0h n0: another simple, free, Japanese logic puzzle

Companion to 0h h1

Late last year I was turned on to 0h h1, a free digital version of the Japanese logic puzzle Takuzu. Developer Martin Kool of Q42 is at it again. 0h n0 is another adaptation, this time taking the puzzle Kuromasu and giving it the procedurally generated, simple red/blue art treatment.

In 0h n0, each numbered blue circle can see that many other blue circles in the same row or column as itself, but its line of sight is blocked by red circles. The goal is to fill the grid with red and blue such that each numbered circle has its constraints satisfied. As a logic exercise, it is more involved than 0h h1, where the solutions do not come quite as easily and the little victories feel a bit more satisfying as a result.

As with its predecessor, it is available for free on Android, iOS, Windows Phone, or in browser. Check it out if you have some time to waste on this fine Friday.
