Best 631A Tactic • Fortress Block & Single-Punch Counters

631A is a deeply structured formation that prioritizes defensive security above everything: six at the back line (4CB + RB + LB), three central midfielders (2 CM + 1 CAM), and a lone striker. It’s built to deny space, absorb pressure, and strike with one clean counter. The formation’s strength is stability; the risk is isolation of your striker and a lack of natural width in attack. Below, you’ll see the exact 631A tactic setups by strength bucket, displayed in the same grid style as your tactic overview.
