You can use this JavaScript. Its still semi-manual but speeds things up a bit. Works on Chromium-Based browsers for sure. You might need to change the sleep delay. 6000ms = 6sek worked for me.

function sleep(ms) {
    return new Promise(resolve => setTimeout(resolve, ms));
}
$("button[value=claim]").each(function(){
    $element = $(this);
    $.post( location.href, {
        csrf_token: $element.siblings("[name=csrf_token]")[0].value,
        game_id: $element.siblings("[name=game_id]")[0].value,
        action: "claim"
    })
});
await sleep(5000);
$("a.next_page")[0].click()
