## Basic solving techniques

In this part of the tutorial you will get to know some basic techniques of solving griddlers. The best way of learning them is just solving an easy griddler.

A griddler which uses all basic techniques is Tentacler, so let's solve it. You should remember that there are many ways to solve one griddler and in this tutorial only one of them will be presented.

### Step 1

At the beginning we can look for lines that can be painted entirely. In this example the first row and column have only one clue '10' in description and side lenght of the board is 10, so there is only one possibility of placing them and we can paint these lines.

### Step 2

Now let's concentrate only on rows. We have painted the first column so the first cell of each row is black and must belong to the first clue of description. We can paint as many adjacent cells as are needed to complete the first group. The next cell must be a space. Then we see that second and third column and the row marked with green arrow are completed so we can fill the rest of cells with background colour.

### Step 3

Let's look at the clue '6' in the second row. There are still 7 undetermined blocks, so we can place the group of 6 in two ways, both are marked on the picture, with green and red frame. In both cases 5 centre blocks are marked, so we can paint them.

### Step 4

Proceeding like in previous step we can paint groups marked with green frames.

### Step 5

We can paint all groups in row marked with green arrow because groups must be separated with at least one space. 3+1(space)+1+1(space)+2+1(space)+1 gives 10, which is side lenght of our griddler.

### Step 6

Now we can proceed like in the second step but for columns and paint first group of each column ending it with one space.

### Step 7

In the last column the first group is finished, than is one space and the next cell is painted so the painted block must belong to the second clue, which is '2'. We can paint one more cell (as marked with the green frame) and end the group with the space.

### Step 8

Now we can fill all undetermined blocks in completed lines with background colour. Now notice that in columns: 4, 6, 7 and 9 the only missing group is '3', there are some painted blocks so this group should contain them and there is only one place in each column which can contain as many as 3 blocks, so we can paint them and fill completed lines with the background colour.

### Step 9

There is the last undetermined cell and as you can see in the last row and column lacks the group of one so it must be painted. The picture is finished!
