The game consists of four levels of platforms. Via stone ladders, players can climb up to and jump down between gaps in the four platforms (the player can climb down the ladders, but by using the "jump" button, the player will fall down the length of any ladder he is presently climbing; this trick enables the player to descend to the lower platform more rapidly). The bottom platform is continuous with no gaps. The screen is wrap-around: Exiting on one side, the player will enter on the other side of the screen. After collecting one or more eggs and/or detaining one or more Baby Dinos in force fields, the player may "warp out" by delivering the Baby Dinos back to the future. The player will then return to a different location on the same level, and attempt to save more eggs and Baby Dino hatchlings.
