The difference between level 6 and 4 is that you have less colored balls to place on the board before the computer drops the screen one line. You have less shots to prepare a large drop of colored balls to award you the 1.3m bonus. I can play on 8 no problem, but the way I set up some of the boards for big points just won't happen. It's much faster so your stuck having to finish the board and take crappy points not having enough time to build for the 1.3m drop. Just finishing boards will give you a really crappy score by the end of the game. The whole thing is that when I played it a few months ago, it was fine. Now for some reason it's stuck on "6" and can't be changed?! TG doesn't require you to play a game any harder then the settings allowed unless you want the challenge. 4 was the setting so I shouldn't have to play it on 6.(posted 9809 days ago)Steve Krogman
