Cadillac II (known in North America as Square Deal: The Game of Two Dimensional Poker ) is a video game developed by Hect for the Game Boy. This version serves as the sequel to the Family Computer game Cadillac.

The game uses cards to create hands based on poker. A full deck of 52 playing cards are shuffled and the top four cards are shown to the player. Each card drops down one at a time to a grid of 25 potential playing spaces. A winning poker hand must be made in order to eliminate the cards (i.e., royal flush, straight flush, full house). Players can only place cards horizontally or vertically; never diagonally. Players advance to the next level when all 52 cards have been removed. Each level gives players less time to think about their moves and the ability to have decision-making pauses.

Players start with $1000 in gambling money. However, an increasing number is required for the ante at the beginning of each new level. Antes start at $500 (in the early stages) and work their way up to $3000 (in the later stages). If he cannot make the ante, then it results in an automatic game over. Failing to eliminate all 52 cards results will result in a penalty being deducted from the player's earnings for each card left over. If the player is forced to use the "hidden" sixth row anytime during single-player play, it results in a game over. The sixth row is permitted during the two-player challenge. However, it makes the bottom row disappear.

After winning level 10 on single-player mode; the player will have beaten the entire game.

Castelian is based off the original arcade game Nebulus. It was develped by Bite Studios and released in North America by Triffix and by Hiro Entertainment in Japan, in 1991.

Castelian is a platform game with some distinctive unique features. The player character, a small green creature called Pogo, is on a mission to destroy eight towers that have been built in the sea, by planting bombs at the towers' peaks. Pogo's progress is hindered by enemies and obstacles, which he has to avoid in order to reach the top of the tower.

The actual game play happens at each tower in turn. Pogo starts from the bottom and has to find his way up to the top. The towers are cylinder-shaped and have ledges on their outside, either horizontal, forming stairs or connected by elevators. Because of the cylindrical shape, the towers have no "left" or "right" edges, instead allowing Pogo to walk all around the tower.

A graphical innovation, and perhaps the most notable feature of the game, is that when Pogo walks left or right, he always stays in the centre of the visible screen. Instead of the Pogo sprite moving, the tower behind him turns clockwise or counterclockwise with a convincing sense of depth. This was featured favourably in reviews of the game.

Along his way to the top of the tower, Pogo encounters many different enemies, mostly shaped like basic geometric shapes. Pogo can shoot some of the enemies, while some are impervious to shooting. Contact with an enemy knocks Pogo down to the ledge below. If there is no ledge below, Pogo falls into the sea and drowns.

Your task: to restore peace to the realm of Jokerina.

In the first Castlevania Adventure, the fearless vampire hunter Christopher Belmont fought toe-to-toe and whip-to-wing against the vampire king, Count Dracula. Belmont defeated the Count and destroyed his castle, but unfortunatley Dracula used what remained of his magical powers to transform his body into mist, thereby making good his escape. However, his powers were so depleted that he was left unable to tranform into "human" form. The count decided to wait and rebuild his dark forces. Deep inside his black heart he swore revenge on Christopher Belmont and his family.

Fifteen years later, a ceremony was held in the town of Transylvania. The son of Christopher Belmont, Soleiyu Belmont, had come of age, and it was time for the title of vampire hunter to be passed down to him. The ceremony was used to commemorate this occasion. All the citizens of Transylvania rejoiced, hoping that the father-son team of vampire hunters would bring peace to the region forever.

But on the morning after the ceremony, it was discovered that Soleiyu Belmont had vanished into thin air. The ceremony was the chance Dracula had waited for. Soleiyu received great sacred power in the ceremony to mark his adulthood, and Dracula used his last bit of magic to turn Soleiyu's powers against him, tranforming him into a terrible demon. Then, aided by the Soleiyu-demon, Dracula was able to assume human form once again. That evening, to the northeast of the village, the earth shook with a thunderous roar and four ominous castles appeared. And, hidden in a lake at the center of these castles, was another castle---the new lair of Count Dracula!

Horrified to learn that his son had been altered by the forces of evil, Christopher Belmont determined to save Soleiyu and break the ambitions of the Count. He journeyed to the new castles, each ruled by a different power of darkness placed there by the Soleiyu-demon to stop anyone who would tamper with the mystic spell Dracula had cast upon him. Nevertheless, in order to save the village of Transylvania and free his son, Christopher had no choice but to go and fight once again.

Castlevania: The Adventure, known as Dracula Densetsu in Japan, is a platform game released for the Game Boy in 1989. It is the first Castlevania title for the system. Castlevania: The Adventure was re-released as part of the Konami GB Collection compilations in Japan and Europe.

Set a century before the events of the original Castlevania, the player controls an ancestor of Simon Belmont named Christopher Belmont who goes on a quest to defeat Dracula.

The game consists of four stages, and unlike other Castlevania games, there are no sub-weapons, but hearts are used to restore health. The player has three lives, after which the game ends. Weapons can be upgraded, such as the whip into the chain whip and flame whip, but any enemy damage will downgrade an upgraded weapon. There are no stairs, unlike other Castlevania games. At the end of each level, there is a "primary evil" to confront. Players can utilize crystals, hearts, and crosses of gold. There is also a point counter, and at 10,000 points, a player receives an extra life, and also receives one for every 20,000 points after that. Each stage also has a time limit in which to complete the level.

