Hacker finds the Krystal of Kalamoor, the powerful orb that will give him eternal power. By possessing the Krystal, Hacker can roam cyberspace and create havoc without having to recharge his power. When the kids and Digit arrive to retrieve the Krystal, they are stymied by a series of switches, levers and buttons. Faced with the challenge of too many choices, the kids discover the value of lists, tables and, yes, tree diagrams!

Harry Does Lunch
Harry has a new job in a deli, but he has to figure out how to bring in more customers or he'll lose it! He starts thinking about all the ways he can combine what's in the sandwiches, and bingo -- he gets 120 different kinds, and business is booming!
Math Message: Organized lists can help you master combinations. To find the number of possibilities, multiply together the number of possible choices for each category.

Disquise Combos
In this game, the Cybersquad uses disguises to fool Hacker. The player helps by creating as many combinations of wigs, glasses, and beards as possible. As the game progresses the relationship between multiplication and combinations is revealed (i.e. if you have 3 wigs and 2 pairs of glasses, you can make a total of 6 combinations.)
