This is the game for them. Played 5 games after installing this; got treated to an ad after EVERY GAME. After the fifth game, the same ad ran TWICE in a row, then hung at a black screen. Too bad. Don’t like the ads? $24 per year. That’s why they don’t want to just put a price tag on CastleSolitaire - it’s only a one-time purchase. Instead, you can subscribe to an ad-free experience for $24 every year. Sorry… not into subscriptions. Or extortion. UPDATE: After a few weeks of trying to play, my opinion has only gotten worse. Three games, then iPad freezes up. Or restarts. Every time. If you really need to bombard people with ads, at least get them to work properly. If other Mobility games are like this, forget it. I attempted several times to contact the, through their “in-game” support links, but they’re useless - so maybe they’ll read this. On second thought, after looking at all the other negative reviews, it looks like they simply have an auto-reply that answers nothing.
