Okay game – Slidey®: Block Puzzle Review

Earlier this week. I paid for the no-ad option and I’m still seeing them occasionally. ? I am wondering what’s up with that. I rather like this game. It gets frustrating sometimes, but what game doesn't? The problem I have is not really understanding how the scoring goes. It seems like I've done really well and I've only scored 500 points. An explanation of some kind would be nice.
