what is Grid Forge TD?

Place tetromino shapes strategically to shape enemy paths in this incremental tower defense game.

Grid Forge TD is an incremental tower defense game where players position tetromino pieces to define the routes enemies take. The gameplay revolves around strategic placement to manage enemy movement.

It sits in the Strategy / Prototype corner of the genre. Like most idle games it runs on a simple loop — earn, reinvest, automate — but the depth is in how long that loop keeps unfolding. Expect to check in, make a few decisions, and watch the numbers climb whether you're at the keyboard or not.
