Türkiye, 1958. One photograph. Everyone in it is lying. In CASE No: 1958 you are the detective. A crime scene photo lies in front of you: zoom in, tap every suspicious detail, collect the evidence, question the suspects and find the killer. Nobody hands you the answer; you prove every conclusion with evidence from the photograph. From darkrooms and foggy docks to snowbound hotels and valleys of stone, the case files take you across a country caught between old secrets and a changing world. Every file brings a new place, a new circle of suspects and a lie hidden in the photograph. There is no rush; all you have to do is look closely. ■ HOW TO PLAY • Zoom into the photo and tap the clues. • Every underlined word goes into your notebook. • Question the suspects and catch the contradictions in their stories. • Fill in the solution notebook: Who? Where? When? Why? • Stuck? Ask your informant. ■ WHAT MAKES IT SPECIAL • A multi-season series of case files: every season has its own city, its own mystery and its own big secret that opens in the finale. • Handcrafted scenes: 1950s atmosphere in film noir light. • Fair play: every blank has exactly one answer and the clues are always in the photograph. No losing, no timers. • Solve cases and climb the ranks. • Home Screen and Lock Screen widgets, Apple Watch, Siri and Shortcuts support, none of them spoiling a thing. • Available in English, Turkish, German, Arabic, Russian, Spanish and Portuguese. • Calm and fair: clues are never locked behind a paywall. • No ads, no tracking, no account needed. New season: The Valley of Shadows, in Cappadocia. The file is on your desk, detective. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
