The checkin feature is at the heart of the All Square experience.
It allows you to notify your friends when you are golfing but also keeps track of all the courses you have played. Each check-in (and review) drops a pin on your World Map!
During the month of May, you need to check-in (with the mobile app) at 3 different golf courses to get an entry to the prize draw for one Saturday or Sunday VIP ticket to the BMW International Open (21-24 June 2018) at Golf Club Gut Lärchenhof in Cologne, Germany.
Enjoy your golf and best of luck.
