Mostly I like these games, but twice when playing Sultans, an ad to install solitaire popped up with NO OPTION to close or cancel. You HAVE TO install to continue. I will not be finishing Sultans, and if this happens in the next game, I will be done with AE Mysteries. Based on developer response, I tried the game again and the offending ad was gone. Excellent response time and quick fix. Not sure how those ads got in there without developer noticing, so maybe points off for quality control? Game is challenging, and I will be looking forward to the next.
