In computational complexity theory, a decision problem is PSPACE-complete if it can be solved using an amount of memory that is polynomial in the input length and if every other problem that can be solved in polynomial space can be transformed to it in polynomial time. The problems that are PSPACE-complete can be thought of as the hardest problems in PSPACE, the class of decision problems solvable in polynomial space, because a solution to any one such problem could easily be used to solve any other problem in PSPACE.
A cryptic crossword is a crossword puzzle in which each clue is a word puzzle. Cryptic crosswords are particularly popular in the United Kingdom, where they originated, as well as Ireland, the Netherlands, and in several Commonwealth nations, including Australia, Canada, India, Kenya, Malta, New Zealand, and South Africa. Compilers of cryptic crosswords are commonly called setters in the UK and constructors in the US. Particularly in the UK, a distinction may be made between cryptics and quick crosswords, and sometimes two sets of clues are given for a single puzzle grid.
A logic puzzle is a puzzle deriving from the mathematical field of deduction.

Mathematics can be used to study Sudoku puzzles to answer questions such as "How many filled Sudoku grids are there?", "What is the minimal number of clues in a valid puzzle?" and "In what ways can Sudoku grids be symmetric?" through the use of combinatorics and group theory.
The cigarette smokers problem is a concurrency problem in computer science, originally described in 1971 by Suhas Patil. The problem has been criticized for having "restrictions which cannot be justified by practical considerations."
Maze: Solve the World's Most Challenging Puzzle is a puzzle book written and illustrated by Christopher Manson. The book was originally published as part of a contest to win $10,000.
A standard Sudoku contains 81 cells, in a 9×9 grid, and has 9 boxes, each box being the intersection of the first, middle, or last 3 rows, and the first, middle, or last 3 columns. Each cell may contain a number from one to nine, and each number can only occur once in each row, column, and box. A Sudoku starts with some cells containing numbers (clues), and the goal is to solve the remaining cells. Proper Sudokus have one solution. Players and investigators use a wide range of computer algorithms to solve Sudokus, study their properties, and make new puzzles, including Sudokus with interesting symmetries and other properties.
A menthol cigarette is a cigarette infused with the compound menthol which imparts a “minty” flavor to the smoke. Menthol also decreases irritant sensations from nicotine by desensitizing receptors, making smoking feel less harsh compared to regular cigarettes. Some studies have suggested that they are more addictive. Menthol cigarettes are just as hard to quit and are just as harmful as regular cigarettes.
The Eternity II puzzle is an edge-matching puzzle launched on 28 July 2007. It was developed by Christopher Monckton and marketed and copyrighted by TOMY UK Ltd as a successor to the original Eternity puzzle. The puzzle was part of a competition in which a $2 million prize was offered for the first complete solution. The competition ended at noon on 31 December 2010, with no solution being found.
The eureka effect refers to the common human experience of suddenly understanding a previously incomprehensible problem or concept. Some research describes the Aha! effect as a memory advantage, but conflicting results exist as to where exactly it occurs in the brain, and it is difficult to predict under what circumstances one can predict an Aha! moment.
Tobacco smoking has serious negative effects on the body. A wide variety of diseases and medical phenomena affect the sexes differently, and the same holds true for the effects of tobacco. Since the proliferation of tobacco, many cultures have viewed smoking as a masculine vice, and as such the majority of research into the specific differences between men and women with regards to the effects of tobacco have only been studied in-depth in recent years.
Tobacco marketing targeting African-Americans is the practice of customizing tobacco products and advertising techniques specifically to African-American consumers. It is most commonly analyzed through the consumption of mentholated cigarettes, as it represents 47% of black adult smokers and 84% of adolescent black smokers.
Animals are exposed to tobacco smoke and other cigarette by-products through their use as experimental subjects and through contact with smokers, as in the case of pets in houses where smoking takes place.
Tobacco smoking is popular in North Korea and culturally acceptable among men, but not for women. As of 2019, some 43.6% of men are reported to smoke daily, whilst in contrast only 4.5% of women smoke daily, with most of these being older women from rural areas. Smoking is a leading cause of death in North Korea, and as of 2021 mortality figures indicate that 14.2% of North Koreans die due to smoking-related causes, which is the 6th highest rate after China, Greenland, Kiribati, Denmark and Micronesia. There are tobacco control programs in North Korea, and although smoking was not prohibited in all public spaces, the smoking rates have declined since their peak in the 2000s.
