Our take
Iron Dog Studio's Mad Cabs offers 93% RTP with 7,500× max win on a unique 5×4 taxi-themed grid with 20 fixed paylines.
Mad Cabs is structurally unusual. Whilst most 5-reel slots use a 5×3 layout (15 symbols total), Mad Cabs uses 5×4 (20 symbols per spin). This deeper grid increases the symbol density on screen, potentially raising base-game hit frequency compared to shallower grids. The 20 fixed paylines remain modest by modern standards, but the increased reel height compensates somewhat.
The 93% RTP is the lowest in this batch, positioning Mad Cabs as a high-volatility, player-unfavourable game. This reflects Iron Dog's focus on volatility over mathematical generosity—if you pursue Mad Cabs, expect dramatic swings and longer sessions. The 7,500× max win is respectable given the volatility, though the lower RTP means the odds of reaching it are compressed compared to 96%+ games.
The taxi theme is whimsical—neon cabs, city streets, and phone-booth imagery dominate the visuals. Iron Dog's polished design work ensures the theme is cohesive and visually engaging, even if the mechanics are straightforward. There are no cascades, Megaways, or cluster-pays here—just 20 paylines across an unusually tall grid. For players craving mechanical novelty, the 5×4 layout provides that.

FAQ
Why is Mad Cabs a 5×4 grid instead of 5×3?
The 5×4 layout (5 reels, 4 rows) is an unusual choice that increases symbol density on screen. This can raise base-game hit frequency and creates a visually distinctive experience compared to standard 5×3 slots.
What is the expected return over time?
With a 93% RTP, for every €100 wagered, the game returns an average of €93 over a large sample of spins. This is lower than most modern slots and reflects a player-unfavourable volatility profile.
What are the primary bonus features?
Mad Cabs employs traditional bonus features—free spins triggered by scatters, wild symbol substitutions, and multipliers during bonus rounds. There are no modern mechanics like cascades or cluster-pays.
