Debt blocks will fall from the top of the screen. You need to destroy the debt blocks by making them contact with the money blocks of the same colour. There are a limited number of money blocks, so you need to put the debt blocks of the same colour together (i.e. consolidate the loans) so that they can be destroyed by one money block. There are credit card blocks that will generate new debts for every 3 rounds, so try to cut the cards first. Use the arrow keys to move the blocks and press the Up and Down keys to rotate the blocks, press the Spacebar to drop the blocks.
