Description
Crux 25 is the kind of brain‑teaser you can pull out of a drawer, solve in the time it takes to sip your coffee, and stash away again without ever spilling a single piece. Designed by Fritz Gruber in 2013, this ultra‑lean abstract strategy puzzle is built for one (or even no) players, so you can tinker with it whenever the mood strikes—no setup, no waiting, just a few minutes of pure, quiet fun. The rules are so simple you’ll have them down in a flash, but the challenge lies in spotting the hidden pattern that makes the whole thing click. It’s a tiny, educational puzzle that feels like a quick mental workout, perfect for a solo break or a clever little add‑on to a game night.
