Gridbinder · E-ink tablet PDFs

E-ink puzzle PDF maker for Kindle Scribe, reMarkable, Boox and Supernote

You want logic puzzles you can write on, or puzzle PDFs to sell on Etsy, Gumroad or Payhip to people who own an e-ink tablet. A paper layout does not fit: the page is the wrong shape and there is no way to jump around.

Choose the e-ink edition in the studio and pick your tablet. Gridbinder makes a PDF that taps through: a contents page of numbered tiles, one puzzle per page, and Contents and Solution buttons. The free sample has a watermark and needs no account.

12 puzzles with your settings, watermarked, no account. Full books from $9 a month.

Why the proof matters here

On an e-ink tablet the reader taps Solution and compares. If the puzzle has two solutions, or can only be finished by guessing, the buyer finds out there and then, and a one-star review follows. Every puzzle in the PDF is searched for a second solution and thrown away if one exists, and a step-by-step solver has to finish it too (two-star Star Battle is the exception: the search alone is its proof). The Verification report at the back of the PDF shows it, one line per puzzle.

Books end with a Verification report (on unless you switch it off): each puzzle with its level and size, the number of solutions a complete search found, and, for every type with a step-by-step solver, how it finished the puzzle.

Book ideas: A Sudoku and Killer Sudoku PDF for Kindle Scribe owners, sold on Etsy; A Slitherlink and Masyu PDF for reMarkable users, sold on Gumroad; A mixed logic puzzle pack for Boox or Supernote, sold on Payhip.

Questions

Which tablets does the e-ink edition cover?

There are presets for Kindle Scribe (opened with Send to Kindle), reMarkable 2 and Paper Pro, Boox Note Air, and Supernote A5 X and Manta. All use a 6.2 x 8.27 in page, and the presets differ in the room they leave for the tablet's own toolbar.

How does the tap-through PDF work?

A contents page shows numbered tiles for the puzzles, each with its type and level. Every puzzle page has Contents and Solution buttons, and every solution page has a button back to its puzzle. The Verification report is at the back.

Can I sell the PDFs, and is this a Kindle Scribe book for KDP?

You can sell the PDFs on Etsy, Gumroad, Payhip or your own site under the commercial licence that comes with the subscription ($9 a month or $69 a year). It is a PDF, not a KDP book: Kindle Scribe write-on books in the Kindle Store are not open to self-publishers, and we do not promise them. You may not resell the puzzles as a pack for other publishers.
