Why Choose This Activity
Line of Four fits Sharp Mind sessions when someone enjoys a familiar connect-four style game against the computer. Gold versus blue discs are easy to tell apart, and turns alternate automatically. The goal is simple: be first to line up four in a row.
Familiar drop-a-disc rules with five AI strengths let you match challenge to confidence without needing a human opponent.
How It Plays
You play gold; the computer plays blue. Tap a column arrow or the column itself to drop your disc into the lowest open spot. Take turns until someone connects four across, up-down, or diagonally. Winning discs flash with a yellow ring; a full board with no winner is a draw.

Facilitator Tips
- Start on Relax or Easy while learning column tapping and disc falling.
- Watch for three in a row - block the computer before it makes four.
- Center columns are often the strongest places to play.
- Try setting up two threats at once so only one can be blocked.
- Changing difficulty after Start restarts the game.
