Yall remember my previous theory?
Since 9 and 10 both control time, I think 11 and 12 will both control flags. If you notice, you have to click 9 to win, click 10 to reset the timer, and click 11 to deflect, so clicking 12 should benefit while playing the game. And also, 9 and 11 moves on the grid, so maybe 10 and 12 will move off grid.
Sorry for typing too much
