Playing one\u2010line, a small credit gain (e.g. 2 cents) was a net win. In the 20\u2010line game it was a net loss of 18 credits but was still accompanied by \u2018winning\u2019 sights and sounds.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Most players (94%) preferred the 20\u2010line game.\n                      <jats:styled-content style=\"fixed-case\">PRPs<\/jats:styled-content>\n                      for small credit gains (net losses) in the 20\u2010line game were equivalent, or larger than in the one\u2010line game where such gains were wins.
