Metro Run
Read full descriptionHide full description
Metro Run is a typing game where you drive the train by typing real subway station names. Run a line on your own from end to end, or race other drivers live. Real lines around the world Ride the metro in 31 areas across 11 countries, including Seoul, Busan, Tokyo, Osaka, Taipei, London, Paris, Berlin, Barcelona, Madrid, Milan, New York, Chicago, Mexico City and Singapore. Maps use real station locations, drawn in a simplified style. Ways to play • Line mode: pick a line and course, then type each station from the first stop to the last. Can't decide? Try a random line. • Navigator mode: type the name of the next station to move one stop at a time, changing lines to reach your destination. Choose one or three destinations, a 1- or 3-minute time attack, or endless mode, which ends after three mistakes. • Battle: start on the same map as other drivers and win by arriving first. Bots fill in when there aren't enough players. • Friendly match: open a room and invite friends with a six-digit code or link. Up to 8 players, with practice bots and chat. Friendly results don't count toward rankings. Pick your typing language Type each line in its local language or in English (lines in the UK, US and Singapore are English only). Skip spaces and punctuation, and don't worry about capital letters. Records and rankings After every run you get your time, accuracy and characters per minute. Check the top 20 for each course, overall rankings by country, and the navigator and battle leaderboards. Collect trains Earn gems by finishing runs and spinning the roulette, then use them to get random trains. Trains with abilities can be merged to raise their star level, and the train you equip shows up next to your name on the leaderboards. Members can buy and sell trains in the market or send them as gifts. Start as a guest; if you sign up later, your records come with you.
