The Oracle is a new tool that allows, on the basis of a mathematical model based on actuarial techniques, to determine the probability of occurrence of a particular event in a tennis match. Variables which forecasts are as follows: winner of the match, exact results (in the form of sets, or rather, 2-0, 2-1, etc.), score with a handicap and existence of tie-break.

It is a tool of great utility for any tennis gambler, even more considering that the accuracy of the model is approximately 98%. Gamblers only have to seek odds in which betting house deem less probability that the model gives and bet on them (that is called value odd) with which the benefits in the medium and long term are guaranteed.
