Train track puzzles are taking off, and there’s plenty of room for you
You know those train track puzzle books popping up all over Amazon? Yeah. Connection Quest builds those, only better.
Puzzle fans are hooked on them. A grid, a few numbers, one railway line to find, and suddenly it’s midnight and they’re on puzzle 47.
Here’s the part that matters to your bank account. This niche is young. A couple of books are making real money, and most of the rest look exactly alike. That gap is your opening.
What the data says about train track puzzle books
These figures come from BookBeam, which estimates sales from Amazon best seller ranks. So you can check them yourself.
That’s the estimate for one self-published train track book that’s been live for about 2 months. Not a big publisher. A regular self-publisher who got in early.
Source: BookBeam estimated sales. Figures are estimates, not exact sales.
The top seller is self-published. No famous name, no publishing house.
And the rest? Most plain train track books sell a copy or 2 a day, if that. Same bare grids, same look, nothing that makes a reader remember them.
Readers clearly want these puzzles. They just want more than a blank grid. That’s exactly what your books give them.
Indie train track books selling on Amazon right now
No big ad budgets. No big publishers. Just regular self-publishers with train track puzzle books, and buyers picking them up every single day.
Estimated gross sales from BookBeam: copies sold per day x list price x 30. Estimates, not exact sales.
Look familiar? You can build books just like these, then go one better with numbered stops, a trip to plan on every page and 4 themes.
Beautiful puzzle pages, ready for Amazon on day one
Every puzzle gets its own page. A one-line trip tells readers where the train is going, a numbered key shows the stops, and the numbers sit along the top and side of the grid. A few pieces of track are already laid to get readers started.
The answer keys live in the back, with every track drawn in full, so readers can check their work. (Or peek. We don’t judge.)
Clean black and white pages, big friendly grids, nothing cramped. The kind of book people happily buy for themselves, their dad and their puzzle-mad neighbor.

Go on, solve a real Connection Quest puzzle
This is a real Easy puzzle made by the builder. Lay one railway line from the steam engine to the station clock, then on to the engine shed. The numbers tell you how many squares in each row and column the track uses.
The steam engine sets off: check the station clock, then head back to the engine shed.
Tap a square to start the track, then keep tapping to lay it. Check shows what’s right so far.
Fun, right? Now imagine a whole book of them with your name on the cover.
The puzzle they already love, with stops to call at in order
Here’s the special twist that makes your books stand out from the plain ones.
- 1Stops in order. Every puzzle has numbered picture stops along the line, like the steam engine, the signal box and the station. Readers have to call at every stop, in order.
- 2Dots show the way. Little dots beside each stop show where the track comes in and goes out. A smart extra clue readers love to use.
- 3A trip on every page. Each puzzle opens with one line that names the stops in order, like this real one:
The steam engine sets off: load the luggage, pick up the carriage, then stop at the platform, and pull into the station.
So they’re not just filling squares. They’re planning a trip. Suddenly a logic puzzle feels like a little adventure, and that’s what readers remember.
A How to Solve page in every book, and every book made your way
Every book comes with an illustrated How to Solve page: a worked example, the rules in 6 short steps, and pictures of corners, bridges and keep-out squares. Readers get it in one page and dive straight into puzzle 1.
And it’s all yours to customize. Rewrite the How to Solve wording and save your own versions, add a Puzzle Zero warm-up with its solved track on the next page, and put your title, author name and imprint on the front pages.
Four puzzle books in one builder, with exclusive themes you won’t find anywhere else
Switch the theme and you’ve got a whole new book, with its own pictures, stops, covers and readers.
Railway
Steam engines, signal boxes, coal towers and stations, with real rails drawn on the page. The classic train track look fans already buy.
Circuit Path
One wire runs from the solar panel through the sensor and the resistor to sound the speaker. Made for techy puzzlers.
Pipe Works
One pipe runs from the well pump to the sprinkler, the toilet and the sewer grate. Yes, there’s a rubber duck.
Construction Site
The crew visits the excavator, the cement bags and the new house in order. A natural fit for gift buyers.
See every theme on the page
Mix themes in one book, or give each theme its own series. Your call.
From first-timers to puzzle pros, one builder covers every reader
Closed Loops
The trip starts at the station and comes back to it. A fresh challenge in the Railway and Construction Site themes.
Keep Out Squares
Fallen trees, rock falls and closed barriers the track can never enter. Turn them on for a bigger brain workout.
Track Crossings
On Hard puzzles the line can cross over itself, but never turn on a crossing. Sneaky in the best way.
Mix levels in one book, or build a whole series that gets tougher book by book.
