The classic line-drawing game with the lights off, where you only learn your rival's moves when a box closes.

How to play
Take turns drawing one line between two adjacent dots. Complete the fourth side of a box to claim it and take another turn. The twist: your opponent's lines stay invisible until they close a box, so you play with incomplete information.

Tips & strategy

Hidden enemy lines mean a 'safe' move may not be safe, so weigh the risk
Late game, set up chains so one mistake by your opponent cascades into many boxes
