Came across a new website called
which according to it’s tag is “Ireland’s only Gaelic Games fantasy game that gives you the chance to win thousands of euros in prizes”.
Uses both hurling and football, after you register each week you pick what you think will be the outcome of all the weekends matches and you get points based on correct selections.
I don’t know of any other GAA based fantasy games out there so if you haven’t already done go ahead and give it a go at
