Purchase Advice
I love these games (dottello, dotello slide, etc). However, critics are correct that you will very likely have to make purchases to advance to some levels. What I’ve found useful is to (1) wait until a discount pops up, (2) make a purchase to remove the ads and (3) then spend the points on unlimited hearts Some draws from a particular level are easier to navigate through. Also, if you do need to purchase a particular tool, after playing a level a number of times in succession, you’ll know what tool you need and when to use it. I usually spend $10 to get 400 points and then buy 7 levels of unlimited hearts for 100 points. With luck that gets me thru 28 levels. The time I waste playing the game is irretrievable, alas. So you should really ignore my advice and take a walk or something instead of playing this game. :)
