LOGTES Rules
Fill in the empty cells (circles) with numbers from 1 to 9 as follows:
Only even numbers may be used in the white cells, and only uneven numbers in the yellow cells.
The same number may only be used once in each row, column or diagonal.
Each LOGTES has 2 diagonals running from one corner to the far opposite corner.
The numbers in the grey squares are the sum of the numbers in each corresponding row, column or diagonal.
When filling in the cells try not to guess but to think logically.
The same numbers may be used several times in a LOGTES as long as they are not repeated in a single row, column and diagonal.

Figure 1 shows a LOGTES with 9 cells. The numbers in the grey squares to the left of each row, at the top of each column, or at the beginning of each diagonal are the sums of the numbers that should appear in the cells in each corresponding row, column or diagonal.

Figure 2 shows the solution. The white cells contain even numbers and the yellow cells contain uneven numbers.
The cells contain 3 different numbers in each row, column or diagonal, and the sums of these 3 different numbers appear in the corresponding grey square.
