London Tube Slot Features

The primary 5x4 grid sits on the side of a train car, awarding wins for matching at least 3 symbols on neighboring reels, starting from the leftmost one. All 1,024 ways are in play, so there's no need to worry about the symbol's vertical position on the column. Standard payouts award between 0.1 and 1 time the bet for hits on low-value royals, while premium portraits of passengers and a police officer pay from 0.5 to 4 times. As does the traditional Wild for a 5-of-a-kind score, aside from substituting for all regular icons during win evaluation.

Golden Frames

Every time the game logo symbol lands on the grid, it will mark the respective position. All highlighted areas are held during the 10-spin interval, and they will all award one of the following features on the final spin:

• Wild
• Ways Multiplier of 2x, 3x, 5x, 7x, or 10x
• Cash Prize between 1 and 50 times the bet

After the 10th spin, the frames are cleared from the grid, and the cycle repeats.

London Tube Free Spins

Landing 3, 4, or 5 Train Scatters awards 9, 12, or 15 free spins, respectively. The game starts with 3 guaranteed Golden Frames that randomly change positions between spins and award identical features as in the base game. Each Scatter scored during the bonus advances the round along the designated route through stations. Every third station visited grants one of the following bonuses:

• Between 3 and 5 extra spins.
• 1 or 2 additional Golden Frames until the end of the game.
• Win multiplier of x1, x2, or x3 applied to all subsequent wins in the bonus.

Final Thoughts

London Tube brings a humorous, street comic-style theme heavily infused with the British vibe. One could say it almost goes slightly overboard, forcing the Union Jack into every regular symbol. Still, overall, it's a nicely-designed scene that lets you take in the atmosphere of the underground commute. And what creates that environment if not a wide span of characteristic passengers, from a nerdy guy trying to beat his handheld game, a cocky lad with flashy headphones, to an old lady occasionally judging everyone around with her cold look from behind the glasses. Feels like an accurate profile of who you can meet daily in those cars.

On a technical note, the slot utilized a familiar 10-spin system which, in most games, results in Wilds being placed in the highlighted areas. Red Tiger took that functionality half a step further by adding ways multipliers and instant prizes into the mix. An interesting decision, although it often feels annoying when multiple frames appear on the front reels and all you get is the ways multiplier that covers one or two winning positions. And vice versa, when frames drop mainly on the rightmost reels, then Wilds seem to be much more likely, yet unable to connect matching symbols from the front. There are definitely some mixed feelings about such balancing. The bonus does little to improve the situation aside from guaranteeing the 3 frames on every spin with the possibility of getting more. Nevertheless, the same issues persist as in the base game, making it challenging to properly sink one's teeth into the gameplay.
