Puzzle 3-1
Moves required: 2

Notice how many stars there are... what does that mean? This puzzle is interesting in that it has a normal, relaxed solution, and then another which requires you to make the second move within a certain time of the first move.

Puzzle 3-2
Moves required: 2

Count your blocks! This is a good example of how thinking about what columns the blue blocks must be in can be very useful. Only one way also makes the greens work.

Puzzle 3-3
Moves required: 2

By now you know better than to just try switching the middle panels. This does not always work, but for some puzzles such as this one, it is best to think in layers; if different colors are stacked, get one color to always be on the top, keeping the same color order down the stack. You will have some unstacked columns as well.

Puzzle 3-4
Moves required: 2

Sorry, matching yellow first will just not work. This is also a situation where the previous think-in-layers suggestion will not work, as there just are not enough moves for it. So if yellow's not the first match, what has to be?

Puzzle 3-5
Moves required: 3

This puzzle is an exception: you will be making a match prior to your final move. It also has a very tricky alternate solution. Count your purples, and keep in mind what has to happen for them to all clear.

Puzzle 3-6
Moves required: 2

Well this sure looks a lot like 2-6, doesn't it? There are actually numerous combo/chain results that can occur, depending on which blocks you move.

Puzzle 3-7
Moves required: 2

You may quickly notice after trying that no matter which purple you move out from between the reds, some of the reds will clear before you can get rid of the other purple. Which panel of a 5 combo must be last to switch?

Puzzle 3-8
Moves required: 3

Well that looks ridiculously similar to 2-4... In actuality, this setup creates an additional solution.

Puzzle 3-9
Moves required: 2

Remember, a group of 4 panels must either be all in the same column, or in 4 different columns. Take a look at those light blue panels...
