Give Your Catalog a Puzzle the Other Books Do Not Have
Most logic puzzle books recycle the same three or four puzzle types, so on a crowded shelf they all blur together. Galaxies (also known as Tentai Show) is the fresh one that still reads in seconds: divide the grid into regions, one around each dot, so that every region is perfectly symmetric around its dot. It needs no arithmetic, it looks nothing like another grid of numbers or letters, and it gives a browser a reason to stop and try one.
Then comes the twist that makes one module do the work of two. Every dot can be a picture instead of a plain circle, so the same generator produces a sharp symmetry challenge for adults and a friendly “give every animal its own space” activity for children. You generate the puzzles and their guaranteed single solutions, ready to print and publish. See finished puzzles and their answer keys in the gallery above.
Why Galaxies Earns a Place in Your Catalog
Galaxies gives you a fresh puzzle that still feels instantly approachable: split the board so each dot sits at the exact center of its own symmetric region. The “find the symmetry” rhythm feels nothing like sudoku or word logic, which is exactly what makes a mixed book feel varied instead of repetitive, and a standalone book feel new.
It is a long-running favorite in Japan under the name Tentai Show and still fresh across many English-language markets, so it works as a headline title and as standout variety inside a larger collection. You are not betting on an unknown. You are bringing a proven puzzle to an audience that has not been served it yet. And because every puzzle is generated with one guaranteed, logic-only solution, what you publish is always fair.
I nearly left Galaxies off the list. I knew it had a following in Japan, but I was not sure an English-language audience would pick it up. Then I ran the first picture-dot batch for a children’s book and watched the whole set come together in an afternoon. The gap in the market turned out to be the point: you are not competing with fifty books that look exactly like yours.
See the Output
The fastest way to judge a puzzle is to look at it, so the gallery shows real output: a finished board, its matching solution with the symmetric regions shaded, the size and difficulty range, and the picture-dot styles that set this module apart.
Prefer to try before you trust it? Every Puzzle Maker Pro module includes a free demo, so you can generate Galaxies puzzles yourself and see the output quality, including the picture-dot styles, before you spend anything.

Theme It with Pictures, Not Just Dots
You publish a logic book, and then you want one for younger solvers or a seasonal gift market — without starting a new module from scratch. Swap the plain dots for images, from built-in sets such as Kids Animals to your own artwork, and the same symmetric-region puzzle becomes a children’s or novelty product without changing a single rule. One module, two shelves.
You control how the pictures are used. Set images per puzzle to one and every region on a page shares a single picture, so one page is all dogs and the next is all cats. Set it higher and several pictures mix within each puzzle. An optional numbered-dot mode adds a small number to every region, which makes answer keys clear and helps younger solvers follow along.
And your theme is not limited to print. With Productivity Edition the pictures travel into the interactive web output too, so a themed board plays online as the same picture puzzle, not a grid of plain dots. The animal book you print and the animal puzzle solvers play on your site come from one setup.
Puzzles You Can Publish Without Worrying
Building valid Galaxies layouts by hand is slow and easy to get wrong, because every region has to be perfectly symmetric around its dot and the whole board has to have exactly one answer. Solvability complaints are the fastest route to a bad review and a refund, and this is exactly where Puzzle Maker Pro removes the risk. It generates the puzzle and its solution together, guarantees that single answer, and ships every puzzle with its matching answer key in the same pass. What you publish is always fair, and you never hand-check a grid.
From a Gentle 7×7 to an Unreasonable Challenge
Your readers are not all at the same level, and neither are your books. Galaxies scales from a 7×7 grid that a newcomer solves in minutes to a 15×15 Unreasonable board that gives an experienced puzzler a real workout. Set rows and columns independently for any page format, add the numbered-dot mode for answer-key and easier versions, and one module covers everything from a children’s activity to an expert challenge without a second generator.
From One Puzzle to a Full Book
A single puzzle is a page. A full book of unique, consistent Galaxies puzzles — at the right sizes and difficulty mix, each with a matching answer key — is a product you can sell. Productivity Edition closes that gap: Time Saver generates the full set from one saved setup, and Puzzle Book Studio assembles them, alongside your other Puzzle Maker Pro puzzle types, into finished books and mixed collections. You set the look, theme, and difficulty once, then the workflow produces the pages.
And the everyday styling is just as quick. Set the canvas color, grid lines, region outlines, and dot style once, then reuse that look across an entire set so your collection looks designed rather than rebuilt page by page.
Choose Your Edition
Both editions create and export real Galaxies puzzles with matching solutions, including picture-themed ones. The difference is scale and digital output.

