shuffle randomly permutes the specified list using a default source of randomness, and has no return.

Try to change this: 

 gamers = Collections.shuffle(gamers);

With:

Collections.shuffle(gamers);

change

gamers = Collections.shuffle(gamers);

to

Collections.shuffle(gamers);

shuffle mutates the passed List instance and has no return value.

Change

gamers = Collections.shuffle(gamers);

to

Collections.shuffle(gamers);

The static shuffle method of the Collections class has a void return type.
