Purchases/lotteries/whatever allow one entry per natural person, using an ID. You have to indicate ownership of that ID to take up the entry ticket. Then you have to show the ID on entry. Typically such places will buy back tickets and you get a refund if they sell.
You can use 'receipt of state assistance' (in the UK this is called 'benefits') as a marker for poverty [definitely not perfect!] and only allow access to, for example, a low cost lottery on entry for such poor people.

It's not perfect, but is that not at least good?
