“Roulette”
Roulette is a casino and gambling game named after the French word meaning "small wheel". In the game, players may choose to place bets on either a number, a range of numbers, the color red or black, or whether the number is odd or even. To determine the winning number and color, a croupier spins a wheel in one direction, then spins a ball in the opposite direction around a tilted circular track running around the circumference of the wheel. The ball eventually loses momentum and falls on to the wheel and into one of 37 (in European roulette) or 38 (in American roulette) colored and numbered pockets on the wheel.
The cache is a large Lock-n-Lock containing "number pockets". The log book is in one of the "number pockets". Keep betting until you win, luck will determine how long you will be at the table.
In your log it would be fun if you entered your winning bet and the number of tries it took. For example: 34R/5, meaning number pocket 34 Red and 5 tries. After you sign the log, place it in a new "number pocket" for the next cacher.
