The National Lottery is to implement changes to the games and dates for the Lotto from Saturday 5th September. This will slightly improve the odds of winning across every prize tier in Lotto, Lotto Plus 1 and Lotto Plus 2. The Lotto Plus 2 top prize will increase from €250,000 to €1 million while the Lotto Plus 1 top prize will remain at €1 million. There are no changes to the price to play either Lotto or the Lotto Plus games. The National Lottery was established by the State in 1987 to raise funds for good causes.
