Sigma Zone (シグマゾーン, Shiguma Zōn) is a game exclusive combination block hissatsu technique.
Sigma Zone is a hissatsu that has only been shown in the game — never in the anime. It is one of the strongest block hissatsu in the game, but has a high foul rate.
Three players are required for this technique. The target first gets trapped in a blue-and-black void, surrounded by the three users. The ground transforms into a green grid. Each of the users simultaneously intersect the spot where the target is standing in a flash, the main user is now in possession of the ball.
- This hissatsu seems similar to Southern Crosscut, although that is only used by one person and is a dribble hissatsu.
