About the Nintendo Entertainment System Adventures of Dino Riki Pre-Owned Cartridge Only

Adventures of Dino Riki is a scrolling shooter where the player takes on the role of the titular, primitive human Dino Riki in a prehistoric setting with dinosaurs. Each stage scrolls vertically with the objective being to avoid enemies and their projectiles then to defeat the boss at its end. Dino Riki can move in all directions, jump, and throw weapons to destroy enemies and uncover health and power-ups from boulders strewn about the landscape. These power-ups include speed boosts, wings that enable flight, and enhanced weapons. The player begins with rocks which can be upgraded to stone axes, then boomerangs, and finally torches, each consecutively improving range and spread of attack. A hidden item tile will transform the player into Macho Riki who can fire powerful projections of himself.

The game has four stages with the last of these consisting of four sub-stages. Some stages contain environmental hazards. For instance, the first features platforming sections with a bodies of water and lilypads that the player must jump or fly across. Some lilypads move back and forth while others submerge then resurface. Falling into the water results in instant death. Taking a hit from an enemy will drop speed and weapon upgrades down one level while dying will remove all power-ups and bring the player back to specific checkpoints.
