Hello Patreons. There's a bit of a delay on solution videos for Duality III; these will be coming out at some point. In the meantime, Riffclown and Skunkworks have suggested we re-release Duality II - this was our Patreon reward in November 2024 - so everyone can have a go at it if they want more Duality puzzles, or to refresh their memories.

So here is that pack. Do enjoy these puzzles, and many thanks to the Skunkworks collective who created and tested them all.
