Untangle comes from Aman Kapoor. It's a 'minimalist' game of puzzles where the object is to send diamonds along paths to their final destinations and hopefully not make them crash.
1. The sequence is vital.
2. Some diamonds move in pairs.
3. Some diamonds can only travel on an odd or even move counter.
I completed all the levels a few days ago. Not sure how many: maybe 40.
Unfortunately, I cannot open the program anymore! Nor can I access the itunes link! So I cannot post any pictures.
If this game becomes available again, give it a a shot. It's free.
