Some ideas:
1. It will need a little polishing since Multibit and Mt.Gox are ... part of the history.
2. It
could be an idea for advertising to make it work with testnet coins.
3. It could be an idea to make it work on LN with much smaller amounts. Some may play it simply because it's on LN.
Of curse, for #2 and #3 you should lower the required funds (and the prize) and maybe show a progress (how many tickets are needed) until the next draw.
Did that here no one played, freebitcoin pretty much so has the lottery aspect on lock , however if someone deploys a LN micro lotto id be down. @op you need more information really. that games called blockchain lottery BTW, (16 players (0-f) call out a block and last digit of TXID that's hashed for that block.
I tried this with google sheets and 1000 satoshi, even loycev and other major supporters of LN didn't want to risk 1000 sats or care to anyways. Im learning almost all development on LN really is #reckless and nothing really gets followed up on. I used to be a really big supporter on LN and its concepts but it doesn't get the attention it deserves so I opted out and closed all nodes/channels.
