Lucky-7

Lucky-7 is a puzzle arcade game developed by Forcefield and released in June 1987 in Japan and November 1987 in North America. It is the company's first arcade game since New Galaxy Shot in 1980 and is the first to run on Forcefield Ultra hardware.

Gameplay
The player uses the joystick to control a white cursor on the screen. Each level presents a type of block that the player must destory, and once the blocks bounce into view, the player must quickly select it and press the fire button to destroy it. The player can come across a "7" block, which will change all blocks on the screen to that of the target block. Multiple blocks of the same kind can appear on-screen, and if the player destroys all of them successfully, they will earn a hefty amount of bonus points. If the player destroys a block that does not match the target block, then the player will lose a life; and if all lives are lost, the game will be over.

Sequel and spin-offs
A spin-off title was released in 1995 for the Super Famicom in Japan, ''Ikoi! Lucky-7 Densetsu Douchuuki'' (lit. "Let's Go! Lucky-7 Adventure Travel Journal"). It is a platformer game that stars the character of Lucky as he travels across the world and defeating various enemies. It was only released in Japan due to the game's questionable content, such as the player being able to explore hell and that the boss of that specific area is an inverted cross. The game was released on the Wii Virtual Console in Japan on July 20, 2009, and was finally given an international release in 2017 as part of the Forcefield Archives compilation for Nintendo Switch, PlayStation 4, Xbox One and PC.

A redemption game titled Capsule-7 was released in 1997 for arcades in Japan; despite the name and the main character being near-identical to characters from Lucky-7, it bears very little relationship with the latter. A redesign was made in 2014 titled Capsule-7 EX.

The game received a sequel, Lucky-7 Neo, in 2015 for arcades, almost 30 years after the original title; Lucky-7 Neo features upgraded gameplay and graphics, and uses a light-gun instead of the traditional joystick and buttons.

Legacy
The game's mascot, named "Lucky", would go on to appear in several other Forcefield video games, most notably the Fantastic Journey series and Forcefield WakuWaku. The game Puzzle Club DS features a hidden bonus stage based on Lucky-7 that can be unlocked by completing ten rounds in Normal Mode.
