Bigram Tower

Inspiration

While exploring Reddit’s Developer Platform, I wanted to create something that:

This inspired Bigram-Tower, a game where players arrange shuffled words into bigram chains like:

"machine" → "learning" → "model"

The goal is to create a competitive, time-based puzzle that’s fun, challenging, and shareable on Reddit.

Bigram-Tower is a daily word puzzle game running directly inside Reddit.
Players:

The game is designed for quick, repeatable engagement, with new puzzles appearing daily to keep players coming back.

Daily Puzzles: A new word tower challenge every day
Theme-based: Each day, new tower with new theme
Speed-Based Scoring: The faster you build, the higher your score
Penalty for Mistakes: Incorrect placements add penalty time
Undo Last Move: Fix mistakes without restarting
Leaderboards: Compete with friends and other players
Help & Demo: Interactive tutorial for new users
Archive: Revisit past daily puzzles anytime
Runs Consistently on Reddit: The game works reliably on both mobile and desktop

The project uses Reddit’s Developer Platform (Devvit) combined with a modern web stack:

Frontend

Backend

The architecture ensures scalability and consistency, so puzzles and leaderboards work reliably for all users.
