Non native English speakers often have trouble in distinguishing between 15 and 50. Luckily, there is no 50 pocket on the roulette wheel, so you won’t get caught out by that one if you are calling out a special bet at the table, such as “Complete Bet on 15 please!”
15 is the 5th triangular number (after 1, 3, 6 and 10). The easiest way to explain this is that it is the amount of balls you can stack together ( a bit like when you rack up snooker balls or pool balls at the beginning of a game) to make an equilateral triangle.

The Magic Square is well known in many cultures. According to legend, it was discovered in 2205 BC when a Chinese Emperor found a magic square on the back of a turtle.
In a magic square, numbers starting with 1 are arranged such that if you add any of the numbers up horizontally, vertically or diagonally, they all come to the same number. In the case of the 3×3 square to the left, the magic number is 15. (Hey, and we thought 3 was the Magic Number!)
Across Asia the 3×3 magic square is called Lo Shu (after the legend of Lo Shu) – you´ll see it being used quite a bit in feng-shui. So, as you can imagine, along with 8, 15 is seen as a pretty lucky number in China. Not every number has legends associated with it.
It´s also pretty big in India, and across the Middle East.
In Europe, magic squares ( from 3x3s to 9x9s, were assigned to planets, and were thought to be able to bring in the influence of the planets and their angels (or demons) during magic. The 3×3 square associated with the number 15 was assigned to Saturn.

The 4×4 magic square sums to 34- another number on the roulette wheel.

How to Bet on the Number 15 in Roulette
Well, you can just go ahead and make a single number bet on 15 of course, but that´s pretty risky (unless you plan to stick around the table for a long time). The number 15 also site in the second dozen and the top column if you prefer to cover at least 1/3 of the table. Or make an even money bet on black, odd or the low numbers (you can combine these in some systems such as the One Column and Black strategy.
Or go ahead and cover the number on an inside bet like a corner bet, a street bet, a split bet or a 6 line bet.
You can also cover 15 with some of the special bets like the 007 bet, the Jeu Zero and the Voisins du Zero bets, Or place a Finales en Plein 5 which will cover 5, 15, 25 and 35 with individual bets. A Finales en Cheval 5,8 also covers it, but this involves split bets rather than straight up bets, as you are covering 2 sets of numbers.
