Working from his San Francisco shop, Fey kept his cool invention to himself, not selling the make rights to big companies.

- Five different signs
- Machine that gives coins
- Heavy metal build
- Single line for winning
This big start set the ground for today’s slot machine builds, starting a new age of gambling fun.
