Solomon’s Key (ソロモンの鍵 Soromon no Kagi ) is a puzzle game developed by Tecmo in 1986 for arcade release on custom hardware based on the Z80 chipset. It is better known as a 1987 port to the Commodore 64 and the Nintendo Entertainment System, although it also appeared on many other game systems of the time, like the Sega Master System in 1988 and the Famicom Disk System, released in Japan on January 25, 1991.
Bomb Jack (ボンジャック Bon Jakku ) is an arcade platform game that was released in 1984 by Tehkan (known today as Tecmo). It was followed by two official sequels, the console and computer title Mighty Bomb Jack, and the arcade game Bomb Jack Twin.
The player controls Jack, a superhero who can leap and glide. Someone has planted 24 bombs at famous tourist sites (the Sphinx and Great Pyramids, the Acropolis, Neuschwanstein Castle in Bavaria, and two cityscapes resembling Miami Beach and Hollywood, which appear only as screen backgrounds rather than unique game locations). Jack must fly around the screen to collect the bombs. Each screen uses a different configuration of platforms upon which Jack may run and jump. Eventually, the levels reoccur a number of times with increasing difficulty.
