A square next to a circle? A red triangle on the left? One of each color? There’s a secret rule to determine which sequences of 3 colored shapes are allowed and which are not. Using your powers of inductive logic, you must predict whether each new sequence fits. Collect evidence, adjust your predictions, and guess the rule–it’s a lot like the scientific method!

Guess the Rule is easy to learn but difficult to master. Start with simple rules, but if you want to spice things up, try double rules joined by “and” or “or”. You’ll find endless challenges, some of which are absolutely diabolical!

Play alone or with friends! Compete for daily high scores, or see who can guess the rule fastest in a pass-and-play match.

Amazing Game!

Simple but sleek UI and a genuinely challenging game come together for an extremely enjoyable experience. The scoring system is fun and is a good way to measure success without getting discouraged. I love puzzle games and haven’t found a game quite like this before or since!

Just as it says on the box

this game runs exactly as advertised, and it’s really fun to do in those idle moments. Except it’s not idle at all, it hurts my brain in the best ways and I’ve really enjoyed it.

A genuine challenge

It’s pretty difficult at times, ie, near impossible, but that’s cool. I enjoy the challenge.
