Before I Start Posting About My Current Project…
Before I dive into what I’m currently working on, I want to share something I built late last winter, a small puzzle game called Tunnel Logic.
It started as a side project. Because I liked the escape game riddles in the advent calendar.
Tunnel Logic was created using React, Tailwind CSS, and Reddit’s Devvit framework, which allows games and apps to run directly inside Reddit. I wanted to see if I could build a clean, logic-based puzzle game that works instantly in the browser and feels good to play in short sessions.
In January, Tunnel Logic was actually featured on Reddit, which suddenly pushed the player count way up. At its peak during the feature, it reached close to 500 players per day.
After that wave settled, it stabilized at around 100 daily players, which it still holds today.
For a small puzzle game made as a side project… that feels pretty amazing.
How Tunnel Logic Works
The core idea is simple, but deceptively tricky.
You’re given a grid with an entrance and an exit.
Your goal is to draw a continuous tunnel path from start to finish.
Along the edges of the grid, you see numbers.
Each number tells you how many cells in that row or column must be part of the tunnel.
So if a row says “4”, exactly four cells in that row must be filled with tunnel pieces.
There’s no guessing involved.
Every puzzle can be solved using pure logic.
