5 in a Row: Notebook
In 5 in a Row: Notebook, you play on a sheet of graph paper against a friend or the computer. The rules are simple: line up five of your symbols in a row. You can share one phone for two-player matches or play against the AI. In the menu, choose how many rounds your paper battle will last. This notebook-style tic-tac-toe variant shows who is more attentive and quick-thinking.
How to play?
Tap an empty cell to place your X or O. Make five in a straight line or diagonal to win the round. Before you start, open the settings to pick the board size and decide who moves first. If the computer is too strong, you can watch a short video to get another chance while lowering its score. Your goal is not only to build your own chain of five, but also to block your opponent from doing the same. Adjust the field to your liking and see how fast you can line up all five symbols.
