Triple (or maybe even quadruple?) threat Josh Collinsworth is back on the show to talk about his new game, Tupo. They cover how the puzzles are generated and kept fair, why the usual Sudoku pencil marks don't help, and what Josh's player data shows about hints and checks. They also get into the tech stack, why Josh skipped the app stores, and how daily puzzle games took off after Wordle.
