An idea that can be discussed:

Lottery

Loritta's lottery is just one more addition to its economy that'll be very similar to the +riffle command, the way the clusters're going to communicate and manage winners will have the exact same design.

Ticket

One ticket must contain 6 numbers between 1 and 20, and they'll cost 10,000 sonhos (variable value).

Awards

The award is 33% of the ticket's income with a pseudo-random initial value and will be distributed following these rules:

• 50% for people who got 6 numbers right ("sena");
• 30% for people who got 5 numbers right ("quina");
• 15% for people who got 4 numbers right ("quadra");
• 5% lottery taxes;

Abstention

The abstention will occur when there's no "sena" winners, even if someone won the "quina" or "quadra", this event adds the current lottery's total award to the next one.

Schedule

Every day at 08:00PM, the lottery's result will be released and another one will be started.

If this looks good, I'll start a pull request implementing these ideas.

[SrGaabriel]

I will change to make 6 being the maximum and minimum value to a ticket, this would be better in my opinion.

[SrGaabriel]

The max number of tickets that someone can buy will be 4 (open for suggestions)

[SrGaabriel]

They can cost 10k sonhos because the chance of winning is currently high, and we need a higher income to increase the prize.
