"Rus has adapted a very clever Max Maven idea and applied it to cards. The result is a very interesting and very easy version of the ACAAN effect."
- Marc Paul
"You have created a wonderful piece of mystery here and I'm getting strong reactions when performing it."
- Paul Rohmany
"Abacus is a combination of devious creativity and boldness. Rus has had numerous great additions and nuances to this plot over the years but he's really nailed it here. If you like the plot and want something your going to use I highly recommend Abacus."
