The Riddlers of Riddlemeree is a gargantuan, efficient nation, ruled by The Sphynx with an iron fist, and notable for its enslaved workforce, free-roaming dinosaurs, and daily referendums. The hard-nosed, cynical, humorless, devout population of 17.569 billion Riddlemereeans are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The medium-sized, corrupt, well-organized government juggles the competing demands of Law & Order, Defense, and Education. It meets to discuss matters of state in the capital city of Lidder. Citizens pay a flat income tax of 56.8%.

The frighteningly efficient Riddlemereean economy, worth a remarkable 3,443 trillion Gold Rhymes a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is an enormous, deeply entrenched black market in Arms Manufacturing, Uranium Mining, Information Technology, and Tourism. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an impressive 195,980 Gold Rhymes, but there is a large disparity between incomes, with the richest 10% of citizens earning 860,684 per year while the poor average 28,059, a ratio of 30.7 to 1.

New "Worker's Strike" laws set out who is allowed to strike a worker, teams of painters are converting road signs from horse lengths to kilometers, the breathalyser pledge is a traditional part of marriages in Riddlemeree, and the country is rumored to be a Brancalandian puppet state. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Riddlemeree's national animal is the Ghost, which is also the nation's favorite main course, and its national religion is Logic.

Riddlemeree is ranked 119,859^th in the world and 5^th in War Weary for Largest Publishing Industry, scoring 2,633.92 on the Bella Potter Productivity e-Index.
