety, but the overall structure stays count driven rather than expansive. Original is the right word, even when the maths keeps it strict.
