Six from 47
The Irish Lotto format here is six numbers from 1 to 47, with no second pool. Six from 47 can be chosen in 10,737,573 ways, and a single ticket holds exactly one of them: 1 in 10,737,573. Those are the shortest jackpot odds of any game on our list.
Two balls make a real difference at this size. A six-from-49 game has 13,983,816 combinations, 30% more than six from 47. The table shows how quickly the count grows as the range widens, for the six-number games that have their own page.

Neighbors and dates
With six numbers packed into 47, consecutive pairs are more common than not: 51.1% of random lines contain at least one, such as 8 and 9. Hand-picked lines that avoid neighbors to look random are, in that sense, the unusual ones.
Picking at random does not improve on 1 in 10,737,573; nothing does. It matters only for sharing. Of the 47 numbers, 16 (32 to 47) cannot be a day of the month, so a line of birthdays never uses them, and neither do the many other date-based lines. A random Irish Lotto line stays within 1 to 31 6.9% of the time.
For scale, a random line shares at least one number with the six drawn 58.1% of the time, and exactly three 2.0% of the time. Each extra match is far rarer than the one before, which is how the count reaches 10,737,573 for all six.

Where the randomness comes from
This tool runs entirely in your browser, using its built in cryptographic random number generator. Nothing you type is sent to us, nothing is stored, and each result is thrown away the moment you leave the page. Numbers are drawn without the rounding bias that the usual shortcut introduces, so every outcome is as likely as every other.
Because nothing is recorded, a result here proves nothing to anyone afterwards. If you need a drawing that other people have to accept, for a prize, a campaign or an audit, use Winner Picker, which publishes each result on a permanent link with a signed record anyone can check.
