Christmas is coming so why not design a game to get into the holiday mood. This is a game inspired by the 12 days of Christmas, it allows the player and the computer take turns to choose their gifts from the list.
Each player types a number to pick a gift from the 12 items above, so you need to keep two lists.
But Santa only grants three gifts for each player, so you take away half of each list randomly so no one knows what are left.
Wrap each gift and display on the screen. So you should display 6 wrapped gifts on the screen. Three on one side for the player, three on the other side for the computer.
Display a die in the middle. If the die is clicked, it either says switch, steal or unwrap. The player and the computer take turns to roll the die until all gifts are unwrapped. (To do this, you will need a random number between 1-3 to simulate the die. You also need to update the gift lists after each switch, steal or unwrap.)
The game ends when all gifts are unwrapped, then you should display: on the 12th day of Christmas, your true love will send you XXX (whatever the player got)
