I am actually having the same issue as this.
Over in the UK on their lotto website is http://www.national-lottery.co.uk/player/p/home.ftl
and you can officially play euromillions on it however it states to UK residents only. :-(
I dont see how Ireland are sooooo far behind the times and cant update http://www.lotto.ie/
website with the same credentials as the uk so we can play online here.
There are websites you can play lotto and euromillions online with:
Problem with these is a line costs about 70% per line than your regular €2.00 line, so about 3.60 a line each, and the currency is usually different i.e. GDP or USD.
Other turn down i can see is that even though you can use your credit card to pay, you cant use Paypal(to Hide your credit card details). I can see this being a drawdown for ppl ho dont like giving their CC details out.
Hope this helps Guys and Gals
