After you collect enough medals, you can return to Warehouse Freightman Cliff (or WH Cheif) to play bingo. Rules of game: you are allowed to choose 6 numbers from 1 to 9. After your choise all 9 numbers are randomly being distributed in 3x3 square just like that:

The goal is to get 3 lines in the square with numbers you have chosen. For example, the combination 2,3,4,6,7,9 make you win the game.
