In kettle peeking, the Roulette Player tries to predict with a "nimble eye" where the ball will fall. A roulette player who has mastered kettle peeking can predict the likely impact sector of the ball by matching the speed of the ball with the speed of the roulette cylinder. Accordingly, kettle peeking is based on the physical characteristics of the roulette wheel.
The difficulty here is that the "kettle gazer" must make his Bet within a few seconds of the ball already being in the kettle. From the moment the Croupier says the famous words "Rien ne va plus", i.e. "Nothing works anymore", no more bets can be made.
Bets on adjacent numbers in the kettle are particularly popular with players who practice kettle watching professionally. For example, players can bet not only on a specific number, but also on a specific number as well as its two, three or even four numbers adjacent to each other. In this way, the chances of success in kettle watching can be optimized.
The calculation of the impact sector depends on several different variables. Of course, these cannot be predicted completely reliably even by experienced "kettle peepers", so there is still a Risk of loss. Besides the speed of the roulette wheel, the weight or the nature of the ball is also decisive. Those who practice kettle watching over a longer period of time also have the possibility to discover kettle errors and use them for their own benefit
In the past, kettle watching was made more and more difficult by the casinos. To this end, for example, the "old" balls have been replaced by faster Teflon balls, and the overall speed of the cylinders has also increased. It is also worth mentioning that the international community of professional "kettle peepers" comprises only a low double-digit number of players.
