At least 50% of the sales of all National Lottery tickets and scratch cards must be allocated for prizes each year. The percentage allocated will vary from game to game and can be found in the individual game rules.
Detailed information about each National Lottery game is available at www.lottery.ie. The odds of winning the top prize in each game along with a detailed breakdown of the prize money for each prize tier in a game is available in the game rules.
The prizes paid out each year in any game will depend on the prizes actually won and claimed.
