Conquest (1983)

Defeating pterodactyls is done by slamming into the pterodactyls (which bears no visual resemblance to actual pterodactyls) from a higher altitude; a lower altitude will result in death, while vertical altitude will result in the player and the pterodactyl bouncing off each other. Successfully slamming from a higher altitude will turn the pterodactyls into eggs, which may bounce away, as well as award the player with points. Additional points may be gathered by collecting these eggs. The game is divided into different rounds which will introduce more challenges: additional pterodactyls, which will spawn at any one of the eight green spawning areas; the lower ground will disappear and introduce wind current affecting the gravitational velocity of all moving objects in the game; the default six platforms may also change into fewer platforms; and an indestructible dragon may occasionally appear, resulting in instant death when collided with.
