What is Plotting: Definition and 558 Discussions

Plotting is a tile-matching puzzle video game published by Taito in 1989. It is called Flipull (フリップル, Furippuru) in Japan as well as in versions for the Famicom and Game Boy, and Plotting in versions for the Atari ST, Amiga, Commodore 64, Amstrad CPC, GX4000 and ZX Spectrum. All are based on an arcade game which is known as Flipull (フリップル, Furippuru) in Japan and Plotting elsewhere. The game bears strong graphical and some gameplay similarities to Puzznic.
