Sprill the fox was sunbathing in his boat while sailing through the Bermuda
triangle, when he was abducted by aliens from the planet Akvtar. They force
him to search for the Poseidon pearl, an ancient artifact vital for the
survival of their planet, among the debris of sunken ships.

Sprill: The Mystery of the Bermuda Triangle is a hidden object game with
logic puzzles between each chapter. The objective is to find and click on all
the items from a list at the right side of the screen, on locations filled
with scattered objects, within a time limit.

The puzzles take place on a separate screen and are mechanical in nature,
where the player has to interact directly with devices on the scenery to gain
access to an object and move on with the game. Objects can be dragged and
dropped, buttons can be pushed, chains can be pulled and so on. There are no
instructions, but the player can use the hints to skip one of the necessary
actions, incurring a time penalty.

Hints are stored as question marks at the top of the list, and when used they
show the exact position of one of the required objects. Extra hints can be
found and collected as hidden question marks on the scenery.
