The KDP Domino Search maker
Generate a whole graded Domino Search book, then export it at every KDP trim, print-ready at 300 DPI. Make one puzzle free in your browser, unlock a full project for a one-time fee, and export unlimited formats forever.
$4.99 once per project. Unlimited exports, every trim. No subscription.
Every puzzle splits exactly one way
This is the hard part of the genre, not a given. Most layouts of a domino set can be split more than one way: measured across thousands, between one in forty and one in two hundred pins a single answer. The studio generates and checks until it has the ones that do, so no puzzle in the book has a printed answer that is merely one of several.
Every KDP trim, 300 DPI
Pick any of KDP's 17 trim sizes, from 5.06 by 7.81 up to 8.27 by 11.69, with correct margins and gutter. The single interior file you upload passes KDP review.
Generate once, export forever
One project unlocks for $4.99. After that, re-export any trim, any time. No monthly subscription and nothing to cancel.

Questions
- How much does it cost?
- A project unlocks for $4.99, paid once. After that you can export the interior and solutions PDFs at any KDP trim, as many formats as you like, forever. There is no subscription.
- What do I get when I export?
- One print-ready 300 DPI interior PDF, with the answers at the back, sized for the KDP trim you choose. That interior is the single file you upload to KDP. You also get a separate solutions PDF.
- Are the puzzles guaranteed to have one solution?
- Yes, and it is the thing to check when you compare domino books. Every puzzle is generated and checked so the pips fix exactly one partition before it enters the book, which most layouts of a set do not. The printed answer matches every puzzle.
- Does every puzzle print the checklist?
- Yes. Under each grid is a tick box for every piece of the set, with the pip values along the top and down the side. Knowing which pieces are already used is most of the solve, and a double-eight book asks a reader to track forty-five of them.
- Can I try it before I pay?
- Yes. The free Domino Search generator makes a real 2-page puzzle in your browser with no sign-up. The unlock is only for a full multi-puzzle project you plan to publish.
- Can I sell the books I make?
- Yes. The exported interiors are yours to publish and sell on Amazon KDP or print yourself. The per-project unlock covers unlimited exports of that project.
