How to play
Master the map.
Map Jigsaw
Build every real land neighbor around the glowing anchor country. Select a silhouette, then tap or drag it roughly to the correct compass side. There are no slots or hidden map clues. Easy and medium show names; hard hides them until placed. A broad direction hint unlocks after two misses.
Capitals & Cities
In Capitals mode, a country is shown: choose or type its capital. In Cities mode, a major city is shown: identify its country. All uses every available city, not just one city per country. With the optional timer on, faster answers earn bonus points. Existing challenges created before this update retain their original country-to-city questions.
Geo Grid
Each cell combines its row clue and column clue. Select a cell, search the full country atlas and submit one country that matches both. Countries cannot be reused. Fill all nine cells to solve the board; wrong entries cost a life outside Practice mode. The seed in the URL recreates the same board.
Geo Minesweeper
Countries form a network using their real land borders. Revealed safe countries show how many connected neighbours have the hidden property. Switch explicitly between Reveal and Mark, place exactly the available number of marks, then check them. A mine reveal or incorrect check costs one life. Easy shows the exact property, Medium shows only its family, and Hard keeps it classified until the end. Only correctly solved mine countries enter your Geo-Dex.
Color the Flag
A blank flag is shown. In Swatch mode pick the correct colour for each highlighted area from four options (you have three lives). In Pro mode, match the exact shade with a colour picker — the closer you get, the more points. Stripes, crosses and simple symbols (like stars) are all fillable areas; flags with intricate crests are left out.
Flag Pie
The donut shows the actual measured color shares of a flag. Choose which of the four flags matches; look-alike color distributions are never offered together. The complete, unaltered flag appears after your answer. Every planned round is played, with no lives. With the optional 20-second timer, faster correct answers earn more points.
City Compass
A city is hidden in the center. Named reference cities appear in their compass direction FROM that hidden city: Paris above the center means the answer is SOUTH of Paris. The spokes show direction, not distance. Exactly one of the four candidate cities fits every clue; choose it or type its name. There are 3–5 clues by difficulty. A geographic map and the country appear after answering. The optional timer allows 35 seconds per round.
Flag Mosaic
Identify a flag through a few uncovered tiles. Tap a numbered tile, or choose how many more tiles to reveal. Every extra tile reduces the available points, displayed above the flag. All tiles use the exact, correctly proportioned flag artwork. Choose or type the country; the whole flag is revealed after answering. Difficulty sets 4, 3 or 2 starting tiles. The optional timer allows 40 seconds per round.
Country Radar
Guess countries by searching their English or German names, or select one on the neutral world map and confirm. After each guess, the distance and arrow point FROM your guessed country's center TOWARD the hidden country's center. Warmer colors mean closer. Easy gives a continent clue and 8 guesses; medium gives 6, hard 4. Repeated guesses do not count. Fewer guesses earn more points. Solve the country or use every guess to reveal the answer, flag and map highlight, then continue to the next round.
Adastra
Study authentic NASA astronaut photographs at night. Rounds mix cities, metro areas or urban corridors, and regions; the label above each photograph tells you which kind to name. Urban corridors include neighboring cities connected by roads and smaller settlements, not only formally defined metropolitan areas. Zoom into street grids, coastlines, satellite towns and the roads connecting their light clusters. For broader areas, identify the larger network—not an individual small town. Choose an answer or type the area’s name. Easy starts with a regional hint and more distinct choices. Medium and Hard offer optional hints, with closer look-alikes on Hard. Each requested hint subtracts 25% of the round’s original base points, up to 50% in total; the free Easy region hint has no cost. Photographs may be rotated, so the top is not necessarily north. There is no timer and every configured round is played. The answer reveals the place, an explanation and the original NASA record. Idea by Adastra1995.
Atlas Match
Turn over two cards and match a flag to its country on Easy, or to its capital on Medium and Hard. Correct pairs stay open. If two cards do not match, choose ‘Turn these back’ when you are ready. A clean match earns 1,000 points; mistakes involving that country reduce its reward, down to 200. Collect all pairs and continue to the next board. Countries never repeat within a run. There is no timer and no lives to lose. Accuracy compares matched pairs with all turns.
Geo Balance
Choose exactly three countries from a hand of eight. Their combined population or area should be as close as possible to the visible target. Values remain hidden until you lock in your coalition. Easy accepts a 20% deviation, Medium 12%, Hard 7%. Successful rounds earn 300–1,000 points according to closeness; rounds outside the window earn zero. After every answer you see every value and the closest possible combination. Values are estimates from the GeoNerds dataset, not live statistics. Every target has an achievable three-country solution.
