Low on coins?
Okay, so I just found out an easy way to earn lots of money, but with patience!

Be sure you got another account befriended with you.

1. play hotelcity on the secondary account, and post hire jobs.
2. log into your main account and accept the job.
3. when the "you got the job"-screen appear, you receive 400 coins.
4. refresh the site, and you'll receive another 400 coins.
5. repeat step 4 until you're pleased.

Please reply if it help :3
