Hey guys! I know a bunch of you were asking how I solve these puzzles so fast every time, so I will fill you in on a little secret. There's a pretty simple algorithm for solving the puzzles in part 3.
Let's start with the 4x4 puzzle because it is cake! In the 4x4 puzzle, you have four rows of lights in four columns. You start by turning all the lights on the first row. To do this, you press the button right below the lights that are off in the first row. Continue doing this to row 2 and 3. That's it. The puzzle will be solved EVERY time.
In the 3x3 puzzle, there is a chance there will be a few lights left off after you chase down the lights. Based off the lights that are off in the bottom row, you will hit a certain combination of lights on the top row. Once you have hit all the lights that need hit on the top row, you will chase the lights down again until all the lights are lit. If all the lights are lit, then you hit the right combination and you have solved the puzzle. If you have lights lift over, then you hit the wrong combination.
The following chart has a list of all the possible combinations that you should see in a 3x3 puzzle after you chase down the lights. The black dots are considered off.
Now that you have the basics and an understanding of the puzzle algorithm, you can now master the 5x5 puzzle. You do the exact same thing you did in the 3x3 puzzle, except you have a new combination of lights. The following chart will tell you the combination of lights to hit in row one based on the lights that are lit in the bottom row. Once you’ve hit the appropriate lights, then you chase the lights down again for the solve! Piece of cake!
In a 5x5 puzzle, say you chased down the lights and you were left with this combination in row 5 after all the other lights were on: Off, On, Off, Off, On. The chart says you need to hit light 5 on the top row. Once you hit that light, you chase the lights down and it will be solved. If not, then you messed up somewhere. If too many people are having problms with this, I will try to explain it a little better and maybe put up some better examples.
EDIT: I will try to get a solution made for the round puzzle, but I have only done it once. I have a pretty good idea how to solve it, but I just don't have enough practice at it to say for sure. I guess I'll try to sit down and iron it out after class today.
