A little logic, every day.
FiveToNine is a number puzzle with one simple twist. Thick walls split each
row and column into segments — and every segment must contain the numbers 1
up to its length. A two-cell segment holds 1 and 2. A five-cell segment
holds 1 through 5.
That one rule changes everything. The same number can appear twice in a
row, as long as a wall stands between them. Easy to learn in thirty
seconds, and deep enough to keep you thinking.
