Interactive bets Oleg Zhuravsky proposed amendments to federal law No. 244-ФЗ "On state regulation of activities for organizing and conducting gambling,” which came into effect in 2014. Legislative innovations obliged bookmakers and organizers of parimutuel betting to join self-regulatory organizations (SRO), and introduced the notions of "interactive bets" and "the Сenter for taking interactive bets" (Russian: «Центр учёта приёма интерактивных ставок», ЦУПИС) through which bookmakers could be legalized via the Internet.
