*** The companion app to the board game Scotland Yard Master for 2–6 players, ages 10 and up (can only be used in conjunction with the board game!) *** IMPORTANT: The board game itself is not available in English! As many fans have imported the board game we’ve included the English language into the app as a fan service. Enjoy! Scotland Yard Master is the new development in the world-famous classic board game Scotland Yard, which was named Game of the Year in 1983. Together with the board game, this app offers a completely new and even more exciting way to play. The detectives are on the cutting edge of technology and even hotter on the heels of Mr X. They will find all the important information in the digital control centre: Which modes of transport has Mr X travelled by so far? When will he show himself again? What special actions can be used? You can select mobile phone tracking, for example, and point the smartphone or tablet’s camera at the four radio masts on the game board. Green, yellow or red radio waves will indicate whether or not Mr X is nearby. You can also question witnesses at important buildings across the city. The camera comes into play again, showing Tower Bridge, the Houses of Parliament and St Paul’s Cathedral in 3D. Witnesses will reveal whether Mr X is or has recently been there. Furthermore, the detectives can determine his possible locations by analysing his previous moves, or by measuring the distance between Mr X and the nearest radio mast. But if you think you’ve already got Mr X in the bag, you can think again. With his new escape option, the helicopter, he’s as cunning as ever. He can also win the game by reaching two of five pre-determined rendezvous points. The innovative combination of the classic board game and digital gaming fun guarantees an engrossing experience for the whole family!

About

RadMap

Live ambient radiation readings, on one map. RadMap gathers open data from Korea's national monitoring network (IERNet, operated by KINS), Japan's national network (RAMIS, operated by the Nuclear Regulation Authority), France's Téléray network (operated by ASNR, the French nuclear safety and radiation protection authority), and the Safecast citizen sensor network, and shows the current ambient gamma dose rate. WHAT YOU CAN SEE - Live readings from roughly 490 official Korean monitoring posts - Japan's official network across all 47 prefectures, plus the dense grid around nuclear facilities - France's official Téléray network: about 450 stations across mainland France, its overseas territories and around nuclear sites, updated every 15 minutes - Safecast citizen sensors worldwide - Map, list and per-station detail, with the trend over time BUILT SO THE NUMBERS CAN BE READ - Every dose band carries a text label such as "Normal" or "Slightly high" alongside its colour. Colour is never the only signal. - Readings are compared to familiar amounts: one X-ray, one flight, a year of natural background. - Where many stations overlap, they are grouped and shown as an average dose. - All figures use tabular figures, so the layout never shifts as a value changes. WHAT THIS APP PROMISES - The summary at the top of the screen covers Korea. It is calculated from the live readings of official Korean stations, never a pre-written sentence. If any of them rises above its normal band, it becomes an alert. - Every reading carries a provenance badge. Government networks and citizen sensors are never blended together. - Citizen sensors are not cross-calibrated, so they are never used to judge the picture across Korea. - No ads are shown while any official station is above its normal band. PLEASE NOTE This is an unofficial app that presents publicly available data in a readable form. Do not rely on it for official announcements or emergency decisions; for official information, please consult the relevant regulator. Available in Korean, English, Japanese and French.
