Stuck on a jigsaw piece? Puzzle Pointer is a jigsaw puzzle solver for the puzzle on your table: snap a photo of the piece and it shows you where to try it on your puzzle's picture, best match first, with the piece turned to match the spot. When puzzlers rate a search, 8 in 10 say the piece fit one of the spots it showed. FOR THE PIECE YOU CAN'T PLACE Sky, water, a busy 1000-piece scene, or one piece you've tried everywhere: Puzzle Pointer narrows a whole puzzle down to a few spots to try. It's for adults and families doing real cardboard puzzles, and for anyone who loves puzzling but not the frustration. FIND YOUR PUZZLE IN SECONDS Scan the barcode on the box: over 10,000 puzzles are ready to go, from Ravensburger, Buffalo Games, Galison, White Mountain, Springbok, Cobble Hill and more. Not in the catalogue? Photograph the box front or search by name. HOW IT WORKS 1. Find your puzzle by barcode, box photo or name. 2. Photograph one loose piece. The camera takes the shot when the piece is sharp and whole. 3. See the best spots to try it, ringed on your puzzle picture, with your piece beside each one, turned the right way. 4. Did it fit? Tap yes, or move to the next spot. WHY PEOPLE USE IT • No ads, ever. • No account or sign-up needed. • Works with the puzzle you already own: no need to photograph the finished picture yourself. • Honest when a piece is hard: plain sky or single-colour pieces get a heads-up before you use a search. • Your puzzles and placed pieces stay saved, so you can pick up where you left off. • Private: your photos are never public, and "Delete my photos & data" in the app removes them. • Share a found piece as a picture card. Some pieces, like plain sky or water, look alike in many places, so you check the fit yourself and move to the next spot if it's not right. FREE TO TRY Up to 10 piece searches free: your first 5 are free, and if a free search's spots don't fit, you get another try. Then buy 10 searches for $2.99 (no subscription), or get unlimited searches with Puzzle Pointer Monthly for $6.99 per month. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel it in your Apple Account settings. Prices may vary by region.
