You have to assembly coins and bill notes in order to increase their values and reduce their number: the goal is staying alive. You can only move coins and bill notes against a side of the grid then you can assembly coins and bill notes: 5 replaces two of 2 and one of 1, 10 replaces two of 5 or five of 2, 20 replaces two of 10 and so on.
