Unleash A Mercenary is an online casino game that Incentive Games and bet365 jointly developed. The idea of the game is based on Mercenary X, an exclusive bet365 game created using the xWays, xNudge, and xSplit elements of No Limit City. The 6 Horses Challenge, which was introduced for Royal Ascot back in June, is not the first game produced by the two companies. A weekly grid game with the possibility to win free spins and other prizes will be one of the game's exclusive bonus elements in Unleash A Mercenary.
