LinguaCity is an idle city-builder for learning Serbian, Slovenian or Croatian. Unlock locations in your city and pick up vocabulary in context.

Important: this app is designed for Russian-speaking learners. The interface, theory and translations are in Russian; the target languages are Serbian, Slovenian and Croatian.

How it works
• A map of 20 city locations: market, bank, school, pharmacy, airport and more. Each one can be unlocked and upgraded through 5 levels.
• Every location has a themed vocabulary pool. You learn the words through exercises and earn coins for the next upgrade.
• The more buildings you open, the higher your passive income — come back any time to collect what's accumulated.

Exercise types
• Multiple-choice translation (4 options)
• Build a word from shuffled letters
• Match pairs (Russian ↔ target language)
• Build a phrase from word tiles
• Typing input with typo tolerance
• Blitz round: 60 seconds of swipe true / swipe false

Grammar — a separate track
Alongside the city, a dedicated grammar path covers 4 districts (CEFR A1 → B1), around 200 lessons in total. Each lesson includes theory with conjugation tables and audio examples, plus 2-3 simple tap-only exercises. No keyboard input is required.

Progress support
• Daily XP goal with 4 difficulty tempos (50 / 100 / 150 / 250 XP per day)
• Day streak with a freeze option
• Weekly and monthly challenges
• Achievements and mystery boxes
• Multiple profiles — share the app with family
• Kids mode: a separate location set, no ads, no in-app purchases

Languages available
• Serbian (sr-RS)
• Slovenian (sl-SI)
• Croatian (hr-HR)

Words, phrases, grammar lessons and TTS audio are provided for each language. You pick a target language per profile and can add another later without reinstalling.

Premium subscription unlocks
• Grammar series 4-7 (cases, tenses, syntax, B1 review)
• +50% income from all city locations
• Unlimited lives
• Ad-free experience for adult profiles

LinguaCity is for Russian speakers who want to learn a South Slavic language for everyday use — relocation, family ties, travel or interest — at a pace that adapts to them.
