The London Tube slot was originally released in 2023 by developer Red Tiger and features British themes throughout. It’s clear that the developers have drawn inspiration for the world’s oldest underground railway system for the visuals in this release, even naming it after the London Tube, and featuring similar imagery to what is seen in the London Tube itself. There are also some commonly seen bonus features in this slot, like free spins and some other features we will talk about later on.
London tube game background
As we said, the London Tube slot was developed by Red Tiger and entered the online casino industry in 2023. And compared to some, Red Tiger is quite experienced, having released over 200 slot games, which is a significant number compared to some developers. The playgrid in the London Tube slot features a black backdrop behind the symbols, so they stand out, and a dark silver lining around the frame, which also splits up the symbols. Certain symbols take up more space than others because of their larger backgrounds.
The playgrid in the London Tube features a white and blue brick structure, which has been standing for a long time. The main feature in the London Tube slot background is the trains that rush in, sparks from the metal rail lines light up the scene on arrival, and the train also matches the colour scheme, with white and blue, but also features red, which could link back to the British theme. Behind the trains, there is a banner displaying the ‘next train’, and on the left of this, the London Tube logo stands clear in a spray-painted style, which links back to the underground theme.
The London Tube game does a great job of displaying the British underground theme throughout the gameplay design, found in games comparable to this slot. The overall design uses animated visuals during gameplay, set in an underground station with British themes and stereotypical elements seen in an underground station.
London tube slot symbols
The London Tube slot features a diverse range of base-game symbols on the reels, each with its own imagery and values. The lower valued symbols in this release are depicted by classic playing card imagery seen in classic card games like Blackjack and Poker. And all these cards have a Union Jack style, which links back to the British theme. The higher valued symbols in the London Tube are depicted by a range of detailed characters, each set on a uniquely highlighted Union Jack flag background.

Alongside all the base game symbols in the London Tube slot, there are also some bonus symbols. There are wild and scatter symbols, which are a common feature in many online slots nowadays, with them both being very important in the game to potentially trigger unique bonus features. The wild symbol is depicted as a newspaper, and the scatter is shown as a train symbol.
London tube bonus features
Red Tiger has used a selection of bonus features in the London Tube slot that players can randomly encounter. As mentioned, this game features a Wild symbol, which can substitute for all base play symbols to create or extend matching combinations across a payline.
In the base gameplay of the London Tube slot, Tube symbols can appear on each spin except for the tenth base spin, and if landed, it will leave a golden frame in that particular position. These frames left behind will remain sticky until the tenth spin, and if more than one Tube symbol is landed on the same position, the frame will duplicate to a random position. On every 10th spin with frames left behind, the Train Arrival bonus will be activated, which can randomly trigger one of three bonus features, including: the Wild feature, Ways Multiplier bonus, or the Cash prize feature.
In the Wilds feature, all frames will be turned into Wild symbols, which will operate in their regular way with the ability to substitute for base play symbols. The Ways Multiplier bonus can apply multipliers at random to every position with a frame present, which can range from 2x to 10x. The cash prize feature in the London Tube slot displays monetary values on positions with frames, ranging from 1x to 50x the total bet stake. The Free Spins feature in the London Tube slot can be triggered if players land 3 or more Scatter symbols on the reels in the same spin.
Each triggering Scatter symbol in the London Tube slot will award 3 Free Spins, with a minimum of 9 and a maximum of 15 for the bonus rounds. The bonus will begin with 3 active golden frames, which land on random positions on all free spins, and award one of three features during the Free Spins feature. Scatter symbols can land on the reels, and each time they do, the train moves one position further along a progression meter. The train’s progression is shown above the reels, with each third station marked with a ‘Bonus’, which has the potential to award either additional free spins, additional golden frames, or multipliers.
