6426 is essentially impossible now. It's not the board I see on YouTube plays. It's solid blocks across the bottom and the goal is to bring a bunch diamonds to the bottom and you get no line blasters ever. The bo us is a paint bucket and there's one of those flower things that does noting.
I'd like being forced to play if you told me beyond theinitial box how many levels you have win and then when you win how close to goal you really are. Since the graphic doesn't change for each level, you really have no idea where you are.
On my Android, I swipe up from the bottom and hit the back arrow to turn it off. I hate it, too. I get the "offer" to play it multiple times between games.
