Molecule Maker is a relaxing puzzle game that lets you play with chemistry—no lab coat required. Swipe your way through a honeycomb grid, combining elements like Hydrogen, Oxygen, and Nitrogen (H, O, N…) to form real molecules such as water and ammonia. Tackle 200 cleverly designed levels that challenge your brain without raising your blood pressure. Each level asks you to discover four target molecules by dragging through adjacent cells to select elements. Get it right, and you’re rewarded with a card describing what you’ve just created. New discoveries are added to your growing card collection. Molecule Maker is perfect for quick breaks, longer sessions, or that “just one more level” feeling. Relax, experiment, and enjoy a smart little puzzle game that’s as calming as it is curious.

Verdict
The clearest difference is ads: Molecule Maker at none against Quad Word's shown. Molecule Maker also leads on monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.8). Quad Word's advantage is ratings volume (13K vs 1) and iOS requirement (13.0 vs 17.6). On price, update cadence, in-app purchases and device support there is nothing between them.
