Shellkeep is a merge isle defence game. Build barracks, archery towers, spires, stables and mines on your island, drag matching buildings together to merge them into stronger ones, and hold your castle against ten waves. Three difficulty levels and best-wave records keep you coming back.

Shellkeep is a free idle & strategy game you can play in your browser on Arcadily, on desktop or mobile, with no download needed.

How to play

Tap an empty plot to build. Drag a building onto its twin to merge them into a higher level. Press GO to start the next wave early. Mines earn extra gold between waves.
