Taxman games

Group Description

Games based around the "Taxman" concept, invented by Diane Resek in the early 1970s. From a limited pool of numbers, the player takes a number and gains the selected amount of points. However, the computer opponent then takes for himself all the numbers which are real factors of the chosen number. If no real factors are present, the number cannot be chosen by the player and is taken by the computer. The game ends when there are no more numbers available, at which point the player wins if he has scored more points than the computer.

In Germany, the game is known as "Zahlenhai" ("Number Shark").
