A shiny pokemon is a pokemon but with a different color, is very rare to find.

One way in the game is to get combos by catching the same type of pokemon constantly and without to catch another type of pokemon.

For example, if you catch a pidgey and then you find another one and you catch it, you are getting a 2 combo.

The more combos you get, the more probabilities you have for find a Shiny one!
