Martin Kool returns with another addictive minimalist puzzler! In this companion to addictive hit 0h h1, figure out how many blue dots are on the field by using the numbers others display when they "see" other blue dots in their row or column, but remember... red dots block their view!

There is one rule the game doesn't state until you've contradicted it, which I just discovered myself:

Every blue circle must be able to "see" at least one other blue circle-- in other words, you can't have a single blue completely surrounded by reds.

I don't understand the meaning of numbers inside circles.

The number in a blue circle is the total number of blue circles above, below, to the left, and to the right of that circle, with no intervening red circles. For example:

``` . . . b . . . . r . . . . B . r B B 4 r . . . B . ```

Here the capital B's are the circles that count toward the total of 4.

(I'm still finding these puzzles a bit too slow-going to be much fun, but I'll stick with them a little longer to see if I pick up a knack for them.)

Argh, I'm used to Range from Simon Tatham's puzzle collection: The rules are mostly the same, but the number INCLUDES the cell doing the counting, and is one higher.

I really really like it, I played every single games of conceptis and welovepuzzle and even in printed magazines I wasn't finding any new games, here is something new to me and I find very enjoyable to find myself consequences of the rules that allow to solve the puzzle without trying things randomly.

Fun. I'm having slow-brain today and so it's a bit of a struggle, in a good way.

Is there one and only one solution to each? It seems like there could be a couple ways out.

So far I had only only solution each time.

Thanks ishanpm for talking about tatham's puzzles, I didn't know it and I like them. If you know other puzzles feel free to tell.
