Is there an automated way to buy tickets (online, or whatever)?

A startup could hire someone to buy tickets all day, but that would get tedious...

I think I just understood that the official outlet for lottery tickets physical stores. Is that really so? As a European I am kind of baffled by this, as we (at least in my country) have had an official app for buying tickets for the state lottery and sports betting for ages.

What is the reason for that? Do the players only trust hard physical paper numbers?

Btw, the euro jackpot is about €120m, but still far from profitable.

You can "subscribe" on at least the IL Lottery site to "auto buy" tickets.

There's been a number of instances where people did precisely that--they just sent a bunch of taskrabbits out to buy large numbers of tickets in lots of different locations. Very time-consuming, but still profitable.

there's an app called JackPocket

Yeah there is a startup that does this, they buy lotto tickets for you in app for a fee.
