Contents PlotLayton has received a letter from his apprentice, Luke Triton, from ten years in the future. Thus Layton and Luke take a trip to London to see the new Time Machine invention. While there they solve puzzles and take a trip to the future, meeting his Future Mom and helping to solve various strange mysteries in Future London, uncovering Layton's past and future.GameplayAs with the previous Professor Layton games, Unwound Future is an adventure game where the player solves puzzles offered by local citizens to progress the story forward, through dialogue and around 32 minutes of full motion video. The player moves about the game through still images of locations. The player can use the DS touchscreen to tap on non-player characters to start a dialog or to obtain a puzzle, and also can search anywhere on the background for hint Coins, with some areas needing to be tapped several times to reveal a secret hint coin or puzzle. Puzzles are brainteasers of many varieties, including visual, math, and logic. There is no time limit to solve puzzles, and the player can get up to 3 hints at a cost of one hint coin each; a new feature in Unwound Future is a 'super hint', costing 2 Coins, that can only be bought after the other 3 hints have been revealed, but that nearly reveals the puzzle's solution.

Professor Layton and the Unwound Future, known as Professor Layton and the Lost Future in Europe and Australia, is the third game in the Professor Layton series by LEVEL-5.It is the final game in the original Layton trilogy, and chronologically speaking is the last game overall.

If the player is correct in solving the puzzle, they gain a number of 'Picarats', a form of currency within the game. Guessing the incorrect answer will reduce the number of picarats the player can get on subsequent attempts. Players can visit certain areas in order to play undiscovered or unsolved puzzles that are left behind as the story progresses. As part of rewards for solving puzzles, the player may play one of three mini-games that support additional puzzles in Layton's Trunk that can be attempted at any time.

One mini-game is based on sticker books, placing the correct stickers at locations in the book to make the story make sense. Another requires training a parrot to carry items to a character using a series of ropes to act as perches or rebounding walls. The third mini-game is a toy car that the player must drive across specific tiles on a map using a series of directional indicators. Layton's Bag also contains details on the story, characters, and a list of completed puzzles the player can review and try again.After completing the game, several other puzzle challenges become available in the game's bonus features, many more difficult than the main game puzzles. When the player has completed all the puzzles within the game, a final puzzle is revealed. Players may also access a number of bonus features depending on how many picarats that have accumulated throughout the game.As with the previous two titles in the series, additional weekly puzzles were available for download via the Bonus menu, with one being released each week from the original release date, for 33 weeks.

After May 20, 2014, it's no longer possible to download the additional content, as the Nintendo Wi-Fi Connection service was terminated on that date.Puzzles.
