There are 1,024 ways to win on the five reels of the London Tube slot machine. When matching symbols show up anywhere on neighbouring reels from left to right, starting with the leftmost reel, wins are awarded.
Lower-paying symbols on the reels are represented by the A–10 Royals with the British flag in the corner of each symbol. The more expensive ones have figures you could see on the Tube: a child using his phone, a fashionable woman wearing headphones, an elderly woman reading a book, a man wearing headphones, and a police officer. The most profitable symbol is the policeman, which pays off 1, 2, or 4 times your entire stake for combinations of 3, 4, or 5.
There is a counter above the reels that shows you the number of each spin, which ranges from 1 to 10. Except for the tenth spin, tube scatter symbols can appear on any spin. If they land, they'll leave a Golden frame behind. The aforementioned frames shall remain fixed until the tenth rotation.
A Tube sign will reproduce itself at a random point without a frame if it lands on a Golden frame. Only if there is at least one frame on the reels during the tenth spin will this extra feature be activated.
Three or more Train Scatters must appear on the reels in order to activate this bonus feature. There will be 9, 12, or 15 bonus spins awarded if there are 3, 4, or 5 scatters. Three Golden frames will always be on the reels when the bonus round starts, albeit their positions may vary with each spin. It is also possible for wilds, multipliers, and cash prizes to activate randomly.
