They will tell you that they are highly regulated but they are not. The bottom line is that Mystic Lake is a rigged casino. Their promotions are cheap and their customer loyalty rewards are laughable or nonexistent. Also, there is virtually no security at the casino and on numerous occasions I have been hit up for money by various riff-raff in the High Limit area. These bettors win the vast majority of jackpots while bettors like me essentially fund them. Their High Limit slots area even caters to the $5 or less bettor. I was told that slot machines are completely random. Then if you lower your bet near the minimum the bonus symbols magically return.
In fact when you bet high on slots the machine’s bonus symbols will mysteriously disappear. The higher you bet the less chance you have of ever getting a bonus on a machine. Their slot machines (even the ones in the High Limit area) are rigged for low bettors.
If you are a high bettor like me stay away. If you like to bet $1 or less on slot machines you will probably have an okay time.
