Roulette

This application allows two or more players to play the standard French Roulette game.

Two different views allow to make your bets, to launch and view the white ball rolling up to its destination cell, and to see your wins and losses.

When you launch the application for the first time, you are prompted to define the number of players (including the guy who will keep the bank), and name and initial amount of money owed to each of them. When you re-launch the application the next time(s), you can re-define all these data, or, optionally, restart with the same players and the same cash status as at the end of the last game.

The money unit is called 'credit', and you can interpret it as you local money unit: euro, dollar, pound, franc, and so on.

The main view shows the green cloth of a standard french roulette board, a selector to choose the player doing bets, and a set of coins, representing the total available amount of the selected player. Every player has coins of a different color. When you change player, the coins are shown with the owner's proper color. This feature allows you to distinguish your bets from the bets of other players.

To make a bet, just draw a coin to the position where you want to put you bet.
Every player can make one or more bets. Then, another player can select his name, and make his bets.

You can bet on a single number, or on the border between two numbers, or on three, or four, or six numbers.
Or, if you prefer, you can bet on a column, like 1 to 34, or on a group of 12 numbers: P (Premier 1-12), M (Moyen 13-24), D (Dernier 25-36).
Or you can bet on a 18 number group, like Manque (1-18), Passe (19-36), Pair (even), Impair (odd), Noir (black) or Rouge (red).

Remember that, in case of success, the price for every successful bet depends on the range of numbers covered by that bat, and more precisely:

Single number:wins 35+1 = 36 times the bet value
Two numbers:win 17+1 = 18
Three numbers:win 11+1 = 12
Four numbers:win 8+1 = 9
Six numbers:win 5+1 = 6
12 numbers:win 2+1 = 3
18 numberswin 1+1 = 2

For example, if you bet 10 credits on a couple of numbers (11 and 12), and 11 wins,
you will get your 10 credits back + 170, for a total of 180 credits.

Notice than the number 0 does not belong to any group (Manque, Passe, Pair, Impair, Rouge, Noir, Premier, Moyen, Dernier, columns). So, when the 0 exits, all the bets are losers, except eventual bets made just on the number 0.

When all players have done with betting, just tap the 'Launch the ball' button.
The roulette wheel will then be shown, and the white ball will be launched.
After some seconds the ball will stop on a number.

On the right side of the wheel the result will be shown: number, color (rouge or noir), parity (pair or impair), half of the table (manque or pass) and dozen (premiere, moyen or dernier).

And the result for each player will also be shown, indicating the wins (if any), the losts, and the residual money in cash.

Having examined the result, you can hit the 'New game' button to restart a new game.
