The first Battle of the Block competition
Season 16 ushered in a brand-new twist that threw both Feeders and Houseguests for a loop: enter the Battle of the Block competition. Here's how it worked:
Two HOHs were named each week; then, each HOH would nominate two other Houseguests for eviction. The Battle of the Block would then pool all four nominated HGs and pit them against each other in pairs. The winning couple would be safe from eviction and the HOH who put them up would be dethroned. In turn, the losing two Houseguests would remain on the block and, thus, the corresponding HOH would stay in power—until the next week, that is, when the competition happened all over again.
