Zoo Keeper started as an online puzzle video game developed by Robot Communications, but was soon ported by Success studio to the Nintendo DS and other platforms, including the Nintendo GameBoy Advance and the PlayStation 2.
The title was published by Success in its native Japan, on October 31, 2003 for the Nintendo GBA, on February 13, 2004 for the PlayStation 2 and December 2, 2004 for the Nintendo DS.
The game was also published by Ignition Entertainment in North America, on January 18, 2005 and in Europe, on March 11, that same year.
The whole objective of Zoo Keeper, as its name suggests, is to take care of a zoo and keep animals from overpopulating it.
You can do this by matching a line of three or more tiles in puzzle, either horizontally or vertically.
When the tiles are matched, they disappear, and cause others to fall down and fill the space.
The DS version used the upper screen of the portable console to display a special animal, which generated a bonus if you matched certain tiles and completed the puzzle.
This version of Zoo Keeper used the touchscreen to solve the puzzles, and allowed competitive matches between two DS owners.
While many have called Zoo Keeper a Bejeweled clone, the game differentiated itself from the popular PopCap title by allowing players to switch tiles on the board while another move was still being made, thus allowing gamers to set up bigger chain moves.
Zoo Keeper has three main modes, with the first being actually called Zoo Keeper, and takes players with a quota of animal tiles that needed to be removed in a certain amount of time.
The second game mode was called Tokoton, and tasked players with capturing a 100 of any animal tiles on the board without any time limit.
The last one is Time Limit, which made players capture certain animals in just six minutes.
