SunkenRuins

SunkenRuins is a casual underwater civilization game where you rebuild a lost empire beneath the waves — gather materials, construct and upgrade houses across ten tiers, earn passive income, and expand your drowned city block by block. Boost your progress in the Shop with sonar relays, drone nets, and archive contracts, then jump into quick mini-games like Find Pair, Fill Sequence, and Bomb or Not to earn coins and XP, or test your knowledge in the Ruins Quiz. Discover artifact lore in the Facts library, track ten achievements on your path to mastery, claim daily bonuses, and customize your experience with DeepSpirit modes — all wrapped in a calm ocean-themed adventure built for short, satisfying sessions.
