I've heard others say they just constantly increased their bets and got lucky and were able to finish it in less than 24 hours. but it took constant babysitting and spinning.
If you join a good club there are good rewards, and you can always get chips to keep yourself alive like from the links and the hourly bonus. I got to 4B three times and ran out of chips about 12 times. I spun for literally 6 days straight on like 7.5M chips. moving forward I mainly used the 1st link as it had the best 'daily' free coins. When I first ran out of chips, I started using these.
