[edit] Drawings
Drawings happen twice a week, on Wednesdays and Saturdays. The drawings consist of picking globes from 2 spinning spherical cages. They are picked in pairs, in order to form a 2 digit decimal number from 01 to 60. The first cage has balls ranging from 0 to 5 for the first digit, and the other one has balls ranging from 0 to 9 to be used in the second digit. In the event of the number 00 showing up, it will be replaced by the number 60 for prize purposes. When 6 unique 2 digit numbers are drawn, the drawing is concluded.
[edit] Betting
Betting instructions and information are present on the back of the betting ticket. Contestants may bet in the range of 6 to 15 numbers, out of 60, and scoring 4, 5 or 6 points will grant prizes. Bet prices escalate depending on how many possible groups of 6 numbers exist within the numbers chosen, so they vary between R$2.00 for 6 numbers (only 1 game possible) to R$10,010.00 for 15 numbers (5005 games possible). The chances of winning the biggest prize when placing a minimum bet are 1 in 50,063,860.
[edit] Prizes
Raw prizes correspond to 46% of raw income from bets. Out of this figure:
- 35% will go to people who scored 6 numbers.
- 19% will go to people who scored 5 numbers.
- 19% will go to people who scored 4 numbers.
- 22% will accumulate for a special drawing occurring once every 5 times.
- 5% will accumulate for a special drawing occurring at the end of the year.
- Income Tax will deduct 13.8% from all the previous items. The net value for prizes is actually 32.2% of lottery earnings.
Winners have 90 days to withdraw their prizes. Prizes below R$800 can be claimed at a lottery house. Prizes above R$800 must be claimed at the Caixa Econômica Federal bank. If the 90 day period expires, prize money is transferred to the national treasury and invested in educational programs.
[edit] Income redistribution
The other 54% of lottery income is spent on costs and then redistributed to several social programmes.
