If a piece lands on a square with a playing piece of the same colour then this is known as a "blob" and is basically a barrier. An opposing piece is not allowed to jump over them, but friendly pieces can. The two ways an opposing piece can get by a blob is to destroy it, or by using an adjacent friendly blob to jump over it. A player can destroy the barrier by landing on an opponent's blob with a blob of their own or to "six" the blob off. To do this they will need to have a playing piece adjacent to the blob and then on their turn throw X + 1 six where X = the number of playing pieces forming the blob. Note that if the blob is on its own colour doorstep, then an additional six (i.e. X + 2 sixes) must be thrown to remove the blob and exit the homebase.
