CountryChain
Read full descriptionHide full description
A geography chain battle. Connect countries that share a border. Start from one country — say France — then name a country that borders it, then a country bordering that one, and so on. If you can't name a connecting country, you lose. Corner your opponent into a dead end, or run out their clock, to win. ■ Three ways to play - vs CPU: play solo against the computer - Pass-and-play: share one device and take turns against the person next to you - Online: share a room code to play a friend in real time (no account or sign-in) ■ Features - A world map to check where each country is - Hint: peek at the countries you can connect to now (peeking spends your own time, so it stays fair) - Toggle the time limit and the map on or off - No ads, ever — nothing breaks the pace of a match ■ Premium (one-time purchase, optional) Want to play by your own rules? Unlock rule customization with a single one-time purchase (hint count, wrong-answer penalty, starting country, and more). You can still play every mode to the end for free.
