Mad Cabs Hold and Win Slot RTP, Details & Wager Limits

Every spin in the Mad Cabs Hold and Win slot game starts out on a layout used by most classic online slots—a 5-reel, 3-row setup. There are 10 fixed paylines, and to win, you’ll need matching symbols to land on adjacent reels from left to right, starting with the leftmost.

You can start playing for just 20p, and while that’s a pretty decent entry point, the max bet caps at £50, which is on the lower side compared to what most new slots offer. Just tap the coins icon, then use the plus and minus buttons to set it to whatever fits your budget or feels right for you.

If you’re playing at a non-UK Mad Cabs Hold and Win casino, you’ll have the option to enable autoplay and let it roll anywhere from 5 to 99 spins. Also, as in plenty of the best online slots, you can also switch on Quick Spin to shorten the gap between spins.

Iron Dog Studio has set the Mad Cabs Hold and Win RTP just below average, coming in at 95.15%. If you’re after games with stronger payout percentages, then I’d recommend checking out our list of the highest RTP slots.

The high volatility gives it a bit of bite, as wins are less frequent, but there’s the potential for significantly higher payouts when they do occur. Speaking of, I’d say the Mad Cabs Hold and Win max win of 5,000x is respectable enough, even if it doesn’t top the charts. My best rounds so far have landed around 120x, and knowing it can climb beyond that definitely adds to the suspense.

Mad Cabs Hold and Win Theme—A Reel Tour Of City Rides From Retro Black Cabs To Pink Party Limos

When I loaded the Mad Cabs Hold and Win demo for the first time, I could instantly tell that it was a traditional slot at its core. In fact, there’s literally no distraction in the background, which directs your full attention to the reel activity and keeps the focus exactly where it needs to be.

In my opinion, what turns up the energy and takes the “mad” part of the name seriously is the soundtrack. While it leans heavily into the classic arcade slot feel, it also incorporates a variety of car sounds, including engine revs and screeching tyres, which I thought added a great touch. Besides, it ties into the theme really well and gives the game a bit of a unique edge to be able to stand out from the slot lineup you’ll find at the best UK online casinos.

The lower-paying symbols in Mad Cabs Hold and Win are the classic card royals, each in bold colours and a checkered cab design.

Fun fact: You’ll see this concept used in plenty of other games, too, including several in our lineup of free slots.

Then, payouts pick up as you move through the reel’s vehicle lineup. Mid-range icons include a yellow taxi and a green tuk-tuk, while higher up the paytable are the iconic black cab and the flashy pink limousine.

Here’s the full breakdown of all symbol values:

Mad Cabs Hold and Win Mobile Slot

Mad Cabs Hold and Win plays exceptionally well at mobile casinos, with a layout that feels specifically designed for smaller screens. Everything from bet levels to bonus toggles is right where your thumb expects it.

It loads in under 3 seconds on both Android and iOS, and performance runs steadily the whole way through. Other than that, the visuals retain all of their smoothness and don’t lose shape as you spin.

Mad Cabs Hold and Win Bonus Features

Most of the bonus features in Mad Cabs Hold and Win are ones you’ve probably come across before. However, the way they’re structured brings a few surprises while you’re spinning at the best UK online casinos. Here’s exactly what you’re working with:

Spreading Wilds

In the base game of Mad Cabs Hold and Win, any Wild that lands on the second and third reels has a chance to turn into a Spreading Wild. Its job is to move to the left along its row, converting every symbol it touches into another Wild. Such a chain reaction increases the chance of landing a bigger payout, especially if it spreads across multiple high-paying symbols.

If the Spreading Wild encounters another Wild in its path, it won’t overwrite it. Instead, it boosts the existing Wild’s multiplier. And if the Wild moves over a Bonus symbol, it collects the displayed value and adds it directly to your total win for that spin.

Hold & Win

When the Hold and Win bonus triggers after landing 6+ Bonus symbols, you start with 3 respins, during which only Bonus and Multiplier symbols and blank spaces can appear.

Any Bonus Symbol carries cash values ranging from 0.5x all the way up to 250x your bet. Upon landing, they lock in place on the reels until the round ends or they’re collected.

Note: Bonus Symbols can appear as Special Bonus coins, the Special Collector Symbol, or one of the fixed Hold and Win prizes—Mini (25x), Minor (50x), and Major (250x).

Each time a new Bonus Symbol lands, the respin counter resets to 3. And if no new symbols land during a spin, the number of respins decreases until the feature ends.

You may also land a Special Collector Symbol. This one gathers all visible Bonus Symbol values across the reels, from top to bottom and left to right, before adding them to your win. And if the board already has a Collector Symbol with a Bet Value Multiplier, that can be picked up by later Collectors.

Multiplier Symbols also reset the spin counter to 3 when they land and apply their multiplier to the position they drop into. However, they don’t stick on the reels. Additionally, if a Multiplier lands on a spot that already holds a Multiplier, the values will combine. Meanwhile, if a Bonus Symbol lands on that space, its value will be multiplied accordingly at the end of the round or when collected.

If you manage to fill the entire grid with Bonus Symbols, you’ll unlock the Mega payout worth 5,000x your bet.

Coin Shower

The Coin Shower is a random event that can happen during any base game spin. If triggered, it drops exactly 6 Bonus Symbols onto the reels, instantly starting the Hold and Win feature. It only activates if no other feature is running and at least one Bonus Symbol is already on the screen.

Mad Cabs Hold and Win Verdict: Wild Rides and Fast Spins with a Classic Core

3.4/5
Mad Cabs Hold and Win Slot
The gameplay in Mad Cabs Hold and Win sticks to a rather predictable formula, but with features like Spreading Wilds and a packed Hold and Win bonus, there’s enough here to possibly line up some pretty decent payouts, up to 5,000x.

Mad Cabs Hold and Win takes a simple slot structure and gives it a jolt of energy with fun features. That’s not to mention the vehicle theme, which is refreshingly different, bringing together everything from tuk-tuks to black cabs and party limos.

While the base game maintains a tight and steady pace, it’s the Hold and Win round that marks a significant step up in intensity. Between the Collector Symbols, coin multipliers, and fixed jackpots, the potential is strong when special symbols start chaining together. Also, as Iron Dog Studio’s signature touch, I’m pleased to see the Coin Shower feature included here as well.

If you’re up for something a little different but still on wheels, check out Money Cart 2 by Relax Gaming. It swaps out the flash for full-on Mad Max-style steampunk chaos, set on a 5×5 grid.

Additionally, for rolling more wheels, I recommend playing MegaJackpots Wheel of Fortune On Air by IGT.
