Game & Watch Gallery 4, known as Game & Watch Gallery Advance in Europe and Australia, is the fourth in a series of compilations of the classic Game & Watch games made between 1980 and 1991. Like the previous incarnations in the series, the featured games have both Classic modes, which attempt to recreate the look of the original unit as faithfully as possible, and Modern modes, which feature all-new graphics, music, and, often, gameplay elements. It is the first, and only game in the series to be on the Game Boy Advance.
Like all other games in the series, Game & Watch Gallery 4 features a system to unlock bonus features. As before, every 200 points in the high score for a game earns the player one star, up to five per game. That is, a high score between 200 and 399 is worth one star, 400 - 599 is two stars, 600 - 799 is three stars, 800 - 999 is four stars, and 1000 and above is worth five stars. Each game counts its stars separately, (For example, the player cannot earn 150 points in one game and 250 points in another and earn two stars for the cumulative total.) and the total (Up to 220) is what unlocks new features in the game.
The "Gallery" is where most special features are unlocked. These include a sound test, a Game & Watch timeline, the credits, and nine games (listed below). However, the games must, in essence, be unlocked twice -- the first time a game is unlocked, the player is treated to a short write-up on the game and a video of the game in action. Later on, the player can unlock playable versions. After all the stars have been collected Link becomes playable in the final unlockable game Zelda.
Gameplay of Fire
in the modern version.
Game & Watch Gallery 4 features a total of 20 games, though only 11 have Modern modes:
 Primary Games
These games are playable from the beginning.
- Fire - Mario and Luigi must bounce their friends to safety after they jump out of the windows of Princess Peach's burning castle. In Classic, two firemen are helping pedestrians escape from a burning apartment, but if any of the pedestrians fall on the ground, the player receives a miss.
- Boxing* - Luigi must KO his opponents (Waluigi, Wiggler, and Boo) before they KO him. A star is earned for every three KOs.
- Rain Shower - Mario must move his friends away from the paint balloons dropped by Bowser in Modern Mode. Also, in Hard Mode, Waluigi will occasionally move the lines around to make things harder for Mario. In Classic, a man is trying to keep his clothes dry from the rain. On hard, crows move the lines around, much like Waluigi. If a shirt gets hit, the man rewashes it and the player gets a miss.
- Mario's Cement Factory - In the Modern version, Mario and Co. are working in a cookie factory, with the cement factory only present in the Classic Mode.
- Donkey Kong Jr. - Donkey Kong Jr. must collect keys to free his dad, which he does later in the game Donkey Kong II.
- Donkey Kong 3* - Mario must shoot bubbles to move fireballs and Boos towards Donkey Kong. In Classic mode, Stanley the Bugman must send the bees towards Donkey Kong.
In the games marked with a *, the Hard mode (Game B) is replaced with a two-player mode. Each time a game is played with two players, a star is earned regardless of the winner.
 Secondary Games
These games are unlocked by obtaining Stars. They are listed in the order in which they will be unlocked.
- Modern: Peach must cook food thrown into the air by the Mario Bros. and feed it to Yoshi.
- Classic: The player controls a chef, who is trying to keep food from falling to the floor. However, a cat sometimes interferes, and if a piece of food touches the floor, a mouse will grab it and the player gets a miss.
- Mario Bros.
- Modern: Mario and Luigi try hard to make cakes in a factory while Bowser tries to stop them.
- Classic: Mario and Luigi make cakes that go up every time they touch one. If a cake falls to the floor, either Mario or Luigi get disciplined by their boss, which causes the player to get a miss.
- Donkey Kong
- Modern: Mario must avoid falling barrels and Koopas to save Princess Peach from Donkey Kong.
- Classic: Donkey Kong tosses barrels at Mario while he ascends a construction site. At the top, Mario must flick a switch and grab a swinging key. If the player hits a barrel, misses a key, or hits a moving construction beam, they get a miss.
- Modern: Mario must avoid octopus tentacles while he dives for treasure to give to Peach.
- Classic: Three people are taking turns trying to get the treasure from the octopus. If the player is caught, one of the three people will disappear, which counts as a miss.
- Fire Attack
- Modern: Wario must defend a giant golden statue of himself from Bob-ombs and Bullet Bills.
- Classic: A soldier must prevent the Indians from attacking his base, and if the Indians light his base on fire, the player gets a miss.
 Tertiary games
These games are unlocked in the Museum, can only be played in Classic Mode, and cannot earn the player stars.
- Manhole - The protagonist must hold up manhole covers in order to prevent the pedestrians from falling through holes in the floor.
- Tropical Fish - A man holds up fish bowls so that tropical fish can get from one fish tank to another by jumping from the fish bowl. If a fish falls to the ground, it will be eaten by a cat.
- Mario's Bombs Away - Mario must carry a bomb from one person to another across a jungle. Soldiers hide in the trees and try to light the bomb, and one of Mario's friends carelessly throws finished cigarettes to the ground, causing the nearby oil to ignite. Mario must also avoid all of this fire or his bomb will light.
- Parachute - A man must use his rowboat to catch people falling through the sky with their parachutes.
- Bombsweeper - John Solver goes inside a labyrinth-like sewer and tries to stop a bomb, set by Dynamite Jack, from exploding. If John doesn't stop the bomb in time, the maze will explode and the player will receive a miss.
- Climber - Climber must make his way up 25 floors. If he stands on top of a non-platform floor, he will go back down a few floors and get a miss. There's no Game B for this title.
- Safe Buster - A bank guard is preventing bombs thrown by The Wily Bomber from hitting his safe by disposing of them on either side of the screen. If the bomb catcher is full and the bomb touches the safe, the safe is blown open. The Wily Bomber then takes the money, and the player gets a miss.
- Lifeboat - Two men are trying to save the people from a burnt ship. The little raft can carry only four people, and if the player tries to catch a fifth person, the person falls into the water and the player gets a miss.
- Zelda - A port of the Zelda Game & Watch in which Link must battle monsters, including dragon bosses, in order to collect pieces of the Triforce. When he completes the Triforce, Zelda is freed from her prison.

- Game & Watch Gallery 4 also includes 1-Up Hearts. These appear after 200, 500, and 700 points in most games, and would replenish a life that was lost.
- A "Very Hard" mode called Star Mode is also included. It is unlocked for every game, with the exception of Donkey Kong 3 and Boxing, after getting above 1000 points in Modern Mode.
- 3-Up Moons appear in the modern versions of the games, Fire and Rainshower. In Fire, they would fall from the burning building at times, like Yoshi, Toad, and Donkey Kong Jr. would, but failing to bounce it to the cart would not count as a miss. In Rainshower, they can be collected until the 3-up Moon meter fills up, which causes Bowser to fall, and gives the player points.
