How to play
Play Blueprint Spotter free online
Blueprint Spotter is a free online spot-the-difference game with two technical drawings, an original above and a revised copy below. Find every planted difference by tapping on either sheet, from one up to six per stage. Wrong taps fill marks, and flawless sheets earn marks back. It plays in the browser on phone or computer, with no sign-in needed. Ten stages make a block, and your progress is kept so you resume where you stopped.
How to play Blueprint Spotter
- Two blueprints sit one above the other. Tap every difference you find, on either sheet. Shapes can move, change colour, grow, shrink, turn, vanish or appear.
- A wrong tap fills one of your 3 X marks, and 3 marks end the run. Clear 3 sheets in a row without a wrong tap and you win a mark back.
- Stuck? The magnifier circles an area that holds a difference. You get 2 free per run.
Blueprint Spotter tips
- Compare the sheets in small zones, such as corners and edges, rather than trying to take it all in at once.
- Three flawless sheets in a row win back a mark, so accuracy beats speed.
- Use the lens hint only when stuck, because it breaks your flawless streak.
Blueprint Spotter questions
- How many differences are there?
- One on the first sheets, then more as you climb, up to six. The time bar grows with the count, and the sheets get busier and the changes smaller every 5 stages.
- Do I have to tap the top or the bottom sheet?
- Either. Both sheets share one frame, so a tap on a spot counts on the top sheet or the bottom one.
- Where does a new run start?
- Your furthest stage is saved. A new run starts at the first stage of its block of ten (1, 11, 21 and so on).
