-In this situation, both blocks are used to hit the [[bomb]]s at [1, 0] and [1, 1]. The Block Donut Rule is going around to the ''right'' side of the blocks and moving block 2 L, rather than R. The two paths form a donut, which gives the rule its name. While this path is 2 moves longer, it places the block 2 spaces closer to its target, saving ''four'' moves, and thus gaining two moves net. Not all situations trade the two moves; sometimes, Chip will already be on the opposite side, and therefore the Block Donut Rule will be worth four extra moves.
+The Block Donut Rule is going around to the ''right'' side of the blocks and moving block 2 L, then pushing block 1 U and 3L into a bomb. The two paths form a donut, which gives the rule its name. Compare this to starting by pushing block 2 R from the left side. While the Block Donut Rule's path is initially 2 moves longer, it places the block 2 spaces closer to its target, saving ''four'' moves, and thus gaining two moves net. Not all situations trade the two moves; sometimes, Chip will already be on the opposite side, and therefore the Block Donut Rule will be worth four extra moves.
 However, the Block Donut Rule is ''not'' usable in situations where the push physically closer to the target will impede [[Chip]]'s pathway, or cause the block to be either technically further away from its target or completely unusable.
