Find the hidden connections. Complete the groups. Reveal the Keystone. Keystone is a handcrafted word-link puzzle game built around one simple challenge: sort 16 words into four connected groups of four. Some links are obvious. Others hide behind double meanings, shared themes, wordplay, categories, or unexpected associations. Solve all four groups, then answer the final Keystone question that ties the puzzle together.
