3-In-A-Row on BrainBashers is a two-colour grid puzzle in the Binairo or Takuzu family. You fill every square blue or white so each row and column has equal numbers of both, and three of the same colour never sit together in a line.
About 3-In-A-Row (BrainBashers)
3-In-A-Row is BrainBashers' version of the puzzle sold elsewhere as Binairo, Takuzu or Tango. The grid starts with a few blue and white squares fixed. You colour the rest so that every row and every column ends up with the same number of blue and white squares, and nowhere do three squares of the same colour line up next to each other, across or down. The site also lets you show the squares as X and O instead of colours.
Kevin Stone's site posts 6x6, 8x8, 10x10, 12x12 and 14x14 grids every day, each at Easy and Medium, with an 18x18 weekly special. Along the edges the play page counts how many blue and white squares each row and column holds so far. There are check, answer, print and restart buttons, an option to show mistakes and an optional clock, and the help page has a walkthrough.
The puzzles change at midnight GMT or at the time zone you choose, and the date list keeps the last four weeks of grids. Random easy, medium and hard buttons and a New button give extra puzzles beyond the dated ones. No adverts, no account.
It suits players of LinkedIn's Tango who want bigger grids and more of them, and the 6x6 is a quick warm-up.

Tips
- Two blues side by side force white at both ends of the pair.
- A gap between two blues, as in blue-gap-blue, must be white.
- Once a line has its half of one colour, fill the rest with the other colour.
- Use the edge counts of blue and white squares to see which lines are nearly finished.
