I started watching The Big Bang Theory, and while watching the earlier episodes, I saw the one in which Sheldon created an updated version of Rock, Paper, Scissors: Rock, Paper, Scissors, Lizard, Spock.
This is a very simple business which works mainly with one website. It's basically a game that where you can have people play in three different modes: Beginner, Advanced, and Chuck Norris (you will lost probably 99% of the time). In order to advance to the higher modes, you must win a certain amount of games (either in a row or total).
Here are the rules of wins and losses:
Scissors cuts Paper
Paper covers Rock
Rock crushes Lizard
Lizard poisons Spock
Spock smashes scissors
Scissors decapitates Lizard
Lizard eats Paper
Paper disproves Spock
Spock vaporizes Rock
Rock crushes Scissors
After playing each game, it will save the player's choice in a database to help with the Advanced mode. You will need to sign up for an account (mainly with email address) in order progress to the higher modes because it will use more specific information from your choices in order to guess what you will choose.
The beginner mode will save the choices of everyone, and will make an educated guess as to which choice you will make (based on choice totals for everyone who has played the game, which are all saved on the database). The advanced mode will base it off of the specified choices you have made, which will make it more difficult (it will add the ones that everyone makes as well, but it will weigh your choices more than those of everyone else. As you play the game more and more, it will make more and more accurate choices as to which you will choose and habits, like order or choices, etc). As for the Chuck Norris mode, it will see what you have chosen and will use an algorithm which will basically choose two random numbers out of 1000 (can be the same number), and if the numbers are the same, it is a win for the player, if not, then the next game will choose one more number (2 potential winning numbers (mutually exclusive) for the player, one to see if it matches the potential winners (not mutually exclusive)). As long as there are no wins for the player, it will add one more potential winning number for the player. As soon as the player wins, it will reset to only choosing two numbers.
Well, that is it. It's a pretty simple game that can be very fun and you can get some email information to use to sell them other things or sell to another company, or whatever you want to do with them.
