Alcyone: Chemistry Puzzle

"Nothing is created, nothing is lost, everything is transformed." - Antoine Lavoisier, 'Elements of Chemistry'

A brain puzzle completed through the elegant laws of science.

'Alcyone' is a chemistry puzzle game set across the periodic table. Your goal is to weave scattered elements together to synthesize molecules, and assemble them to trigger chemical reactions. Molecules don't simply stay in place. As temperatures rise and fall, matter changes states between gas, liquid, and solid—floating up or sinking down. This unique system adds depth to the puzzle in a truly distinctive way. Design your own chain reactions and lose track of time in the world of chemistry. Simply enjoy the game, and real-world chemical knowledge will follow like a gift.

Build molecules and trigger reactions.

• Combine elements to synthesize a wide variety of molecules. Experience the vast world of chemistry and find joy in discovering over 1,300 real-world compounds.
• Compounds change through three phases—solid, liquid, and gas—depending on the ambient temperature. Their physical properties, where solids and liquids sink and gases rise, act as key variables in your puzzles.
• Place identical compounds in adjacent cells to trigger reactions. The more complex the elemental composition of the compound, the higher the score you earn, allowing you to find your own efficient scoring path.
• Your score increases exponentially as the number of reacting compounds grows and the chain reactions last longer. Strategize your placement to achieve the highest possible scores.
• From basic reactions like acid-base neutralization and hydrolysis to advanced organic chemistry, combine real-world chemical reactions to design and enjoy spectacular chain reactions.

Explore the periodic table and collect elements.

• Conquering numerous stages organized by atomic number, from Hydrogen (H, 1) to Krypton (Kr, 36), allows you to explore chemistry from basic to advanced levels step-by-step.
• Every time you complete a stage, you can collect new elements or unlock new chemical reactions that expand the possibilities of your experiments and your scientific toolkit.
• Upgrade each element to significantly boost your scoring efficiency. As you upgrade specific elements, the value of every compound containing them increases, letting you reach much higher scores.
• Acquire and upgrade organic functional groups to improve synthesis efficiency. Even compounds with complex structures can be created much more easily and quickly using upgraded functional groups.

Alcyone is continuously improved through regular updates. Focus entirely on the joy of chemistry without any in-app purchases or pop-up ads.
