GOAL
Solve 4×4 Flow Free boards as fast as possible. Connect all dot pairs and fill every cell to clear a board, then move on to the next one.
RULES
- Drag from a dot to draw a path through adjacent cells.
- All dots must be connected and all cells filled to clear the board.
- Paths cannot cross. Dragging over a path truncates it at that point.
- The clock runs continuously — keep solving until time's up.
SCORING
150 pts per board solved + 5 pts per second remaining when time runs out.
