The WGS 20,000 Leagues slot is inspired by the same-titled 19th-century novel by Jules Verne. The French novelist covers in detail an intense under the sea adventure of Captain Nemo and his crew. WGS Technology did its best to depict the eventful voyage and translate it to the casino language.

Our conclusion regarding the WGS 20,000 Leagues slot is that there are other fish in the sea – literally. This marine video slot is enjoyable to look at and fun to play but the low RTP impacts the outcome. Here at, we are brutally honest and will not recommend a bad slot. We prefer player-friendly casino slots with high payouts and payback percentages. But WGS could do so much better with all its innovation and creativity.
