Line of Four · Four in a Row Strategy Game
Line of Four is a drop-disc strategy game on a 7×6 grid: line up four discs across, down or diagonally before the CPU does. Every match you win levels the CPU up — it searches deeper and stops making careless moves.
How to play Line of Four
- Tap a column (or press 1–7) to drop a disc.
- Connect four in a row before the CPU while blocking its lines.
- Win to level up; a draw counts as half a win, a loss ends the run.
Controls
Tap / click a column — or keys 1–7, arrows + Space.
Tips & tricks
- The middle column is part of the most lines — claim it early.
- Build threats on two different rows so the CPU cannot block both.
