In Frazzled, a cobination occurs when either two or more stacks get completed with a single block. The diagram shows how two diagonal or one diagonal/horizontal/vertical stack could be completed at once. Complete the two stacks at once and then your score for the arrangement is doubled. For example, two three-in-a-row diagonals will count for (2)(500+500) = 2000 points! Complete three or more stacks at once and your score for the entire arrangement is quadrupled. The above arrangement of a diagonal, horizontal, and vertical stack will yield (4)(5+100+500)=2420 points!
