Laravel - Where relationship column equals?

I am trying to grab all records where Player's relationship called stats() has a column value of something. I would usually do ::where('column_name' 'column_value') for the players table, but how can I get ::where the relationship table's column equals to something?

Player::where('column_name', 'column_value')->get();

But I want to check a column in the relationships table?

public function roleplay()
{
    return $this->hasOne('App\Database\Frontend\User\Roleplay', 'user_id', 'id');
}
