In his 'Last Will', your rich uncle stated that all of his millions will go to the nephew who can enjoy money the most.
How to find out which nephew should be rich? You will each be given a large amount of money and whoever can spend it first will be the rightful heir. Visit the most exclusive theatres or eat in the most expensive restaurants. Buy old properties for the price of new ones and sell them as ruins. Host a huge party in your mansion or on your private boat.
Spend like your life would depend on it. Spend to become rich! If you're the first to run through the money on hand, you'll receive the rest of his inheritance – oh, and win the game!
