# Dividing Grid by Numbers

Separate the grids below into groups of squares, such that:

1. Each group contains exactly one numeral.
2. The number of squares equals the numeral in the group.

For example:

Could be solved liked this:

Hopefully this isn't too easy! There may be more than one solution for each grid.

• The puzzles seem too unconstrained to have unique solutions. You might want to take a look at Nurikabe, which has a similar idea with additional constraints.

• I learnt 2 new things so not complaining :D Commented Jan 22, 2015 at 6:17
• easy and mot unique are not necessarily bad. I think it is a nice puzzle, and as you have said yourself in the meantime: you can make harder variants the next time. Commented Jan 22, 2015 at 6:41
• Fillomino is another similar puzzle type. Commented Jan 22, 2015 at 8:45

Solution to all 3:

Sorry it's a bit sloppy but conveys the idea adequately. I either got lucky or am good at these (or they were easy and had multiple solutions), I had to backtrack like twice total for all three.

• Wow that was quick! Looks like there are quite a few solutions, I'll have to find a way to make it harder. Commented Jan 22, 2015 at 5:55

Simple guess work with no pure logic and easily done.

Some suggetions to make it harder and the solution unique:

• If say a number is 7, add multiple sevens to ensure that all the 7's form a part of the same block or probably a wall of one of the block. Use different colour to help in distinguishability. (Pseudoku: A Game of Finding Order in Chaos)
• Remove a number, say just have 1-7 and remove 8. Let the user figure out where to place 8.
• border issues: Add constraints that
• 2 cannot border its multiples likewise for 3.
• A number cannot border its consecutive number, etc.

Many ways to make this what you intend to. Put your thinking cap and puzzle us :)

• Aww I was hoping it would take longer.. Let me know if you've got any suggestions on making it more challenging :) Commented Jan 22, 2015 at 6:04
• Please find my comments to metamorphose the puzzle to a newer level. Just a few for you to get started :) Commented Jan 22, 2015 at 10:16
• Wow thanks so much! I really like the idea of not being able to border consecutive numbers. I might have a go at adding/removing the numbers as well and see how that affects it. I thought of making each block more like a snake with a number at the start and end, but then I realised there's already game really similar to that... Commented Jan 23, 2015 at 0:29
• a minor mistake in last image label 8 contains 7 squares and label 5 contains 6 ;) Commented Jan 23, 2015 at 10:34

It does seem pretty easy, and I imagine there are a lot of solutions for each one.

These may also contribute to the answers.

• I like the colours! Commented Jan 23, 2015 at 0:21
