Comments on Molecule: Logic Grid Puzzle for Android

★★★★★ Lauren · Jul 6, 2026
Really enjoying this game. It's a clever take on the classic board game Black Box and feels really well put together. It's easy to learn but takes a bit of thought to get good at, which makes it really satisfying when everything clicks. I also like that there's an Extreme Mode once you've mastered the basics, so there's still a challenge. Definitely worth downloading if you enjoy puzzle and deduction games.
★★★★★ Oliver McPhee · Jul 6, 2026
An addictive game. Definitely worth a couple of quid for the bigger grids!
