Unclear game play elements

This game has elements to it without any info on exactly what a player would be wasting their coins. After each round that window pops up detailing round statistics. Several of line items are a mystery to me! Yet, this app wants me to waste coins - which are ridiculously difficult to accumulate at times - on something app developers dont bother to explain.

Just played couple more rounds. I am deleting this game.
