As 2023 draws to a close—and as we start to finalize our Game of the Year contenders—I really should be catching up on the embarrassingly long list of great recent releases that I haven’t put enough time into this year. Instead, over the last few days, I’ve found myself once again hooked on a simple, addictive, and utterly unique Japanese Windows freeware game from the late ’90s that, until recently, I thought I had lost forever.

Pendulumania is a cult classic in the truest sense of the word: Few people have heard of it, even in hardcore gaming circles, but those who have experienced it tend to have very fond memories of it. And while I shared those memories, it wasn’t until this week that I’ve been able to share my effusive praise for a game whose name and playable executable had eluded me for well over a decade.

Timeless design

The mechanics of Pendulumania are incredibly simple. You use the computer mouse to control a metal ring, which is attached via an elastic string to a white ball. The object is to carefully move the ring so the stretchy string and gravity can nudge the ball around a 2D plane, crashing into floating scoring orbs to collect points (colored orbs that randomly appear can make the ball larger or the string stronger as well). Be careful, though; if the elastic string stretches too far, it will break and your game will be over.
