1)Try to move the homing mines as close together as possible. This makes them not take up as much space and make it easier to get dubloons.
2)Try to make sure you have as many homing mines as possible and that they don't crash in to each other. If you have many homing mines, no more will appear making the game much easier.
3)Disable all graphic options before you start playing Dubloon Disaster.
4)Circle the set of homing mines to get them closer together.
5)When a dubloon is close to a homing mine, attempt to move all homing mines in to a corner away from the dubloon and then get the dubloon.
6)When a dubloon is close to a homing mine, touch the dubloon from the outside edge.
7)When you are close to a homing mine, do not turn. Move in a straight line because turning slows you down.
