Such a skill set would involve years of training, an extraordinary memory and numeracy, and/or acute visual or even aural observation, as in the case of wheel clocking in Roulette.
The Eudaemonic Pie is a 1985 book by American author Thomas A. Bass, about a group of University of California, Santa Cruz, physics graduate students (known as the Eudaemons) who in the late 1970s and early 1980s designed and employed miniaturized computers, hidden in specially modified platform soled shoes, to help predict the outcome of casino roulette games.
The Eudaemons were a small group headed by graduate physics students Doyne Farmer and Norman Packard at the University of California, Santa Cruz in the late 1970s.
