A lottery game definition is the description of a particular lottery game: it defines how a valid ticket looks like.
E.g. a EuroJackpot ticket consists of two sets of numbers:
- 5 numbers from the [1–50] interval,
- 2 numbers from the [1–10] interval.
This can be configured as follows:
{
// …
"lottery_game_definitions": [
{
"game_name": "EuroJackpot",
"drawing_sets": [
{
"n": 5,
"min": 1,
"max": 50
},
{
"n": 2,
"min": 1,
"max": 10
}
]
}
]
// …
}A lottery ticket pack is a set of played lottery tickets sent to one or more email addresses. E.g. if you play 1 ticket of EuroJackpot and 1 ticket of Lottery 5, and your brother plays 1 ticket of Lottery 5 and 2 tickets of Lottery 6 each week, you define two separate lottery ticket packs, which will be sent to you and your brother separately. You can also configure permanent tickets with regularly played numbers. Permanent tickets must conform to the game definition, and cannot contain duplicate numbers.
Lottery ticket packs can be configured as follows:
{
// …

{
"email_to": [
{
"email": "[email protected]",
"name": "Your Name"
}
