Rule 1 |
Rule 2 |
| In 3×3 questions, each row and each column are consisted of 1, 2, 3. In 4×4 questions, each row and each column are consisted of 1, 2, 3, 4. |
|
|
Rule 3
There are four different calculation signs : +, -, × and ÷ |
|
|
Rule 4 Beside those signs, there is another type of group consisted of grids, which do not have calculation signs. At this time, this grid represents number shown on the top-left corner, as shown in following figures. Important: Numbers of each group can be repetitive but they have to satisfy the rule number one (numbers cannot be repetitive in each column and each row). |
