This is a simulator for finding shiny Pokémon. Click or press the space bar to simulate one wild encounter. If you somehow manage to get a shiny Mewtwo, the total will go up by one (this is a Global variable, it is the same for everyone). In the games from the Pokémon series, it is possible to encounter a shiny Pokémon in wild battles. This changes the color a of the Pokémon and makes it sparkle. They are incredibly rare, with a 1 out of 8192 chance of finding one at any given encounter. Good luck, and happy shiny hunting! http://bulbapedia.bulbagarden.net/wiki/Shiny_Pok%C3%A9mon
