Eden's Quest is essentially a puzzle game similar to the ones in the Professor Layton series, where the objective is to solve a series of separate, self-contained challenges to complete the story. The player assumes the role of Eden Hunt, a famous world explorer that decides to fund her next expedition project by entering a mysterious competition for ten million dollars taking place on a remote island.
The puzzles can be accessed as totems scattered around the scenery, bringing up a screen split horizontally between a larger interactive portion at the left, with brief instructions and hints listed at the right side. Shining hotspots on the scenery contain coins, that can be collected and used to buy hints at the challenge screens. There are three levels of hints, each getting successively more explicit than the one before. The puzzles are varied, with mathematical questions, logic riddles, and in some instances mechanisms that have to be manipulated directly to solve them. Wrong guesses decrease the number of points received when finally getting the correct answer.
After solving each totem, the player receives a piece of a tangram puzzle, that must be assembled at the end of each chapter to open a new zone and continue the game. The gates to each part of the island are closed with a electronic lock, and must be opened by completing their own puzzle, where the objective is to move blocks inside a box to create an exit path for a circuitry piece.
