It works on regtest. You can get lots of signet coins using this faucet:

it works on the "bitcoin inquisition" regtest but not the "bitcoin" regtest
and I don't want to make my users do this procedure to use my playground:
(1) download and set up bitcoin inquisition
(2) download and set up and run powcoins
It's just too much
1. Downloading inquisition is same as downloading core if using regtest.
2. You can get hundreds of coins using this faucet and provide small amounts in the playground for users.
1. It feels a bit different to me, but anyway telling my users to download *anything* (even bitcoin core) is too much
2. That sounds like the same thing as making my own faucet, and it is my understanding that any faucet will quickly stop working unless you rate limit your users, which is exactly the thing I don't want to do
