Is the labyrinth rigged for normal players? Someone in my guild did say they won it once in normal but since starting like 120 days ago or so and getting the 5$ and 20$ packs for holy stars almost everytime I've probably used about 300k+ stars and not one jackpot. Do I have to unlock elite mode for as better chance of defeating the boss?
You don't need Elite, just realise your (or anyone's) chance of winning at either level is minuscule.
One of my friends has won twice, but Ive seen people win three or four times in a sitting.
It's like the lottery. Don't get your hopes up. Use it as a chance to get rss and rares.
No. All encounters are random. You can just as easily win in normal stage so there is no need for elite. Some people can win in a round while others might never. Don't give up either way, there are prizes with most hits.
