Matthew Brown logic puzzles

If you enjoy working through puzzles at your own pace, this collection from Matthew Brown gives you a clear place to start. Hexcells Infinite asks you to open safe spaces on hexagonal boards by interpreting nearby counts, and much of the set follows that same calm, step-by-step reasoning. Cypher moves you into code-breaking from a first-person view, while Sentinel pairs tower defense decisions with music that responds to your actions. You can settle into quiet grid logic first, then switch to ciphers or sound-based play when you want a different kind of challenge.
