"Love Island" has officially taken over the summer since a U.S. version of the U.K phenomenon began airing in early July. Now, practically half-way through, the contestants must continue to use their heads, hearts, or both, to make it through to the end of the season, where viewers will ultimately decide who will be crowned the "Love Island" champions and win the grand prize. 

What's the grand prize?

Well, it's a lofty $100,000, but how that gets broken up is where things can get tricky. Although it is technically a couple that wins, one half of said couple could choose to steal all the money for themselves, leaving their partner with absolutely nothing. 

"Love Island" is the American take on the British dating reality show of the same name. The CBS series involves a group of contestants, referred to as Islanders, in a villa in Fiji living under constant surveillance and in isolation from the outside world. The Islanders have to couple up,  either in romantic, strategic or friendship-based alliances to avoid elimination as they work towards the grand prize. 

The U.S. version of the international hit started with a cast of 11 singles, but as the show progresses dynamics have shifted with the arrival of new Islanders, as well as some eliminations which have already taken place.

Hosted by Arielle Vandenberg, fans can vote for their favorites and catch all the "Love Island" drama weeknights on CBS at 8 pm ET.
