In due time you'll be playing for SATs

Kinda surprised there isn't a simple wallet which let's a user put in say 1k sats to another wallet, with 5 other users doing the same. Which the 'winner' gets the total 5,000 sats, pkue their original 1,000 SATs back in a LNURLw link

Hmmm.... I think I can make this actually...

Would you use this?
