Good day
please tell me the solution
There is a custom post type “Games”
There is a filter by the number of possible players in this game
In the “Game” itself, the number of players is indicated in the form of an arbitrary field ACF Checkbox
to 1 to 8 and returns an array accordingly
Filtering happens through AJAX
man indicates count. players and you need to load the game in which one of the values

Here is the code for the upload function
please tell me what should be specified in meta_query for such filtering

    $args = [
    'post_type' => $_POST['postType'],
    'orderby' => 'menu_order',
    'order' => 'ASC',
    'paged' => get_query_var( 'paged' ),
];

if( isset( $_POST['playerID'] )) {
    
    $playerID = $_POST['playerID'];

    if ( $playerID == 'all' ) {
        $args['meta_query'] = [[]];
    } else {
        $args['meta_query'] = [
            'relation' => 'OR',
            [
                'key' => 'g__players',
                'value' => $playerID,
                'compare' => 'IN'
            ],
        ];
    }
}

$query = new WP_Query( $args );
