Ryan Gorer has developed a most interesting series of puzzles. You are given a pipe with a star on it. You must slide the pipe and bend it so that the star lines up perfectly on the blank star.
There are 100 levels. I’ve done 33 of them. Some of them are quite tricky.
One qualm I have with this puzzle: suppose you tap on the pipe to bend it. It may bend to the right instead of to the left. If that happens, double tap on the joint and hopefully it will unbend and then bend in the direction you really want. That part is clumsy.
Starcoaster is a novel type of puzzle that could make it onto the list of Best Puzzle Apps of 2012. Look for the list on December 31: http://gottasolveit.blogspot.com/
