We have 8 of these back to back. The thing i noticed with them is people dont play max bet, in fact its looks like the vast majority at my local dont do it. I go in on like a Weds aft, i ck all 8 machines and rarely was the last bet on any of them for 200 credits...I start at the 1st machine with a $100 bill . Bet max bet 5 times and cash out and go to the next 1. I do all 8. Ive probably done this 7 or 8 times and ive never done all 8 without playing the bonus at least twice. ive cashed for over 300 twice and only lost once for $60 bucks.
Its a $2.00 max bet and yet people sit there for hours and play a buck a spin. I take a break from poker, walk upstairs hit these machines and im back in 15 mins...usually smiling......lol
