Gunpey

, often written as Gun Pey or GunPey, is a series of puzzle video games released by Bandai. It was originally released for the WonderSwan, and has been ported to WonderSwan Color, PlayStation, Nintendo DS and PlayStation Portable. The game was named as a tribute to the developer of the game, Gunpei Yokoi. He is known for developing several handheld consoles such as Nintendo's Game Boy, Virtual Boy, and Bandai's Wonderswan system. In the series, players move line fragments vertically in a grid in order to make a single branching line connect horizontally from one end to the other. The objective of the game depends on the selected game mode.

==Gameplay== thumb|left|144px|Screenshot of "Stage Mode" Gunpey features a 5×10 cell grid and line fragments spread across it varying from shapes such as caret (∧), inverted caret (∨), left slash (\), and right slash (/). The player controls a cursor that can be moved around the playing field. The cursor only ability is to flip vertical adjacent cells, allowing the player to move line fragments or switch them with another segment. The goal of the game is to piece the broken lines together to form a connected line that connects horizontally from one end to the other. After a line is completed, the line will temporarily flash and disappear. The player can connect additional branching segments while it's flashing to achieve a combo bonus. A bonus is also awarded when all of the line segments are cleared from the playing field. "Endless Mode" features line fragments appearing from the bottom of the grid and gradually move to up to the top as more pieces appear. The rate at which the new pieces scroll up from the bottom increases as the levels go on. The game ends if any line fragments reach the top of the screen before they have been assembled into a full line. "Stage Mode" bears a resemblance to Endless Mode. The goal is to clear lines using a specific number of line fragments as they appear from the bottom of the grid. Once the number of lines has been cleared, the player can move on to the next stage. The number of used line fragments needed to clear a stage and the rate of new line fragments appearing increases as more stages are cleared. "Puzzle Mode" features a specific number of lines are set per each stage. All the line fragments must be connected without a single line remaining. "Story Mode" is a mode where the player battles against the CPU in order to progress the story. The goal is to clear lines with a certain number of lines similar to Puzzle Mode, however the CPU adds several mechanics that may affect progress such as shadowed-panels, side-scrolling grid, and falling bombs that can be thrown upwards against the CPU. A vertical gauge is also featured. If the gauge is filled completely, the shadowed-panels disappear. The Story revolves around a frog named Vincent as he saves a cat named Sherry from a group of outlaws. In Tarepanda no Gunpey, the story revolves around Tarepanda as he rolls around reaching specific destinations around the Earth and collecting photos of different Tarepanda slowly becoming a pile of Tarepandas. "VS mode" allows two players to battle against each other. Players can choose difficulties between High, Normal, Low, and Poor. "High" rewards less SP per clearing a line as "Poor" rewards more SP.
