The United States of America (USA), commonly known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.

Sudoku is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid contain all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution.

The World Sudoku Championship (WSC) is an annual international puzzle competition organised by a member of the World Puzzle Federation. The first event was held in Lucca in 2006. National teams are determined by local affiliates of the World Puzzle Federation. The competition typically consists of 100 or more puzzles solved by all competitors over multiple timed rounds, including classic sudoku, variations and other puzzle types, normally followed by a playoff for the top qualifiers to determine a champion. Examples of rounds include the Relay round, where an answer from one puzzle contributes digits to the start of the next sudoku, and the "World Record" round, in which solvers competed to set a Guinness World Record for fastest sudoku solution.

Early life and education

Thomas Snyder grew up in the suburbs of Buffalo, New York. [3] He attended Amherst Central High School before getting chemistry degrees from the California Institute of Technology and Harvard University [3] and doing post-doctoral work at Stanford University's bioengineering department. [1]

Buffalo is the second largest city in the U.S. state of New York and the largest city in Western New York. As of July 2016, the population was 256,902. The city is the county seat of Erie County and a major gateway for commerce and travel across the Canada–United States border, forming part of the bi-national Buffalo Niagara Region.

Amherst Central High School (ACHS) is a public high school in Snyder, New York, a hamlet within the town of Amherst, which is within the Buffalo-Niagara Falls metropolitan area. It is the only high school in the Amherst Central School District. Its enrollment is approximately 802 students. The school opened in 1931; construction on the current building began in 1929.

The California Institute of Technology (Caltech) is a private doctorate-granting research university in Pasadena, California. Known for its strength in natural science and engineering, Caltech is often ranked as one of the world's top-ten universities.

Thomas Snyder has contributed puzzles to various puzzle-related publications including GAMES Magazine and Wired. He has also written puzzles for events including the World Sudoku Championship, U.S. Puzzle Championship, the MIT Mystery Hunt, Gen Con, and the Microsoft Puzzle Picnic. [4]

Wired is a monthly American magazine, published in print and online editions, that focuses on how emerging technologies affect culture, the economy, and politics. Owned by Condé Nast, it is headquartered in San Francisco, California, and has been in publication since March/April 1993. Several spin-offs have been launched, including Wired UK, Wired Italia, Wired Japan, and Wired Germany. Condé Nast's parent company Advance publications is also the major shareholder of Reddit, an internet information conglomeration website.

The MIT Mystery Hunt is an annual puzzlehunt competition at the Massachusetts Institute of Technology. As one of the oldest and most complex puzzlehunts in the world, it attracts roughly 60 teams and 2,500 contestants annually in teams of 5 to 200 people. It has inspired similar competitions at Microsoft, Stanford University, Melbourne University, University of South Carolina, University of Illinois at Urbana–Champaign and University of Aveiro (Portugal) as well as in the Seattle, San Francisco, Miami, Washington, D.C., Indianapolis and Columbus, Ohio metropolitan areas. Because the puzzle solutions require knowledge of esoteric and eclectic topics, the hunt is often fused with popular stereotypes of MIT students.

Gen Con is the largest tabletop-game convention in North America by both attendance and number of events. It features traditional pen-and-paper, board, and card games, including role-playing games, miniatures wargames, live action role-playing games, collectible card games, and strategy games. Gen Con also features computer games. Attendees engage in a variety of tournament and interactive game sessions. In 2015, Gen Con had 61,423 unique attendees, making it one of the largest conventions in North America.

In early 2012, Snyder began his publishing company Grandmaster Puzzles. On April 9, 2012, he began selling his first title from the newly formed company, The Art of Sudoku. On December 31, 2012, Snyder began the newest version of his puzzle blog The Art of Puzzles coinciding with the relaunch of his Grandmaster Puzzles web site. [5]

Snyder holds several puzzle-solving titles as well, with his 2006 U.S. Puzzle Championship win being the earliest. Snyder has represented the United States ten times at the World Puzzle Championship, including six times when the US won the team competition (2006-8, 2010-11, 2013). He was the top individual at the 27th World Puzzle Championship held in Prague in November 2018. [6]

The World Puzzle Championship is an annual international puzzle competition run by the World Puzzle Federation. All the puzzles in the competition are pure-logic problems based on simple principles, designed to be playable regardless of language or culture.

Prague is the capital and largest city in the Czech Republic, the 14th largest city in the European Union and the historical capital of Bohemia. Situated in the north-west of the country on the Vltava river, the city is home to about 1.3 million people, while its metropolitan area is estimated to have a population of 2.6 million.
