SOLVI
Read full descriptionHide full description
What happens when Fire meets Water? Or Earth and Air? Drag two elements together in Solvi and see what they become. Then keep going. Every discovery adds something real to a floating island that grows and changes as you play: weather rolls in, day turns to night, seasons pass, and eventually people arrive and build a settlement that grows from a camp into a city, all from the elements you combine. There is no timer, no energy meter, and nothing that locks you out of playing. Come back once a day or once a week. The island keeps its answers the way you left them. WHAT YOU'LL DO - Combine elements freely to uncover 247 discoveries across Fundamentals, Nature, Materials, Reactions, Life, Civilization, and more - Watch your discoveries change the island itself: plants grow, weather happens, a settlement rises, animals move in - Solve a new Daily Mystery combination each day - Fill in the Codex and complete milestones as your island fills out - Explore nine islands, including the frozen coast of Frostreach and the mangrove waterways of Verdant Flats - Follow discovery clues with Your Journey and keep track of experiments in the Notebook - Try optional weekly recipe puzzles alongside the Daily Mystery Solvi is built to be picked up for two minutes or twenty, with nothing standing between you and the next discovery.
