The cube owes its name to the location where the game takes place: a huge, transparent cube full of high-tech gadgets and nerve-racking games. Every week, seven candidate pairs compete against each other and the complex challenges that vary from blindfolded assignments, balance tests and obstacle courses. With every game won, money is earned that can amount to 100,000 euros after seven rounds. The candidates can decide to quit after each round and then go home with the money won. If they continue to play, they risk everything. They do get nine 'lives' each. When they run out, the adventure ends and they lose all their money.
