Solomon's Key

Some levels contain pipes through which Dana can go, burning jars that melt ice or moving monsters instead of flames. There are ten worlds plus five secret worlds that contain ten levels. The first nine worlds can be played in any order. The tenth level of a world usually features a special challenge like moving flames or monsters and lava that is slowly rising from the bottom.

The aim of the game involves players extinguishing all fires in a level in order to proceed. They do this by creating and melting ice (in a Lode Runner style) or kicking ice onto the fires. This game also has a level editor (which may expose some bugs that substantially affect the game mechanics).

Solomon's Club is a puzzle game, developed by Graphic Research and published by Tecmo, which was released in 1991.

The players, up to four at once in the arcade version, select among four playable fantasy-based characters; Thor the Warrior, Merlin the Wizard, Thyra the Valkyrie, or Questor the Elf. Each character has his or her own unique strength and weaknesses. For example, the Warrior is strongest in hand-to-hand combat, the Wizard has the most powerful magic, the Valkyrie has the best armour and the Elf is the fastest in movement. Upon selecting a playable character, the gameplay is set within a series of top-down, third-person perspective mazes where the object is to find and touch the designated exit in every level. An assortment of special items can be located in each level that increase player's character's health, unlock doors, gain more points and magical potions that can destroy all of the enemies on screen. The enemies are an assortment of fantasy-based monsters, including ghosts, grunts, demons, lobbers, sorcerers and thieves. Each enters the level through specific generators, which can be destroyed. While there are no bosses in the game, the most dangerous enemy is "Death", who can not only drain a character's health, but is difficult to destroy. As the game progresses, higher levels of skill are needed to reach the exit, with success often depending on the willingness of the players to cooperate by sharing food and luring monsters into places where they can be engaged and slaughtered more conveniently. While contact with enemies reduces the player's health, it also slowly drains on its own, thus creating a time limit. When a character's health reaches zero, that character dies. The character can be revived in place with full health by spending a game credit (i.e. inserting a coin) within a certain short time window after it died. This allows even the least proficient players to keep playing indefinitely, if they are willing to keep inserting coins.

Ghosts 'n Goblins is a platform game where the player controls a knight, named Sir Arthur, who must defeat zombies, ogres, demons, cyclops, dragons and other monsters in order to rescue Princess Prin Prin, who has been kidnapped by Satan, king of Demon World. Along the way the player can pick up new weapons, bonuses and extra suits of armor that can help in this task. The game is often considered very difficult by arcade standards and is commonly regarded as one of the most difficult games ever released. The game is considered by Gametrailers.com to be the world's second most difficult game ever made. The player can only be hit twice before losing a life (the first hit takes away Arthur's armor, and the player must continue on in his underwear until completing the level, or finding replacement armor). If the player loses a life, he is returned to the start of the level, or the halfway point if he has managed to get that far. Furthermore, each life can only last a certain length of time (generally around three minutes), the clock being reset at the start of a level. If the clock does run out, the player instantly loses that life. After defeating the final boss, but only with the cross weapon (if the player does not have the cross weapon, they will be prompted that it is needed to defeat the boss and restart at the beginning of level 5 and must repeat round 5 and 6 again regardless if the weapon is obtained immediately or not) for the first time the player is informed that the battle was "a trap devised by Satan". The player must then replay the entire game on a higher difficulty level to reach the genuine final battle.

In the game, each player controls one of the two Bubble Dragons, Bub and Bob. The player can move along platforms, as well as jump to those above and to the side, similar to most platform games. The player can also blow bubbles. These can trap enemies, who are defeated if the bubble is then burst by the player's spiny back. Bubbles that contain enemies can be popped at the same time resulting in different foods being projected around the level. Each enemy trapped in a bubble equates to a different food. Food is consumed and transferred to points (an increasing scale of 1000 points is awarded for each enemy burst in tandem with another meaning: one enemy burst equals one food item worth 1000 points, two enemies burst equals two food items worth 1000 and 2000 points, three enemies burst equals three food items worth 1000, 2000 and 4000 points, and so on), which results in earning lives. These same bubbles also float for a time before bursting, and can be jumped on, allowing access to otherwise inaccessible areas. Players progress to the next level once all enemies on the current level are defeated. Enemies turn "angry" — becoming pink-colored and moving faster — if they are the last enemy remaining, escape from a bubble after being left too long or a certain amount of time has been spent on the current level. A monster will also become angry if either player collects a skull (the only negative item in the game), and the monster is hit by the resulting comet crossing the screen (however, this is a rare occurrence). After a further time limit expires, an additional invincible enemy appears for each player, actively chasing them using only vertical and horizontal movements. These do not need to be defeated to complete the level, and disappear once a player's life is lost. Contact with enemies and their projectiles (rocks, lasers, fireballs, etc.) results in death.

Diggger is an action game in which the player digs tunnels, attempting to collect all of the emeralds on each level without being caught by monsters. The regular 'Nobbin' monsters are easily outwitted at first since they can't dig tunnels for themselves. However the game becomes more difficult as the amount of dug tunnels increases, and superior 'Hobbin' monsters begin to appear.

The gameplay for Ghouls 'n Ghosts is similar to that of Ghosts 'n Goblins. The player controls the knight Arthur, who must advance through a series of eerie levels and defeat a number of undead and demonic creatures in his quest to restore the souls stolen by Lucifer (Loki in the English-language Mega Drive and Sega Master System versions), including the soul of his lover, Princess Prin Prin. Along the way, Arthur can pick up a variety of weapons and armor to help him in his quest. While the core gameplay remains the same as its predecessor, the game now allows Arthur to fire directly upward and directly downward while in mid air. By jumping in certain spots, players can cause a treasure chest to erupt from the ground. By firing his weapon at the chest, players may uncover new weapons, gold armor or an evil magician that changes Arthur into an elderly man or a helpless duck. The gold armor allows players to charge up the weapon to release a powerful magical attack. Each weapon has its own special attack. There are five levels and Lucifer's chamber at the end, considered a sixth level in itself. To defeat the game, Arthur must complete level 1 to 5 twice. Upon completing level's 1 to 5 the first time, Arthur is taken back to level 1 again but this time a special weapon appears during the game. To enter Lucifer's chamber the player must have this special weapon equipped and defeat the penultimate boss.
