Town hall 8 attacks are mainly divided into 3 camps: Dragons, Hogs, and GoWiPe (Golems, Wizards and Pekkas). We'll go through each camp with a few examples of how they work.

GoWiPe Yourself Already!
GoWiPe and its variants (GoWiWi, GoWiWiPe, HoGoWiWi and HoGoWiPe) are mainly used for bases that doesn't have many compartments. Wide open spaces are what makes these attacks so attractive as the Golems would have access to a big proportion of the base without getting stuck on walls. It must be noted that this attack strategy is generally considered to be a 2 * attack strategy at higher level town halls, and thus should be avoided like the plague.
