On September 3rd 2015, the National Lottery increased the number of balls in the draw from 45 to 47. The odds of winning one of the various prizes in the Irish Lotto based off of 47 numbers is below. The odds of winning under the "old" 45-ball game are here. Minimum prize amounts in the Main Lotto draw don't seem to be guaranteed. They have a formula for working them out, and can change each draw, so please keep in mind the prizes listed below are not guaranteed - they are taken from the official National Lottery literature which was distributed to newsagents prior to the launch of the new game. Combination Odds Prize Money* 6 Numbers Jackpot 10,737,573 / 1 €2,000,000 5 Numbers and Bonus 1,789,595 / 1 €100,000 5 Numbers 44,740 / 1 €1,500 4 Numbers and Bonus 17,896 / 1 €150 4 Numbers 918 / 1 €50 3 Numbers and Bonus 688 / 1 €25 3 Numbers 54 / 1 €9 2 Numbers and Bonus 72 / 1 €3 Scrathcard * Prize Money is not a guaranteed amount. One way to look at the above is that if the National Lottery Lotto draw was fair, then considering you pay €2 per line, the jackpot should be a minimum of over €21m every time! So you could look at it like the National Lottery is only giving you 9% of what you should be getting, if you win a jackpot of €2m. I know many Charities in ireland avail from the lotto but it seems you have a better chance of getting knock down by an airplane crossing the street then you have of winning the lotto.
