I have played these a few times now and Heres what I think.... If you start to play and give the machines a resonable amount of spins and the Bonus is a no show, you are not going to see a big screen win anytime soon. I believe the frequency of the bonus even though they usually pay very little is a good indicator of the chances of you getting that amazeing screen win. Anytime I have won a couple hundred on a 2 cent machine off these, the machine was first active with the bonuses even though they were not to profitable, eventually came the screen win. I also have lost a lot playing and waiting for the bonus, lol thats how I noticed the pattern. So If they don't want to bonus, move on!
