Pic-a-Pix Classic 2 (EP)

In order to earn a medal for a puzzle, you need to complete the puzzle without using the "Fix" option. You can access the Fix option by pressing , but you won't actually use Fix unless you press . You can access the Fix screen as many times as you want, and it is actually very helpful in checking moves. If you make a move but aren't sure if it is right, you can press  and you will see how many errors there are. Complete all the puzzles without activating "Fix" and you'll get all the medals.
