# Block-a-Pix решение

Block-a-Pix puzzles consist of a grid with clues scattered in various places. The object is to reveal a hidden pixel-art picture by dividing the whole area of the grid into rectangular blocks so that each block contains one clue, the number of squares in the block equals to the value of the clue, and the filling color of the block is according to the clue.

# Block-a-Pix step by step solution

The best way to learn how to solve Block-a-Pix puzzles is to see a puzzle solved step by step from beginning to end.

## Step 1

Solving Block-a-Pix always starts with the blocks of 1 which are simply filled according to their color.

## Step 2

The next step is to look for blocks which clearly have only one way to fit in the grid. These are usually smaller blocks such as the dark-blue 2, the beige 2, and the light-blue 3, and even larger blocks such as the light-blue 6 as shown below. In all these blocks it is easy to see that there is only one way they can fit in the grid.

## Step 3

Let's look at the square with the light-blue dot on the left side of the puzzle below. It is obvious this square can only belong to the block of 3. Next, let's examine the dark-blue 14 in the bottom area of the puzzle. There are four combinations for a block of 14: 1x14, 14x1, 2x7 and 7x2. However, because of the rule that each block must contain one clue, the only block which can fit in is 7x2 as shown below. We can also proceed with other easy steps, the dark-blue 2, the beige 2, the light-blue 2 and the red 2.

## Step 4

On first look it seems it's not possible to solve the light-blue 7 on the right edge of the puzzle. However, since a block of 7 can only be 1x7 or 7x1, and since it can only fit vertically and only in one way, we can proceed with this step. In addition, we can solve some more easy steps, the red 4, brown 4 and dark-blue 3 as shown below.

## Step 5

Now let's look at the square with the light-blue dot in the top-right area of the puzzle below. It is obvious that this square can only belong to the block of 12. However, since this square is in the corner, there is only one way to complete this block. We can also proceed with some additional easy steps, the beige 2 and the light-blue 2.

## Step 6

Similar to the previous steps, the beige and the dark-blue dots can only belong to the beige block of 2 and the dark-blue block of 6 respectively. Since there is only one way to place these blocks they can be completed as shown below.

## Step 7

There are now some more easy steps, the beige 2, the brown 4 and the light-blue 2 which can be completed.

## Step 8

There are now two easy blocks to fill and we can complete the puzzle. The Block-a-Pix puzzle is solved, revealing the picture of a surfer.
