• Everyone gets the same boards in the same order. Solve one and the next appears instantly.
• Connect each pair of dots and fill every square. Pipes can't cross.
• Bigger boards are worth more: 5×5 = 1 point up to 11×11 = 7 points.
• Skip a board you're stuck on, at the cost of a 5-second lockout.
• Most points when the clock hits zero wins. Ties go to whoever got there first.
• Practice is a solo run against your own best score. It doesn't affect your rating.
• Tug of war: each solve pulls the rope your way. Get three boards ahead and you win on the spot.
• Knockout (lobbies): one board per round, the last player to solve it is out.
• Twists (lobbies): Fog hides dots away from your cursor, Memory turns dots white after 3s, Spin rotates the board, Mirror flips your controls.
