SEQ comes from Thomas Castel and is an interesting puzzle app! The object is to draw paths, counting down, from each colored number to any of the zeros on the grid.
Here’s where it gets interesting: some squares can/must be used by both sequences. And the key is figuring them all out.
SEQ has 160 levels: I’ve done 122 levels so far.
The first 40 levels are free. I enjoyed them, so I paid .99 for the next batch, and then another .99 for the remainder.
Definitely worth your time. SEQ could land on the list of Best Puzzle Apps of 2012.
