Update: lowering to 2 stars because they just devalued all my coins by 75 percent. All that work to build them up and now -- poof -- hint prices increase 4x. Makes me not wanna play. Fun game, but fewer stars because ads are long and brutal -- it's a puzzle in itself to click through them without being taken to a download page. A minor thing, but I also find it annoying the daily spinner is clearly not random -- you land on the lowest number at a rate that's statistically nearing impossibility.
