Alcyone: Chemistry Puzzle is a deterministic, grid-based logic puzzle built around real chemical formulas and reactions. Players synthesize valid chemical compounds by aligning elemental tiles horizontally or vertically. As identical molecules trigger reactions, puzzles demand precise deductive reasoning across dynamic board mechanics: Synthesis & Match: Construct authentic chemical formulas across grid lines to trigger reactions and clear space. Phase Shifts: Ambient temperature controls state changes—gases rise, while liquids and solids settle with gravity. Reaction Cells: Specialized tiles catalyze distinct chemical pathways, including neutralization, hydrolysis, and organic synthesis. Free of timers and random elements, Alcyone delivers a pure, unhurried deductive experience designed for logic puzzle enthusiasts and STEM minds alike.
