A rectangle is cut out of a repeating pattern. Pick the fragment whose lines, angles, and rhythm continue the surrounding texture seamlessly. Six levels of progressively complex grids; the top level adds harder pattern types — radiating rays, wave continuations, concentric rings, and a perspective grid converging to a vanishing point.
All six levels are unlocked. Levels 1–5 build up grid complexity one axis at a time; Level 6 cycles five harder pattern types.
