Futsal systems live or die on the pivot's spacing and how fast the cierre can step into midfield — this editor lets you place all five outfield roles by hand instead of forcing them into a soccer-style grid.
The 1-2-1 diamond gives you a fixed pivot target and clean passing lanes down both sides — the default choice against a settled defense. The 2-2 box trades that target for two rotating attacking mids, useful when your team circulates well but lacks a strong finisher with his back to goal. 4-0 drops the pivot entirely for a fluid, no-fixed-positions rotation that punishes teams that mark positions instead of players. None of these are right or wrong in the abstract — they're a bet on which of your five players creates the most danger, and moving pieces by hand here is how you test that bet before committing to it in a session or a match.
