Move the coloured coins so they are above the appropriately coloured piggy banks. To rearrange two coins, simply touch them one at a time. To bank the coins, you will need to touch the piggy banks below, but remember, you will need at least 2 colours at the bottom of the row. The higher you stack the columns, the more money you will make when you bank. Don't get too greedy or you will run out of room. If one of your columns is getting too high, use a hammer to smash the piggy bank and clear the entire column. To use a hammer, simply touch the hammer icon followed by the piggy bank you would like to smash.
