In this exclusive Zap2it clip from “Survivor: Cagayan,” watch the remaining castaways compete for the Immunity Idol in one of those delightful counting challenges where the amounts of various objects equal a combination lock.

The different strategies are interesting — Tony and Woo are quickly doing a couple numbers at a time, while Kass appears to be trying to remember all six different numbers at once. Risky strategy.

Also in the episode, titled “Havoc to Wreak,” CBS says in the description, “One castaway’s paranoia threatens another’s stake in the game, and Tony’s closest confidant is wooed by another alliance.” Innnnteresting.
Who do you think it is?

“Survivor: Cagayan” airs Wednesdays at 8 p.m. ET/PT on CBS.
