NoThree or No-Three-In-A-Row

Initially you start with a square board that has a few Xs and a few Os.

Fill the rest of the board with Xs and Os, subject to these three rules:

- no three consecutive Xs (on any column or any line)
- no three consecutive Os (on any column or any line)
- each line and each column contains as many Xs as Os.

Every puzzle has a unique solution.
