For anyone struggling with not enough coins, get yourself a repeating alarm app and set it to every 4 hours, then you can build up your coins for a much more enjoyable playing experience.
Idk an app for iPhone, but the one I found for Android that works perfectly is Repeat Alarm by Dan's Inc (https://play.google.com/store/apps/details?id=com.kittoboy.repeatalarm)
If you use Repeat Alarm, set your time range to one minute less than the time you collect some coins, then set the end time to one minute before your starting time (thus creating a 24 hour time range).
For instance: let's say you collect some free coins at 1:00pm. Immediately open the Repeat Alarm app and set your time range as:
Start: 12:59pm
End: 12:58pm
When the alarm goes off, open Candy Crush Solitaire and collect your next set of coins. Do this a few times and you're happy
Another tip:
At the end of every level even if you lost and you don't have enough coins for another try, always hit Retry the first time you see a Retry button as this will automatically give you a small number of extra coins.
