It's noughts and crosses, but on a much bigger grid and you don't stop at the first three in a row. Take turns tapping any empty square to place your mark. Every time your placement makes a run of three or more of your marks you score: three in a row is 3 points, four is 5, five is 8, and longer lines score even more. Line up two runs through a single square at once and you bag a LINKED bonus on top. You keep playing until the whole board is full, and whoever has the most points wins.
Because you only ever score the extra value a move adds, there's no double-counting — your score always matches the lines you've actually built. That makes it a proper little strategy game: extend your own lines, block your opponent's, and hunt for squares that cross two lines at once.
Play one-player against the CPU on Easy, Normal or Hard, or pass the phone for a two-player game. Pick a board size from a classic 3×3 or 5×5, through 7×7 and 10×10, up to a sprawling 13×13. There's nothing to install and no account.
How is it different from normal noughts and crosses? The grid is much bigger and you play on for points, scoring every row of three or more instead of ending at the first line.
What are the controls? Just tap an empty square to place your mark.
How does scoring work? 3 in a row = 3, four = 5, five = 8, longer scales up, and crossing two lines through one square adds a LINKED bonus.
