Online casino games developer Wager Gaming Technology has just launched the second video slot in its Wild X series with aficionados at Liberty Slots now among the first to be able to enjoy the new three-reel game and its ‘must-win’ progressive jackpot feature.Known as Ultimate 10X Wild, the new video slot is the follow-up to the developer’s 7x Lucky 7s title and has been specifically designed to work on mobile devices.Just like its predecessor, Ultimate 10X Wild comes complete with a progressive jackpot that is guaranteed to pay out by the time it reaches $25,000. The odds of triggering this pay-day get shorter the closer the overall amount gets to this ‘must-win’ threshold while players that manage to collect a pair of wild symbols can multiply their wins by up to 100 times the triggering bet.“With ten winning combinations and an estimated return-to-player of more than 96 percent, this game is destined to provide some significant pay days for some lucky players,” said Mark Ramirez from Liberty Slots.“As in 7x Lucky 7s, the last Wild X game released, Ultimate 10X Wild also has a ‘must-win’ progressive jackpot that is guaranteed to payout by the time it reaches $25,000. The jackpot can be triggered at any time by any coin value combination although playing more coins up to a maximum of three increases the chances of winning this jackpot.”Last month saw a player known as ‘Kim D’ become one of the first to take home the progressive jackpot tied to 7x Lucky 7s. The Pennsylvania resident banked $19,429 off of a single spin after earlier placing a series of small bets.“I didn’t even know about the ‘must-win’ feature so you can imagine how surprised I was when my three cent bet paid out that much,” read a statement from ‘Kim D’.
