Arkedo Series

You need to create a shape containing 10 blocks of the same color. A 10 bricks shape will look like a 'T'. You will need a space of 7 blocks wide and 5 blocks tall. Choose a color. 

On line 1, put a block of this color in column 4. 
On line 2, put blocks in every column except column 4. 
On line 3, 4 and 5, put a block in column 4. 

Now you just need to slide the block from line 1, column 4 to make the 'T' shape and unlock the trophy.

The setup is shown in page 4 of the 'How to Play' section of the game (available in Arcade Mode or by pressing  while in game). Here is an actual example just before making the shape:

Note: You will have to do this for one of the challenges in Challenge Mode.
