Connect! is a topology type puzzle app. The object is to connect a path from A to the furthest level. Your path may go horizontally, vertically, diagonally. You will probably have to zigzag.
The first 40 levels are free. And they’re easy. But the next 120 levels are harder and cost $1.99.
Right now I’ve solved all 160 levels.† The puzzles are not very difficuly. But they’re fun and perfect to play when ‘watching’ tv news shows.
