Duolingo Streak Mechanic
I played Wordle every day until I broke my streak once. Never went back. Duolingo runs on the exact same mechanic — daily streak, loss aversion, the whole loop — but with one difference: a freeze that absorbs the miss. I modeled what that buffer actually does to the system.
Been wanting to try Machinations for a while. Gamification mechanics — streaks, loss aversion, habit loops — show up in almost every consumer app now. The Duolingo streak felt like a good first thing to model: simple enough to be legible, interesting enough to actually think about.
Without the freeze, one missed day collapses the whole system. With it, the loop survives real life.
Streaks run on loss aversion, not motivation. Users aren't pushing the streak forward — they're protecting it from collapse. A streak that can't be repaired is a bomb set for a bad day. The freeze isn't a convenience feature. It's structural infrastructure that keeps the loop from being too fragile to survive real life.
