In Japan, モグラ退治 (mogura taiji, "Mole Buster") is a popular arcade game invented in 1975 by Kazuo Yamada of TOGO, based on ten of the designer's pencil sketches from 1974, licensed to Bandai in 1977. It can also be commonly found at Japanese festivals.
A typical Whac-A-Mole machine consists of a large, waist-level cabinet with five holes in its top and a large, soft, black mallet. Each hole contains a single plastic mole and the machinery necessary to move it up and down. Once the game starts, the moles will begin to pop up from their holes at random. The object of the game is to force the individual moles back into their holes by hitting them directly on the head with the mallet, thereby adding to the player's score. The more quickly this is done the higher the final score will be.
The cabinet has a three-digit readout of the current player's score and, on later models, a best score of the day readout. The mallet is usually attached to the game by a rope in order to prevent anyone from walking away with it.
Current versions of the Whac-A-Mole include three displays for Bonus Score, High Score as well as current game score. Home versions, as distributed by Bob's Space Racers, include one display to show the current score.
If the player does not strike a mole within a certain time or with enough force, it will eventually sink back into its hole with no score. Although gameplay starts out slow enough for most people to hit all of the moles that rise, it gradually increases in speed, with each mole spending less time above the hole and with more moles outside of their holes at the same time. After a designated time limit, the game ends, regardless of the skill of the player. The final score is based upon the number of moles that the player struck.
In addition to the single-player game described above, there is a multi-player game, most often found at amusement parks. In this version, there is a large bank of individual Whac-A-Mole games linked together, and the goal is to be the first player to reach a designated score, rather than hit the most moles within a certain time. In most versions, striking a mole is worth ten points, and the winner is the first player to reach a score of 150 (i.e., 15 moles). The winner receives a prize, typically a small stuffed animal, which can be traded up for a larger stuffed animal should the player win again.
Game play options have become more adjustable, allowing the operator and/or owner to selectively alter the high score, hits points, rate of progressive speed as well as the game time.
The original Whac-A-Mole game inspired the first genre of games with a violent aspect as central to their user experience. Researchers have used Whac-A-Mole and its variations to study the violent aspects of these games.
The Whac-A-Mole game trademark is owned by Bob's Space Racers. Machines with similar gameplay are sold under other names. Whac-A-Mole has also been the basis for a number of internet games and mobile games that are similar in play and strategy.
The moles are mounted on rods and raised by a lever and crank system. When the user strikes the mole, a microswitch is activated by a pin housed within the mole and the system lowers the mole.
The timing of the moles was originally controlled by tones from an audio tape which then drive an air cylinder system; however, this may have been updated more recently.
The term "Whac-a-mole" (or "Whack-a-mole") is used colloquially to denote a repetitious and futile task: each time a task is finished or a problem is dealt with, yet another task/problem appears elsewhere. In a military context, the term is used to refer to ostensibly inferior opposing troops who keep re-appearing. In a programming/debugging context it refers to the fact that fixing a bug has a certain chance of creating a new bug which itself needs to be fixed. In a web context, it refers to the process of fending off recurring spammers, vandals or miscreants. It has also been used of fake news stories.
