With the finale just two days away, the final three contestants on Big Brother 15 have been preparing for the final eviction and the end of the game on the live feeds.

Houseguests: Andy Herren, GinaMarie Zimmerman and Spencer Clawson

After Thursday night's live show, the final three competed in part 1 of the final HOH competition. The competition involved the houseguests roller-skating on a rink while holding onto a bar. The last houseguest standing was GinaMarie, meaning she was automatically advanced to part 3 of the competition.

To determine who GinaMarie would face off against in part 3, Andy and Spencer squared off in part 2 over the weekend. Both houseguests were tasked with digging through sand to find crabs with the faces of the evicted houseguests on them. They then had to recreate each week by putting the faces in order with who won HOH, who was nominated, won who Veto and who was evicted each week.

The competition was timed and whichever houseguest completed the board in less time would win. Andy was faster than Spencer and won the competition. Andy will face GinaMarie on Wednesday's live show. Whoever wins will automatically advance to the final 2 and have the sole power to evict one of the two remaining houseguests.

All three houseguests have made separate deals with each other to ensure their safety. Andy made a final 2 deal with Spencer when there were still five houseguests left, so he may honor his deal with his closest friend in the game. However, after Andy won part 2 this weekend he struck a deal with GinaMarie, saying that no matter who won part 3 they would take each other regardless and boot Spencer.

GinaMarie also made a deal with Spencer, with the pair agreeing that neither of them could beat Andy in a final 2 scenario. No matter who wins the final HOH competition, there will be one houseguest who is bound to be disappointed.

The season finale of Big Brother airs on Wednesday at 9:30 p.m. on CBS, featuring the final HOH competition, the final eviction and the jury voting to crown the winner.
