Predatory marketing. Absolutely shameful that some developer thought it was funny to make the 'skip' button in their ads in other games scaled down at least 5X (in a game marketed to the elderly), so you can't exit the ad until you click a microscopically small button. And every time you TRY and fail, you open the Play Store listing. This kind of practice should be illegal. I wish I could give zero out of five stars.

I feel the games I have played so far are somewhat challenging. you can get in a bind if you make a move at the wrong time or if you miss a move. pretty much all the games can be won if you don't make a mistake. the best way, I feel, is to look at all the columns when they are initially dealt and come up with the scenario that would work best and then improvise if necessary. all depends on whether your flip cards come up right or.if you're able to make changes on the fly. all in all it's fun.

old classic version better, more simple, and doesn't constantly offer other games, and demand an upgrade repeatedly, which when done is not improved.
