Frequently asked questions
Is SpotDiffMaker really free?+
Yes. The generator, online play, and printable worksheets are free with no sign-up. A Pro version with unlimited scenes, commercial license, and PDF export is coming — you can join the waitlist today.
How are the differences created?+
Every puzzle is generated by code: the engine recolors, moves, resizes, removes, or adds elements in the scene. Because each change is recorded, the answer key is always exact — no AI guessing.
Can I use the puzzles in my classroom or printable products?+
Personal and classroom use is free. If you sell printables or publish books (Etsy, KDP, TpT), you need the Pro commercial license — join the waitlist on the Pro page and we will notify you at launch.
Do I need an account to share a puzzle?+
No. Every puzzle gets a shareable link that encodes the scene and the differences. Anyone who opens it sees the exact same puzzle — no database, no login.
How do I print a puzzle?+
Click “Print / PDF” under any generated puzzle, or visit the Printables gallery. Your browser print dialog handles the rest, including “Save as PDF”. The answer key prints on the second page.
