Fun until 6x6 – Logic Dots 2 Review

This game was really fun, I enjoyed it and was looking forward to keep playing... but once I got to 6x6 I realized to progress I had to use hints to unlock more levels. I watched a video to get 15 and unlock it, but the next day when I went to play again it said it was locked. I have 0 hints and can't play any of the levels I unlocked using them.
