"Different players have different methods of solving levels. Sometimes there are recognizable geometric figures that stand out, which act as guides to remaking the Target Pattern."
"Other times, it's easier to assign a specific direction to the tile: This tile kinda seems to point in THIS direction. Then you can memorize a group of tiles by thinking of it as Up, Right, Down, Left."
"Because most Target Patterns have repetition and/or symmetry, all you need to remember is the small group and how it relates to the whole."
