Put every book back where it belongs by following the clues.

Shelf Clues is a logic puzzle game where you combine clues about each book’s color, pattern, and position to figure out the correct arrangement on the bookshelf.

Select two books one after another to swap their positions.
Read the clues, work out where each book belongs, and satisfy every condition to complete the puzzle.

You’ll start with a simple bookshelf, but as you progress, more books, different shelf layouts, and increasingly complex combinations of clues will challenge your reasoning skills.

■ Follow the clues to find the right place for every book

Each puzzle includes a variety of clues.

Which shelf a certain book belongs on
Whether a book should be on the far left or far right
Which of two books should be farther to the left
Whether two books should be directly next to each other
Whether a certain book belongs between other books
Whether two books should be on the same shelf
Above and below relationships
The distance between books

At first, a single clue may be enough to find the answer. As the puzzles become more challenging, you’ll need to combine several clues to determine the correct arrangement.

Solve each condition one by one, and even the most complicated bookshelf will gradually begin to make sense.

■ Simple controls, deeper deduction

No complicated controls are required.

Select the book you want to move, then select another book to swap their positions.

Whenever you move a book, the number of currently satisfied clues is updated immediately, allowing you to see how each move changes the puzzle.

■ Check the clues only when you need them

The game screen is designed to keep your focus on the bookshelf itself.

Tap the clue button to view all clues for the current puzzle. Select an individual clue, and the books related to that clue will be highlighted briefly.

Even when the bookshelf becomes crowded, you can quickly identify which books a clue refers to and continue solving the puzzle.

■ Start with one shelf and work your way up

You’ll begin with a small bookshelf where you can learn the basic rules.

As you progress, you’ll encounter more books and multi-level bookshelves. Puzzles gradually evolve from simple left-and-right positioning into challenges that require you to consider the order and relationships between several books.

New rules are introduced step by step, so there’s no need to memorize everything from the beginning.

■ Endless bookshelf puzzles

There is no final level.

Each time you take on a new level, a new puzzle is generated according to the game’s rules, so there will always be another bookshelf waiting for you.

Rather than repeating the same puzzle, each level features different book arrangements and combinations of clues.

■ Take your time and think it through

Shelf Clues is more about observation and logical thinking than quick reactions.