Who This Is For
Puzzle book publishers and POD sellers. Differentiate a crowded shelf with a puzzle type your competitors are not using, then turn one setup into a full book of unique, guess-free puzzles ready for KDP or print-on-demand. The picture-dot option opens a second shelf in children’s and novelty puzzles from the same module.
Existing Puzzle Maker Pro customers. Add a new logic type to the workflow you already know. Style it with your shared settings, batch it with Time Saver, and combine it in mixed puzzle books, with nothing new to learn.
Educators and parents. Build logical-reasoning activities sized to your students, from a gentle 7×7 to a tougher Unreasonable challenge. Picture dots and numbered dots make the puzzle approachable for younger children, so one module covers both the classroom and the kitchen table. With Productivity Edition you can also publish an interactive web version for screens.

Questions Before You Buy
Will my audience actually want Galaxies?
It is a long-running favorite in Japan as Tentai Show and still uncommon in many English-language markets, so it reads as both familiar and fresh. It also works as variety inside a mixed logic book, so you can introduce it without betting a whole title on it. And the picture-dot option lets the same puzzle reach a second audience in children’s and novelty books.
Are the puzzles really solvable and fair?
Yes. Every puzzle is generated with exactly one guaranteed solution, reachable by logic alone, and each one ships with its matching answer key in the same pass. You never have to hand-check a board.
Is there a free demo?
Yes. Every Puzzle Maker Pro module includes a free demo, so you can try Galaxies and see the output, including the picture dots, before buying.
What is a Galaxies puzzle?
A logic puzzle, also called Tentai Show, where you divide the grid into regions so that each region contains exactly one dot and is perfectly symmetric around it. No arithmetic is involved.
Can I use pictures instead of dots?
Yes. You can replace the dots with images from built-in sets or your own files, and choose how many images appear per puzzle, which is ideal for children’s and themed books.
Which edition do I need?
Choose Creative to create and export puzzles, including picture-themed ones, for pages, worksheets, and smaller collections. Choose Productivity for batch creation, Time Saver, HTML interactive output, JSON, and full-book assembly in Puzzle Book Studio.
Can I create a full puzzle book quickly?
Yes, with Productivity Edition. Time Saver generates large sets of unique puzzles from one saved setup, and Puzzle Book Studio assembles them into books.
Can I adjust the difficulty?
Yes. Grids run from 7×7 to 15×15, with two levels, Normal and Unreasonable, and an optional numbered-dot mode for easier and answer-key versions.
Can I use the puzzles in books I sell?
Yes, you can always sell your puzzles and puzzle books on Etsy or Amazon KDP (POD). To resell puzzles and puzzle books, you need the Productivity Edition.
Does it have interactive or web output?
Yes, with Productivity Edition. Export HTML to host yourself, or upload the ZIP to the BookPublisherTools WordPress plugin for interactive play, which is a simple way to draw solvers to your own site. If you themed the dots with pictures, those pictures carry into the interactive version too, so a kids or novelty set stays themed on screen. Puzzle Slides and Interactive PDF are not available for this module.
Add the Symmetry Puzzle Your Catalog Is Missing
Picture your catalog six months from now: a standalone Galaxies title that looks nothing like the fifty logic books beside it on Amazon, a picture-dot children’s version on the same shelf, and a mixed book where Galaxies is the puzzle readers flip back to. That is what one afternoon of setup produces.
Without a puzzle that stands apart, every new book you publish competes on thumbnail size and price with titles that look exactly like yours. Galaxies is the one that does not.
Try the free demo. Generate a few boards, explore the picture-dot styles, and see the output quality for yourself before you choose an edition.
