how to run a lottery pool
To run a lottery pool, decide how many tickets the group wants, split the cost into shares and write everything down before anyone pays. The same method works for Powerball, Mega Millions or Brazil's Mega da Virada, the New Year draw of the Mega-Sena lottery. The calculator below opens with the Mega da Virada setup, and you can switch to any other game in one tap.
Each pays BRL 6.00, the price of one simple ticket.
BRL 60.00 over 8 is BRL 7.50, with nothing left over.
One person pays one cent more; the total is exactly BRL 60.00.
Covers 28 combinations of 6 numbers; split by 6 people, BRL 28.00 each.
Ten times the 1 in 50,063,860 chance of a single simple ticket.
Divide the total cost by the number of shares. Five Powerball tickets at $2 cost $10; split in 4 equal shares, each is $2.50. When the division does not come out even, such as $10 in 3 shares ($3.3333...), the calculator works in cents: 1,000 cents divided by 3 is 333 each with 1 left over, so one person pays $3.34 and two pay $3.33, adding up to exactly $10.00.
As many as the group can pay for without strain. Work out the budget, divide it by the ticket price and round down. Each added ticket raises the group's chance by the same amount, so doubling the tickets doubles the chance and also doubles the cost.
One trusted person named in writing, who photographs the ticket and sends the picture to everyone right away. A paper receipt can get lost, so the photo and the agreement are the group's proof. The contract the tool writes has a field for the name.
Among friends, yes, but the calculator uses the same count of numbers on every ticket to keep the math clear. Official pools such as Brazil's Bolão Caixa are described by the press as requiring the same count on every bet. If your group mixes sizes, run one pool per ticket size.
It is not required, but it prevents the most common fight: someone swears they paid when they did not. A short agreement with names, shares, amounts and a deadline settles it. The Contract tab writes the text, and the SHA-256 fingerprint shows whether it was changed later.
