The overall design of this app is geared towards Alain Nu's 'Serial Thrillers' plot as described in Alain Nu, 'Serial Thrillers', Alain Nu 2009. The app cycles through 'Serial Thrillers'' logical phases and serves as a virtual spectator who whispers random digits. It allows you to validate your conclusions against the correct response before taking you right into the next cycle.

Some Features: - serial numbers up to 26 digt length - The design is kept straightforward and simple and fully tailored to help you focus on the real work. Practicing magic you don't want no complicated, overloaded and distracting user interface. Less is more. yeahgic.com dedicates to card magic apps since 2010. Its other commercial apps address the ACAAN plot, the Twice as Hard plot, Stack Training, and - probably the most courageous app in card magic academy - the Symbolic Method editor. - Note: the app's design is limited to ascii-font without any pictures. No buttons - it responds to gestures only. The help text is spartanic without formatting. It has the minimum design required to achieve its purpose.
