The Basic Rules of Kuromasu
Just as other Nikoli puzzles, Kuromasu puzzles are highly addictive and very challenging. How many white cells are visible from
a position in the grid. The lower clue numbers are easier to solve and can be a good starting point for the completion of the Kuromasu puzzles.
We offer free printable Kuromasu puzzles in 3 difficulty levels: easy, medium and hard.
Before you print them, please have a look at the following (easy to understand) rules of this Nikoli puzzle.
1. Cells must be colored (black) or stay white
The main objective of
the game is to decide which cells in a grid must stay white and which must be colored, blackened, shaded or whatever, following the
rules of the Kuromasu logic puzzle.
2. The numbers equal the white cells that can be seen from that cell, including itself
Some cells in the grid have numbers printed in them and the objective that from that cell (including itself)
you need to have a clear view of only white cells. In our example you see the number 9 having a clear view of 5
white cells above and 5 to the right (including the 8). So including itself it has 10 white cells connected horizontally or
vertically. This is obviously wrong. The 9 in the last column is done right though: 5 white cells in its row and 4 in its column.
3. Numbered cells may not be black or colored
A very simple rule this one: numbered cells are white and may not be colored. The numbered cells are part of their number group.
The 2 in our example is colored yellow,
thus wrong. The numbered cells are part of the answer.
4. Two black/colored cells may not connect horizontally or vertically
Two blackened,
colored, shaded, or just non-white cells may not connect each other horizontally or vertically. In our example on the left
you can clearly see that this rule is broken. However, the colored cells may connect diagonally.
5. All white cells must be connected horizontally or vertically
White cellls need to form a continuous group and must all be connected horizontally or vertically. As you can see in our example on the left, we have isolated the 2, which creates its own group of white cells. This is not allowed.
Kuromasu Puzzles are great way to boost brain power
Kuromasu puzzles, or kurodoko in Japanese, are very much suited to keep your brains in shape. The visual and logic elements of the puzzle will keep you challenged and can serve as a great mental workout. It's not just our bodies that need a workout, also our brains need to be trained as much as we can. A strong body comes with a healthy mind.
Problem Solving
Solving Kuromasu puzzles or other logic number puzzles increase both your cognitive and problem solving skills. If you are able to solve Kuromasu puzzles, you will be able to solve many other problems as well as you can strengthen your meta cognitive skills by doing brain teasers.
Visual Perception and Memory
Solving Kuromasu puzzles has a great effect on our visual perception. You need to see and analyze cell combinations, giving our Occipital Lobe a lovely workout. Finding proper cell combinations strengthens our visual and scanning abilities significantly. Your spatial intelligence and short term memory will be tested and challenged!
Critical Thinking
Kuromasu puzzles can be quite tricky and the solutions might not always be easy to find. Critical thinking and the ability to take risks, or guess which combinations need to be eliminated, are needed to solve the Kurodoko problems. Trial and error is is an ability that you can and must practice.
