i play everyday and im collecting the little hearts but nothing is happeing with my bar ? is it not working or must i collect so many for bar to start going up ?

if you are playing with coins, it takes a lot to get the bar to move. You may want to remove the app and re install it. There was an update so it might help..... sometimes I have used YC and the bar fills up fast. Good luck.

I'm wondering that too Thanks for answer!

If you click on the bar at the top and it will tell you how many you need. It takes 1000 to get the coins and then another 2000 to get the cash. 3000 more to get the item. 6000 in total to get the item.
The more you pay to play the quicker you fill up the bar. I got the fluttering wings, but they cost me about a million in to total.. lol
