Fred Flintstone finds a treasure map during work in The Flintstones: King Rock Treasure Island . To find the treasure, he must solve seven levels with some ending in boss battles. These are traditional side-scrolling platform levels where Fred jumps over gaps and dodges enemies.
However, hitting an enemy does not kill them instantly but stuns them; a state where they can be used as stepping stones. Hitting them while they are stunned kills them, but they respawn when Fred walks back to their starting location or at special skulls. There are also power-ups to collect: most increase the points counter or refresh the life energy, but one allows Fred to ride his pet dinosaur Dino. This allows him to throw axes straight and jump higher, but Dino is lost when hit once.
