Before you jump in

The solo game opens on Decka and needs no sign-up, installation or extra game files. Each run deals seven new prompts, and you can replay without a daily limit. Rarer accepted answers take you deeper through the ocean or underground world. Best depth is stored in this browser separately for Dive and Dig. The game is in English; changing this guide’s language does not translate it. Decka also offers a separate live group version with a free host account, where matching answers reduce depth. This listing covers the solo Play entry.
