Page updated July 2026
Mad Cabs is a taxi-themed video slot from Iron Dog Studio that takes the everyday act of hailing a ride and turns it into a five-reel, 20-payline game with a decidedly cheeky sense of humour. The reels are set on a strangely empty city street at night, populated by taxis, tuk-tuks and limousines rather than pedestrians, backed by an energetic rock soundtrack that ramps up further once free spins kick in.
There's a real personality to Mad Cabs. The setting is quirky rather than glamorous, and the developer has clearly had fun leaning into the "mad" branding, from the punchy soundtrack to the exaggerated vehicle symbols. It won't be to everyone's taste, but it stands out from more generic city-themed slots thanks to that slightly off-kilter presentation.
Mad Cabs runs a default return to player of 95.06%, which is roughly in line with the wider online slot market, sitting just below the 95-96% average band. In real terms, over a large sample of spins the game is designed to return around 95.06 pence in every pound wagered back to players, with the rest forming the house edge. It's worth noting the RTP can shift depending on which bonus buy option, if any, is used.
This is a high-volatility release, meaning payouts tend to be less frequent but can be considerably larger when they land, particularly during the bonus rounds. The reels hold five columns of four symbols each, giving nine regular paying symbols split between lower-value card ranks and higher-value vehicle icons such as the Yellow Taxi, Black Cab and Limo. A wild symbol, styled as a flame, substitutes for all non-special symbols and pays out at the same rate as the top Limo icon when it forms its own combination.
Mad Cabs offers a maximum win of 7,500x the stake, a healthy ceiling for a high-volatility slot of this type, backed by features including the expanding Call a Noober symbol, free spins, and multiple bonus buy options for players who want to skip straight to the action. Stakes are flexible, running from 0.20 up to 50 per spin, which covers everything from cautious low-stake play through to more serious betting.
Mad Cabs is a solidly built, high-volatility slot with a genuinely distinctive theme and a fair RTP for the category. The 7,500x max win, expanding wild symbol and multiple bonus buy routes give it plenty to offer players who enjoy Iron Dog Studio's style. It's well worth trying the free demo at johnessyslots first to get a sense of the pacing before committing real stakes.
