In Spelunker - which means 'cave-diver' - a caver has to work his way down through a number of multi-directionally scrolling caves - each one deeper underground than the last - in his bid to find the mythical 'World of Wonders'. To do this, the spelunker must find the exit to each cave, so he can move on to the next and get closer to his goal.
Spelunker is a platform game, and each tricky cave is filled with enemies - such as bats and ogres - and traps. Ladders, ropes, lifts and the obligatory minecarts must be used to reach other platforms and sections of the cave.
To aid him in his difficult quest, the Spelunker carries a gun and can shoot short-range fireballs at his enemies to stun or kill them. Numerous bonus items can be collected, such as bombs to destroy any rocks block his route, keys to open locked doors and potions to boost the caver's ever-decreasing energy meter. Treasure chests also litter each cave, and can be opened for bonus treasure items.
