K-affeine: Who Ordered This? is a cozy cafe simulation where you play a part-time barista at a Korean cafe — and the local guide for every flustered traveler stuck at the self-order kiosk. WHY KOREA'S KIOSKS? Korean cafes run on kiosks, abbreviations, and unwritten rules. 'Ah-ah'? 'Ah-shot-chu'? Locals order in seconds; visitors freeze. K-affeine turns that real moment into a game: you take orders, guide guests through the kiosk step by step, and craft their drinks before patience runs out. HOW IT PLAYS • 7-day story: from your first americano to a full menu of Korean cafe drinks • Kiosk helper quizzes: learn real ordering phrases and cafe slang (ice/hot, add-shot, ade vs iced tea) • Hands-on crafting: scoop ice, pull espresso shots, pour, steam, whip and top — every drink judged on accuracy • Queue pressure: serve the counter while the line behind grows impatient • Collection book: unlock recipe cards, practical Korea-travel tips, and a daily cafe diary • Store rating: earn reputation guest by guest and reach the five-star hanok badge LEARN REAL KOREAN CAFE CULTURE Every drink is a real Korean menu item — dalgona coffee, black-sesame latte, misugaru, mugwort latte, omija/maesil/yuja teas and ades. Every tip card is something you can actually use on a trip to Korea: skipping the loyalty-points screen, finding the Wi-Fi password, cafe etiquette and more. • Play offline — your cafe is always open • Korean/English bilingual: every line of dialogue in both languages • Sign in with Apple or Google to keep your progress across devices (optional — you can play as a guest) Made by Culturepresso for the KF Digital Public Diplomacy Academy.

Verdict
The clearest difference is in-app purchases: K at none against Factory 4.0's 11. K also leads on ads (none vs shown) and update cadence (every 2 days vs every 3 weeks). Factory 4.0's advantage is device support (3 vs 1). On price and iOS requirement there is nothing between them.
