SPECTRA: Spot the Difference
Hidden Object Picture Puzzles
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
50 picture puzzles set across 5 storybook worlds. Optimized for iPhone Duo. Play levels 1–6 for free, then unlock everything with a single purchase. No ads, no subscr.
Two pictures, a few tiny changes – can you spot them all? SPECTRA brings spot-the-difference and hidden-object puzzles together in detailed storybook scenes, made for the whole family.
TWO WAYS TO PLAY
• Spot the Difference: compare two pictures and tap every change – a missing flag, a new color, an extra bird.
• Hidden Objects: find all 7 horseshoes in the Wild West town, or tick off everything on the search list in the library.
• Both modes take turns, so every level feels fresh.
50 LEVELS IN 5 WORLDS
Watercolor, comic, miniature world and clay: each world has its own look and ten scenes to explore – from the market square and the knights' castle to the pirate ship, the space station, the dino museum and the magic school. 336 things to find in total.
MADE FOR YOUR DEVICE
• iPhone: one large picture with a swipe divider – or blink between the two pictures. Switch the compare mode anytime.
• iPad: both pictures side by side, with plenty of room for the search list.
• iPhone Duo: unfold it and play like a puzzle book – one picture on each page, the fold stays free. Hidden objects: the scene on the left, a big search page on the right.
PLAY YOUR WAY
• Pinch to zoom – both pictures zoom together
• Stuck? A hint shows you where to look
• Earn up to three stars – each wrong tap adds 5 seconds
• Large tap areas, easy for children too
FAIR AND CALM
• Levels 1–6 are free
• Unlock all 50 levels with a single one-time purchase – no subscription
