Great solution but variable naming and formatting could be improved to, combined with a docstring, turn it into really good production code.

Ruby 3.0 should be enabled, read this to learn how to do it

Please organize the structure of test fixture as following (although it has been mentioned in the attached link, I'm repeated here again)

describe "<This message should describe the categories of test groups inside this block>" do
  it "<A short message describing this test group>" do
    expect(...).to eq(...) #Assertions
    #Or Test.assert_equals(user_response, reference_response)
  end
end

OK, seems to be fixed now :-) (moved something to the wrong place)

DIGITS dictionary moved to the preloaded section.

thanks for the translation!

True, but to be honest I did not have any other idea how to do it (except brute force) =/
