Nothing to install, nothing to pay
Every puzzle runs in the browser tab you already have open, on a phone, tablet or computer. There is no app store download, no account, no email address and no payment. The site is funded by advertising that only ever appears beside the puzzle, never on top of it.
Better than a printable sheet
A printed page gives you one puzzle and an answer key you can accidentally see. Here a wrong tap costs two seconds and a correct tap marks the spot in both scenes, so you always know exactly where you stand — and there is a fresh puzzle again tomorrow.
How a round plays
Two near-identical scenes appear, stacked on a phone and side by side on a wider screen. Tap anywhere you think something changed. Find every change to finish; beat the target time without hints for three stars. Most rounds take two to four minutes.
Your progress stays yours
Solved puzzles, best times and your daily streak are saved on your own device rather than in an account. That means nothing to log into, and nothing of yours stored on our side.
