### Stop or Dare

All you need for this game is a pack of cards. While you play the game, think about strategies that will increase your chances of winning.

### Snail Trails

This is a game for two players. You will need some small-square grid paper, a die and two felt-tip pens or highlighters. Players take turns to roll the die, then move that number of squares in a straight line. Move only vertically (up/down) or horizontally (across), never diagonally. You can cross over the other player's trails. You can trace over the top of the other player's trails. You can cross over a single trail of your own, but can never cross a pair of your trails (side-by-side) or trace over your own trail. To win, you must roll the exact number needed to finish in the target square. You can never pass through the target square. The game ends when a player ends his/her trail in the target square, OR when a player cannot move without breaking any of the rules.

# Odds and Evens

##### Stage: 3 Challenge Level:

You could start by using the interactivity - what happens when you pick out two balls from set $A$ $100$ times?
How many times did you get an even total? Were you expecting this?

Work out all the possible combinations for set $A$, to see if you can make sense of what happened.
How will you make sure you don't miss any combinations out?
