A blockade means to occupy several points or points in a row with at least 2 stones. The largest possible blockade consists of 6 consecutive blocked spikes and is called Prime - the opponent cannot get over this blockade, because the highest possible number on the dice is 6. It is advisable to create the blockade in your own home field, so that the opponent (should he be defeated) cannot get out of it or it is more difficult. A blockade is best built between the 11-point and 2-point and try to play further towards your home field during the game.
