Roulette emerged in late 18th-century European casinos and has remained popular with gamblers to this day. In the game, a horizontal wheel is spun and a ball is dropped onto it. Players may bet on which of the wheel's numbered slots the ball will come to rest in, what color the slot will be, and whether the number will be odd or even. Though roulette is ostensibly a game of chance, players have repeatedly tried to improve their odds. How did one engineer exploit the game to win $325,000 in 1873?

Just 10 days before Mexico City hosted the 1968 Summer Olympics, government forces opened fire on student and civilian protesters gathered in a plaza in the Tlatelolco section of the city. The official government explanation was that students provoked the army's violence by firing at them from the buildings surrounding the plaza and that only four people had been killed. Investigations were thwarted until Vicente Fox became president in 2000. What is now believed to have happened that day?
Born on a day like today
Richard III was made a duke after his brother Edward of York deposed the weak Lancastrian king Henry VI and assumed power. Richard and Edward were driven into exile in 1470 but returned and defeated the Lancastrians the next year. On Edward's death, Richard became protector for Edward's son, the 12-year-old King Edward V, but he usurped the throne and confined Edward and his brother to the Tower of London, where they were likely murdered. Who defeated Richard to become England's next monarch?
