n-Challenge Logic Puzzle

The GOAL of the puzzle is to arrange all the tiles in numerical ascending order, starting from the first row.

The RULES are simple:

- Initially you'll find the odd and even tiles on separate rows. You can only move the external tiles of the puzzle and only one tile at a time.

- Each numerical tile can only be followed by a tile of greater value.

- Be careful! With advancing levels some lock tiles appear. They can be eliminated only if accompanied with other lock tiles in a blank row of the puzzle. You can move the lock tiles, but you can’t move the numbered tiles on a row containing a lock.
