I watched the videos for the electronic devices that predict what roulette numbers will come up (or their neighbors on the wheel). I just have one question. How are these devices profitable if most, if not all casinos (online), require that you place your bets before the roulette wheel is spun? If this has already been discussed as to how to overcome this little obstacle, please refer me to the thread. Thanks

Hi Bam,

Unfortunately roulette computers can not predict outcomes when the bets are called off before ball release.
