Some fun things I’ve made:

engine-game.com. Deckbuilding puzzle game with daily challenges.

Anagrams and Double Anagrams. Word jumble game.

Asymptotic analysis. A mystery-hunt style Dominion puzzle. [Collaboration with Vee Xing.]

reciprocity.io. Social network and matchmaking site with surprising uptake. [The original was a collaboration with Katja Grace and Stephanie Zolayvar but is now bitrotten from FB API updates. Buck Shlegeris remade it in 2021 and now maintains it.]
