The player plays as a dinosaur named Wagyan who is on a quest to save the people of Wagyan Land from Dr. Devil. The game is primarily a side-scrolling platforming game where Wagyan must avoid enemies and make it to the end of each stage. Most stages feature a boss at the end where Wagyan must defeat them in a card minigame in order to move on to the next stage. There are also hidden warps hidden throughout the stages that can transport Wagyan to a later stage. The game spawned several sequels including two other games for the Famicom, three games for the Super Famicom, one mobile game, and one game for the Nintendo DS (Platform).
Wagyan Land would eventually receive a Japan-only 2008 re-release on the Wii's Virtual Console.
