Sorry nr. 3 idee in a row, hope it´s usefull.....
I like gamble, and the games i play other than strategy games is with a taste of gambling,
like "wheel of fortune"
you bet, you spin, you either gets crap, nothing, or the chance to gather a great thing.
But maybe a wishing well is a much better idee
We have waterwell ...
why not have a wishing well and make a wish once a day with a free coin
, and if you wanna bet more it will cost you...
That way you could also get some real money into the game,
so all your hard workers behind this game will be payed for many hours work,,,,headache ,,,and no sleep ...
Keep up the great work you do all, becouse its sure worth it
