Good question!
Considering, in North America that 43 U.S. states (Alabama, Alaska, Hawaii, Mississippi, Utah, Wyoming and Nevada do not have lottos*), all Canadian provinces, the District of Columbia, Mexico, Puerto Rico, and the U.S. Virgin Islands all run government-operated lotteries, and that elsewhere in the world official lottos exist in at least 100 countries (on every inhabited continent), the short answer is… a LOT!
