William Hill mobile punters now have access to two new HTML5 slots that offer themes as disparate as ancient Rome and samurai traditional Japanese warriors.

Centurion and Spirit of the Samurai have been provided by the Inspired Gaming group, which advises that Centurion is its biggest bonus game yet with eight different bonus games, along with an additional ninth Fortune Spins reward

Spirit of the Samurai offers rewarding Free Spins and an interesting new format; the game has four levels, each one progressively and potentially more rewarding than the last…. and online and mobile players can save progress between play sessions.

There is also the possibility of a hidden fifth level for VIP players who manage to crack all four previous levels.

Dave Hammond, Inspired’s mobile manager, said this week that the two new games had proved very popular in other channels, with a significant demand from operators and players.
