Online casino games developer Wager Gaming Technology has this week launched the inaugural video slot in its Wild X series with desktop and mobile players at Lincoln Casino among the first to be able to enjoy the new three-reel 7x Lucky 7s with its must-win progressive jackpot feature.Lincoln Casino declared that 7x Lucky 7s is ‘shaking up the slots world’ as its wilds trigger ‘amazing features and massive multipliers’.Players that manage to collect one wild while enjoying the new 7x Lucky 7s will see their wins multiplied seven-fold while getting two of the symbols will see any prize increased by 49 times the triggering wager.However, Lincoln Casinos stated that the game’s ‘most exciting feature’ sees its progressive jackpot guaranteed to pay out before reaching beyond $25,000. It explained that the odds of triggering a pay-day get shorter the closer the overall amount gets to this must-win threshold while a subsequent double-up gamble bonus game gives competitors the chance to further increase any wins.
