Add this single line in your server's crontab (runs every minute; the script itself decides what's due):
* * * * * /usr/bin/php /home/u631271575/domains/luckeyzet.casino/public_html/bot/cron_runner.php >> /home/u631271575/domains/luckeyzet.casino/public_html/bot/cron.log 2>&1
Edit with crontab -e. Adjust the PHP path if which php gives something different than /usr/bin/php.
No schedules yet. Add one above.
