Time to visit the capital of London and go underground to the famous London Underground for our next stop. With deep history such as being the worlds first underground passenger railway, with 272 stations and been running since 1863. The game background shows one of these wonderful station stops with a train either side of the reel set and many eager passengers waiting on the platform. Visuals have a unique aesthetic due to the darkness in the tunnels.

Going Underground has a classic setup of 5 reels by 3 rows; this includes 20 set pay lines. This slot is high variance with a set RTP of 96.51%, and a max win is yet to be confirmed. You can bet from £0.20 to £125.