It was the Middle Ages in Transylvania. One man came into possession of an evil power, and the Prince of Darkness was born. Before long, this being used his new-found supernatural powers and the magic powers of his followers to spread his plague of darkness and despair throught the European continent. He was Count Dracula. Even to mention the name of this Prince of Darkness was to cast fear into the hearts of he people in the land, who were powerless to do anything save voice their concern. However, at about the same time a baby girl possessing special powers was born to a family living in a remote area of the country. "Your powers are meant for a higher purpose and not only for yourself," she was often reminded as she was growing up. The plot of this girl's fate began to develop one night in her seventeenth year when she met up with the young enigmatic Alucard, who was on a journey to search for the father that deserted him. The young girl's name was Sonia Belmont, and she was the first of the vampire hunters in the Belmont family to become legendary.

Catrap (known as Pitman in Japan) is a puzzle-platform video game released by Asmik for the Nintendo Game Boy in 1990

Catrap is a puzzle game. The player manoeuvres the player, an anthropomorphic cat, to navigate a room while clearing obstacles and kicking monsters and ghosts off the screen. Once the player has knocked all of the enemies off the screen, he advances to the next level. Advancement can prove difficult for the player as increasingly intricate obstacles are presented to overcome all of the monsters and ghosts. Arguably, the easiest route to solve the problem is through trial and error. A player may try one combination of manoeuvres by moving the obstacle in one direction, then he may find himself trapped. The player can hit the 'A'-button to reverse his movements and try again in a different way until he finds the solution that enables him to access all of the baddies to knock them off the screen. Trial and error seems to make up a large portion of the game. Players can also create their own mazes.

Cave Noire is a Role-Playing game, published by Konami, which was released in Japan in 1991.

Centipede is a vertically oriented shoot 'em up arcade game produced by Atari, Inc. in 1981. It was ported to the Game Boy in 1995

The player is represented by a small, "somewhat humanoid head" at the bottom of the screen, later depicted as a caped, elf-like character on the Atari 2600, Atari 5200 and Atari 7800 cartridge graphics (though described as being a garden gnome in the trivia section of the cell phone interpretation). The player moves the character about the bottom area of the screen with a trackball and fires laser shots at a centipede advancing from the top of the screen down through a field of mushrooms. Shooting any section of the centipede creates a mushroom; shooting one of the middle segments splits the centipede into two pieces at that point. Each piece then continues independently on its way down the board, with the first section of the rear piece becoming a new head. If the head is destroyed, the section behind it becomes the next head.

The centipede starts at the top of the screen, traveling either left or right. When it hits a mushroom or the edge of the screen, it drops one level and switches direction. Thus, more mushrooms on the screen cause the centipede to descend more rapidly. The player can destroy mushrooms by shooting them, but each takes four hits to destroy.

If the centipede reaches the bottom of the screen, it moves back and forth within the player area and one-segment "head" centipedes are periodically added. This continues until the player has eliminated both the original centipede and all heads. When all the centipede's segments are destroyed, a new centipede forms at the top of the screen. Every time a centipede is eliminated, however, the next one is one segment shorter and is accompanied by one additional, fast-moving "head" centipede. A player loses a life when hit by a centipede or another enemy, such as a spider or a flea. The flea leaves mushrooms behind when fewer than five are in the player area, though the number required increases with level of difficulty. Spiders move across the player area in a zig-zag fashion and occasionally eat some of the mushrooms.

Scorpions poison every mushroom they touch, but these never appear in the player's movement region. A centipede touching a poisoned mushroom hurtles straight toward the player's area. Upon reaching the player's area, the centipede returns to normal behavior.

Chachamaru Boukenki 3: Abyss no Tou is a Role-Playing game, published by Human Entertainment, which was released in Japan in 1991

Chalvo 55 is a puzzle video game released in 1997 by Japan System Supply. It features the same main character as the cancelled Virtual Boy game Bound High.

Players control a robot named Chalvo; who can change forms into a ball. Five crystals are needed in order to reach the boss of each level. Enemies and spikes must be avoided or defeated at all times.

Often, the boss of the level operates a trap through a control panel and players must devise a workaround in order to defeat him. One of the glitches in the game is that the player can operate the trap (sometimes on himself) after the boss is defeated simply by activating the control panel. Eight stages are present in the game; with a secret password responsible for hiding a secret ninth level.

Players can view an area map in addition to a larger world map that states their position within the entire game. Movable hard blocks can be relocated in order to reveal hidden passageways; often with a crystal nearby.

You can shoot some stick in four different modes: Tournament, Party, Freestyle, and Challenge. Tournament pits you against the best players the computer can offer. If you keep missing shots, you can use the Challenge mode to get in some practice. The Freestyle mode lets you create your own games, and if you have a lot of friends the Party mode will let up to eight people play using the same Game Boy. Every kind of billiards game is available including 3-Ball, 9-Ball, 8-Ball, 10-Ball, 14-1 Continuous, Rotation, 15-Ball, Straight Pool, Equal Offense, and Speed Pool.
