Line of Four
Drop, block, connect.
▶ Play nowThe classic drop-a-disc board game, head to head. Claim four in a row — across, down or diagonally — before your opponent does. Play a friend through an invite link, or take on a bot that actually plans ahead.
How to play
Tap a column to drop your disc. Get four of your colour in a row in any direction to win. The board fills from the bottom, so think about what you are building for your opponent as well as for yourself.
Get colleagues playing together during a security campaign — engagement, not knowledge.
This one carries no teaching content of its own — it is here to get colleagues playing during an awareness campaign. We would rather say so than dress it up as a lesson.
Play with a friend
Open the game and choose “Play a friend” to get an invite link you can paste into a chat. You take turns; the board is kept by the server, so nobody can edit their way to a win. If nobody joins before the countdown ends, a bot takes the empty seat so you can still play.
Controls
Tap or click a column. Keyboard: arrow keys to choose a column, Enter to drop.
