Eggerland

The series consists of several puzzle games developed by HAL Laboratory. Its first release was in 1985 for MSX computer systems. Many titles were made in the series and the gameplay is almost exactly the same in every game as well. Only a few changes were made over the years (mainly graphical).
The hero of most games is Lolo, a blue, spherical character with eyes, arms, and legs. The story mainly deals with King Egger, the villain, capturing princess Lala, who is similar to Lolo, only colored pink or red, and wearing a bow. Lolo must rescue Lala by travelling through Egger's domain and solving the puzzle rooms laid out before him.
List of titles.
Many video games of the Eggerland series were only released in Japan and some only in the West. Below is a list of all video games and their respective releases.
Although the graphics and game engine of the Japanese "Adventures of Lolo" are identical to those of the Western "Adventures of Lolo 2", the stages are different and harder. They are actually separate video games. The Japanese "Adventures of Lolo 1 & 2" include original stages, whereas the American "Adventures of Lolo 1 & 2" are compilations of stages taken from earlier Japan-only titles. The American "Adventures of Lolo 3" includes mostly original stages, instead.
Gameplay overview.
Basics.
The player must guide Lolo through a room of 11×11 tiles and have Lolo collect all of the Heart Framers (sometimes referred to as HFs) in the room. Doing so opens up a Jewel Box, which contains an item (sometimes a key or jewel). Successfully acquiring the contents of the Jewel Box will clear the room of all monsters and open the way to the next room(s). Players need to navigate Lolo past the many monsters seen throughout the rooms — some are harmless while others are deadly.
Lolo's only weapon is a Magic Shot. Two shots (and always two shots) are obtained by collecting certain Heart Framers (sometimes referred to as SF's for Shot Framers). Heart Framers containing magic shots are not differentiated in appearance from regular Heart Framers. Collecting a Heart Framer that does contain magic shots, however, is normally indicated by a different sound effect than a regular Heart Framer's. Magic shots allow Lolo to temporarily turn enemies into Eggs, which can be pushed around, but not pulled. Monsters in eggs will hatch after a few seconds. If Lolo shoots an egg a second time, it will fly off the screen, though the monster will reappear at its original starting point a few seconds later. Reappearance is typically indicated by an outlined box of sorts and then the monster physically appearing very shortly afterward. Lolo may move through the outlined box unhindered.
If a monster's starting point is covered with an Emerald Framer or another monster and there are no warp holes in the level, the monster will not return to the level. Lolo himself cannot cover a monster's starting point to cause this to happen. If Lolo is on a monster's starting point and it reappears, Lolo will be "on top" of the monster and can usually walk off of it, though some monsters like Almas or Skulls will kill Lolo if he is standing on their starting points.
Terrain and obstacles.
There are various types of terrain and obstacles in the levels. Emerald Framers, or EFs, are green blocks that Lolo may push around freely, but he cannot pull them. Lolo cannot push multiple, stacked EFs at one time. This is similar to the game Sokoban. EFs are typically used to block dangerous monsters or ranged attacks from other monsters. One type of terrain is the grass (sometimes called flower bed), which Lolo may walk freely on, yet any mobile monster cannot enter the grass on its own. If Lolo pushes a monster in an egg onto the grass, the monster will try to walk off after the egg hatches. Another type of terrain is the sand. Lolo will only move at half speed while on the sand, but any mobile monster is unaffected by the sand's slowing effects. If Lolo is only halfway on the sand, he will not be affected.
Some other obstacles include trees and rocks. Both of these block movement from Lolo and monsters. Monsters that have a ranged attack, like Medusas or Gols, can shoot through the trees, but Lolo cannot. Rocks prevent shots from both Lolo and monsters. Another obstacle is the one-way arrows. Lolo can enter these arrows from any direction except the direction the arrow is pointing. For instance, if the arrow is pointing up, Lolo cannot walk down against the arrow. One-way arrows do not stop monsters in any way, nor do they prevent any shots from Lolo or monsters.
Some levels contain water or lava. Neither prevent shots from Lolo nor monsters from going through and both prohibit movement from Lolo and monsters. There are sometimes bridges going over the water and lava and both Lolo and mobile monsters can cross the bridges freely. With water, Lolo can push a monster in an egg onto the water to act as a temporary bridge. Typically, levels are laid out so Lolo can go to the other side of the waterway. An egg sinks quickly after being pushed into the water. If Lolo is on an egg and it sinks, Lolo will be killed. Some waterways even have currents which Lolo can ride eggs on to other parts of the level. Eggs will sink upon reaching the end of the current. An egg that sinks in the water will remove the monster from the level temporarily, but the monster will reappear in its original starting point (just like hitting it as an egg with a second magic shot). There can only be one egg on any water part of the level at any time. A second egg may "not" be put into the water until the first one sinks. Eggs may not be pushed into the lava.
Another tricky obstacle that was only featured in "Adventures of Lolo 3" is the crumbling bridge. These bridges can only be crossed twice. The first time will make the bridge crack. The second time, the bridge will crumble away, leaving either water or lava behind. Lolo must be fully on the bridge to qualify it for being crossed. If Lolo only walks halfway on these bridges and walks off, they will not be damaged. Any monster walking over these bridges will not cause any damage to them.
Warp holes.
