The Watara Supervision, also known as the QuickShot Supervision in the UK, is a monochrome handheld game console, originating from Asia, and introduced in 1992 as a cut-price competitor for Nintendo's Game Boy. It came packaged with a game called Crystball, which is similar to Breakout. One unique feature of the Supervision was that it could be linked up to a television via an official accessory. Games played in this way would display in four colors, much like Nintendo's Super Game Boy add-on for the SNES. A full color TV link was also in the works, but because of the Supervision's failure to make a major impression among gamers it was cancelled, along with the games which were in development for it.

Though the machine garnered some attention at launch (mainly due to the low price for the machine and its games, which many felt might enable it to make inroads into Nintendo's market share) it was ultimately unsuccessful in unseating the Game Boy from its position as the world's most popular handheld. Reasons commonly cited are the poor quality screen which was prone to blurring and made following the action difficult, a general lack of games and the simplistic nature of those that were released.

Yet another problem was that most of the games that were available were developed in Taiwan or Hong Kong, meaning that fans of big-name Western and Japanese developers were underwhelmed by the apparent lack of support from these companies. Only a tiny handful of games were developed by third parties, including Sachen and the British developer B.I.T.S. Up against Nintendo's list of popular franchises (Zelda, Mario, Metroid) and those of its third parties (Castlevania, Mega Man) - all of which eventually surfaced on the Game Boy - the Supervision's games were of little interest to most.

The Watara Supervision's main marketing point was its low price; the Supervision was US$49.95 in 1992 while the Game Boy was US$89.99. Games for the Supervision were also much cheaper than Game Boy games, and advertisements emphasized this price difference, with one British ad for the Supervision calling it "the affordable hand-held games machine". It was also bundled with headphones, batteries, and a Breakout clone titled Crystball.

To keep their costs down, Watara farmed out the international marketing and distribution to third parties leading to various versions:

In the mid 1990s, the Supervision was once offered as a final prize on the television game show Legends of the Hidden Temple (as well as Masters of the Maze). It was also offered as a prize on the premiere of the similarly short-lived The New Price is Right in 1994.

Quickshot's UK version of the Supervision was heavily featured for a time on ITV's gaming show Bad Influence! Presenter Violet Berlin could be seen playing a Supervision in many of the show's publicity photos.

A prototype of the Supervision was exhibited at the Winter Consumer Electronics Show in 1992. The Supervision was released before Christmas 1992 with eighteen launch titles, and it was advertised that fifty games were released by November 1992. The Supervision's game library was criticized for being 'too simplistic' compared to that of other consoles, which outweighed the value of their budget price, which ranged from US$8.95 to US$14.95 per game. One critic from Electronic Games said in respect to the Supervision that "it is still possible to be disappointed in a game that costs under fifteen dollars". Soon after the Supervision's release, the Game Boy Basic packaging option was announced, which made the Game Boy more affordable, costing only ten dollars more than the Supervision; this undermined the Supervision's 'budget' marketing strategy.
