Symfony3 Trying to add record in join table - php

Question

A User has many Games.
A Game can Belong to many Users.
I have a form with a list of games, I want the list of Games to be added to the current logged User.
When I submit the form nothing happens, I want at least 1 record to be added to users_games:
Update:
Added User entity
FormType addGameToUserType:
namespace AppBundle\Form;

{
$builder->add('game', EntityType::class, [
'class' => 'AppBundle:Game',
'choice_label' => function ($game) {
return $game->getName();
},
'multiple' => true,
'expanded' => false,
]);
}
