The balance is used to fund projects in Ireland in the areas of health, sport, recreation, arts, culture and national heritage, including the Irish language. A seventh number is also drawn and is called the 'bonus' number. Prizes can also be won by matching five numbers, five numbers plus the bonus number, four numbers, four numbers plus the bonus number or three numbers plus the bonus number. Although people tend to pick their own lucky numbers, a 'quick pick' option is available which instructs the Lotto computer to select the entry numbers.
Prizes are tax-free and are paid out in one lump sum.
