3 stars because there are no instructions. This is the 1st game I've downloaded from this co. Before I even make a move it keeps flashing the cost of buying coins. Why can't I just pay for the game? How do I know how many coins I'll need - $5 worth or $15?! You expect someone to just spend money without knowing the purpose? I've read the reviews which are positive but cannot find any info regarding coins. Everyone says the game really is free -but not if you have to buy your way thru it.
