The mechanic has two layers: the shared grid, and the connected themes. Each day's two crosswords are thematically paired around a central idea. For example, a previous puzzle was "Same House, Different Kingdoms" - same home, same humans, entirely different worlds. One crossword is the dog's world, the other is the cat's. The themes are chosen to be related but distinct, which creates an extra layer of satisfaction when the connection clicks.
The constraint of forcing two crosswords into one physical space turns out to create genuinely interesting solving decisions - sometimes the two puzzles help each other, sometimes they fight.
Built solo over a few months using React, Python, Supabase, Fly.io and Resend. Three months of daily puzzles pre-loaded. Launched two weeks ago.
Would love feedback from anyone willing to try it.