One final trick that appears in most games are the warp holes. Some levels, but not all, have pre-defined locations for a monster to alternately appear if it is removed from the screen "and" its original starting point is covered. Its starting point may be covered with an EF or another monster. Also, an object need only cover a part of the original point. For instance, if an EF were only on 1/4 of the monster's original starting point, this would be sufficient enough to cover it. Lolo himself cannot cover a monster's starting point and cause it to be sent to a hole. For a demonstration of how a warp hole works, see the adjacent image showing a 3-step process.
The holes go in a numbered order and the monsters go to the lowest numbered hole available. If there were two holes, for instance, and both the monster's starting point and the first hole were covered, the monster would go to the second hole. Many games had a maximum limit of 8 holes per level, though rarely ever used this many.
One important thing to remember is that the monster's original spot needs to stay covered to send it to a hole. If Lolo removes a monster that was sent to a hole and its "original" starting point was uncovered, it would not continue going to the hole, but rather back to its original starting point. Though in some rooms, monsters may need to be sent back to their original starting point in order to solve the room.
If a monster is in the process of reappearing and Lolo covers its spot while this is happening (i.e. when the outlined box indicating a monster is about to reappear is there and gets covered), the reappearing process will fail and the monster will be permanently removed from the level. It will "not" be sent to a hole.
Powers.
In some levels, Lolo can obtain certain powers to help him. These powers include the Hammer, the Bridge, and the Arrow Turn (sometimes called a One-Way Pass). To obtain a power, Lolo must collect a certain amount of hearts, which is pre-defined in the data for any level that gives a power. This value varies from level to level. The maximum amount of powers a level can have is three. If the next heart to be collected will give Lolo a power, all hearts in the room will flash as an indicator:
To use any of these powers, Lolo simply needs to face the respective obstacle the power is used for and use the magic shot button. For arrows, Lolo may be facing the arrow from any direction, though care must be taken to ensure that Lolo is standing in the proper position, or a shot will be fired by accident instead.
Games.
"Eggerland Mystery".
 is a 1985 puzzle game for MSX computer systems produced by HAL Laboratory. It is the first game in the "Eggerland" series. Its main characters are named Lolo and Lala
"Eggerland 2".
Eggerland 2, known in Japan as , is a 1986 puzzle game for the MSX (and shows extra colors on MSX2) produced by HAL Laboratory. It is the sequel to the original "Eggerland Mystery" and the second game in the "Eggerland" series. The game is often referred to as "Shodai" (初代), or the "first "Eggerland"". The game features a total of 122 stages; the game is therefore presented in a 10-by-10 grid, plus 22 extra stages.
 is a port of "Meikyū Shinwa" for the MSX computer platform with updated graphics and different music. The game was released in Japan in 1987 for the Family Computer Disk System by HAL Laboratory.
"Eggerland: Meikyū no Fukkatsu".
 is a puzzle video game developed by HAL Laboratory for the Family Computer. It was released in 1988 in Japan as the fourth game in the "Eggerland" series following "Eggerland Mystery", and is the third in the series not counting the port of "Eggerland 2" made for the Famicom Disk System. The game contains roughly 162 stages (or maps), which are arranged on an 8-by-16 grid (with some stages hidden). This entry in the series would serve as the basis for "Eggerland – Departure to Creation", which reuses "Revival of the Labyrinth"'s core gameplay and presentation.
This game is more linear than its predecessor: Lolo (the player) can choose to go in two different directions only in a dozen of rooms. Similar to the key that is used to access new rooms of the dungeon, the raft makes its second appearance in the series as a room-completion prize which allows Lolo entry to the water courses in the southwest region of the game. "Revival of the Labyrinth" also has special inventory items that Lolo can collect along the way, such as a map and a "Magic Bell". Differences from "Eggerland 2"/FDS include the absence of time-based levels with special keys and Guardians/Gods as their prizes. Instead, these are given out for defeating rooms that lead to only one other room in the dungeon. Rather than the small key used to enter new rooms, the player may occasionally receive one of the game's special keys, which are used to open special doorways normal keys cannot open, and four of these special keys are used to access rooms closed off from the main dungeon map to obtain pieces of a large King Egger tablet required for access to the final levels of the game. Two other items that can also be obtained from chests are the map, which retains its usage from "Eggerland 2", and a new item: the Magic Bell, which rings in four specific rooms of the castle that contain entrances to special dungeons that if completed, award the player with one of the four Gods needed to finish the final rooms of the game, in a similar fashion to the Guardians from "Eggerland 2". These entrances to the God dungeons are not revealed like they were in the previous game; where the player had to move one specific Emerald Frame after the room's completion; Here the player has to align the Emerald Framers in a particular pattern to reveal the entrance. Alongside the Gods, Lolo can also encounter Buddhas that give out information in certain empty rooms.
"Eggerland: Sōzōhe no Tabidachi".
 is a Japanese puzzle video game in the "Eggerland" series by HAL Laboratory. It was published for the Family Computer Disk System in 1988. The game comprises 50 stages ("maps"), and progresses linearly (unlike previous titles, such as "Meikyū Shinwa" and "Eggerland – Revival of the Labyrinth"). "Construction Mode" enables the player to create a custom map. The game is shorter than earlier "Eggerland" titles, and many of the maps are reproduced from "Eggerland Mystery".
