MinuPlu Rules
- All cells of a MinuPlu have to be filled in with numbers. The possible numbers range from 1 to the size of the MinuPlu. For example, in a 4×4 MinuPlu there are the numbers 1, 2, 3 and 4.
- Each number must appear exactly once in each row and each column. (However, in contrast to Sudoku, there are no blocks where this must be fulfilled as well.)
- Each region surrounded by a thick line contains an arithmetic operation (addition, subtraction, multiplication or division) and a result. The numbers in each such region must yield the indicated result when combined by the corresponding operation.
Note:
- Regions may contain numbers more than once as long as rule 2 is not broken, see region [36 ×] in the above example.
- Regions with subtraction (−) or division (÷) consist of exactly two cells. There are no special rules determining the order of the numbers therein, see region [2 ÷] or [1 −] for example.
- By the way: MinuPlu is pronounced mee - 'noo - ploo.
