Entirely. One version, nothing inside to purchase.
Can I win money or prizes?
No. Nothing in One Stroke can be exchanged for money or goods. Solved sheets are just solved sheets.
I get stuck on the lattice every time.
Count the lines leaving each dot. If more than two dots have an odd count, that figure cannot be done in one stroke — and I do not ship impossible ones, so look again.
How does the emailed build work?
Leave an address, pick Windows or Android, and I send the link by hand. One email. No list, no follow-ups.
Why 18 and over?
Because I hold those addresses briefly, and I would rather not hold children's. The puzzles themselves suit any age.
Will there be more sheets?
Forty in the packaged build. I add a few whenever a class of them turns out interesting.
Something is broken.
Tell me on the contact page — include the browser, the dots are fussy on old Safari.
