Visual Memory Training vs Sprawl Crawl

Improve your visual memory skills Practice this brain exercise on your iPhone and on your Apple Watch (NEW!!!) Observe a sequence of numbers that are shown for a few seconds and reproduce it after the numbers disappear. How many sequences in a row will you be able to reproduce ? 5 levels of difficulty, from very easy to expert mode

Every round shows you a real satellite image of a city. No labels, no names, no borders. Just streets, rivers, coastlines and the shape a million lives make from 780 km up. Your job: name the city. Type the answer for full points, or reveal five choices for half. Ten rounds, one score. Smaller cities are worth more, so the deep cuts are where the big scores live. PLAY THE WHOLE PLANET, OR ONE CORNER OF IT More than 11,000 cities across five difficulty levels, from world capitals down to towns of ten thousand people. Play the whole world, a continent, a region, or drill into a single country. Every setting has its own global leaderboard. CHALLENGE YOUR FRIENDS Finished a round? Send it as a link. Your friends get the exact same ten cities, and everyone lands on one small scoreboard. No app needed on their side - the link works in any browser. SPECIAL QUIZZES Themed editions drop regularly: cities above the clouds, ports the cruise ships love, the far north, football's home grounds. Ten hand-picked cities each, with a hint to argue with. LEARN SOMETHING EVERY ROUND Thousands of cities carry a hand-written fact on the reveal - the mine that built the town, the river that named it, the derby that splits it. Sign-in is optional and passwordless (one email, a 6-digit code) - you only need it to put your name on the leaderboards. Imagery: ESA WorldCover Sentinel-2 (2021).
