Get your King, the grey router with black controller or the yellow router with orange controller, between respectively the grey controllers or the yellow ones, beware however not to get enclosed by your opponent.
In general each player has three moves, for example rotate three towers over one position or one tower over three positions, clockwise or counter clockwise. Equal to Crossing there is a 1-2-3 start-up sequence. You are only allowed to rotate a tower when you outnumber your opponent, being equal will not do!
The grey and yellow routers including the Kings count as one, the black and orange routers as two.
