Solution techniques

Japanese Crosswords is a special type of puzzle that relies on logic in order to reveal a certain picture.

Japanese Crosswords look like grids of squares with numbers above and to the left. A field of a Japanese crossword is lined both horizontally and vertically with lines. Numbers, shown on the left and above the crossword – describe the groups of painted squares (which go in sequence, no blanks) horizontally and vertically accordingly. The order of these numbers describes the order of location of these groups, but it is unknown where each group starts and finishes. Each separate number means a separate group of the given size (i.e. number 9 – means a group of ninth painted squares in sequence, 1 – a group of only one painted square). Between the painted groups should be at least one unpainted square.

To solve a Japanese crossword you should look at each line/column separately, always moving to the next columns and lines. In so doing the process of solving in each line/column comes to the following:

1. To define the squares which are sure to be painted.

2. To define the squares in which it is impossible to have painted squares – such squares are marked with a cross.

Example of solution:

In front of us, there is a crossword of the size 10x8 squares. We will gradually decipher this crossword explaining every step.

Step 1.

First of all, to define the squares which are sure to be painted. Look at the number to the left we can see numbers 9 and 10; there are ten squares in the rows. That means we must fill in all eight and ten squares accordingly. Click each square once until they are all black.

Let’s have a look at the first line – two central squares are sure to be painted.

Step 2.

After that, have a look at the fifth column. There are first number is 2, next squares should be painted.

Step 3.

Have a look at the sixth column, we have number – 1. The first square in this column was painted. Accordingly, the second square are sure to be unpainted. Put cross this square.

Step 4.

Further look at the fourth column, we have only one numbers in this column – 7. Paint the square that need to be painted.

Step 5.

In the second line, we have group, which consist of two painted squares, we can mark with crosses the squares on the left from deciphered one.

Step 6.

Now have a look at the third line –we have one painted square. Such as all groups on this line consist from one square, we can mark with crosses the square on the left/right from the deciphered one.

In the fifth column all groups are painted (first group consist of two squares, second group consist of three squares). Therefore, unpainted squares must be marked with crosses.

Step 7.

In the third column, we have a group, which consist of five squares. It can be noted that three squares of group already painted. Therefore, two squares down should be painted too.

Step 8.

Have look at the first and second columns – these are completely solved. It means that we can mark all the rest squares with crosses.

Step 9.

Look at the last line; we can paint second square from group, which consist of two squares. It can be noted that fourth column is completely solved; we can crosses the first square here.

Step 10.

We should paint four squares on the right in the first line. The first line is a solved!

Step 11.

Now we should paint groups from six squares in the seventh and tenth columns.

Step 12.

You can see that all groups in the second and third lines are painted. Therefore, we can put crosses on the left and on the right of the deciphered squares.

Step 13.

We should paint groups from fifth squares in the eighth and ninth columns.

Step 14.

We can see that all groups in the grid are painted. Unpainted squares should be marked with crosses. Congratulations! The crossword is completely solved!

We only wish You to have success and a pleasant game!
