Roulette Master! app is an evolution of my Roulette Wiz! app. Some advanced users requested some new systems, and Roulette Master! is here for that: to allow you building your own systems. Roulette Master! has a powerful alarm manager that eases the visualization of active systems. Roulette Master! is an application that assists you in targeting sleepers (looks for roulette bets that don’t appear for a long number of spins). The app allows defining a general alert threshold that is customized for each kind of bet. Every time that a particular threshold is exceeded, Roulette Master! alerts the user, indicating that is a good time to start betting. Bets that are available in this version are: - Red-Black - Even-Odd - Low – High - Dozens - Columns - Lines - Streets - Numbers - Voisins du zero This application is intended for use in online games. Its use in real casinos may not be authorized.
