The Addiction Machine is a documentary that explains how engineers, mathematicians and scientists working with music composers and designers create devices that are designed to do one thing - to keep you losing your money to them.
It also shows how these machines work on your brain, and the stories of those who have fallen prey to these hypnotic devices.
This documentary is set in Australia and the United States, but the issues raised also apply here to pokie machines currently used in New Zealand.
Right now the documentary is free to watch on demand via TVNZ+, the online on demand service (conditions apply)
