I did a quick grabber to claim them all using JS, but you need to run it from the console on each page of the bundle. I tried to make it get them all but it's throwing too many errors and I cba to fix it, this is quicker than doing it for them all individually anyway! Note that it will throw errors because of CORs but the games will appear in your library, once it stops throwing errors move to the next page!
baseURL = window.location.protocol + "//" + window.location.host + location.pathname
var games = document.getElementsByClassName("form");
for(var x = 0; x < games.length; x++)
{
var csrf_token = games[x].getElementsByTagName("input")[0].value;
var game_id = games[x].getElementsByTagName("input")[1].value;
var xhr = new XMLHttpRequest();
xhr.open("POST", baseURL, true);
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhr.send("csrf_token=" + csrf_token + "&game_id=" + game_id + "&action=claim");
}
