Description

Now, dive into chemistry! Alcyone is a brain puzzle designed for those with a scientific curiosity. It helps those who want to learn chemistry more easily and enjoyably, while offering a challenging and engaging experience for chemistry enthusiasts. Users worldwide have already recognized its highly effective learning experience. 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.

Build 883234087v1.4.02026-03-23 20:28:19

FUNCTIONAL GROUPS • Added a new type of Functional Group cell. • Functional groups can be acquired by spending credits after clearing Stage 3 (Lithium). (Starting with the Methyl group) • Subsequent stages allow sequential upgrades to other functional groups. • Functional groups work the same way as element cells in the grid; they do not react on their own but combine with other elements or molecules to create new molecular cells. • The list of obtainable functional groups starting from the Methyl group is as follows: Methyl, Ethyl, Propyl, Butyl, Pentyl, Hexyl, Heptyl, Octyl, Nonyl, Phenyl, Benzyl, Xylyl, Mesityl, Cinnamyl, Naphthyl, Vinyl, Allyl, Crotyl, Prenyl TEXT ANIMATION • Compound names are now displayed with text animations during formation and reactions. • Optimized the display methods and related code for existing text animations (combos, scores, special reactions). • Added a glowing shadow background effect to reacting cells that changes color (Blue/Red) according to temperature changes. • Chain reaction numbers are now displayed sequentially when multiple types of compounds react simultaneously. • Improved readability by adjusting the movement speed of temperature change text so it is not obscured by other text. • The stage clear result window now appears after the score animation is fully completed. SCORING CHANGES • Updated the scoring method based on the number of chain effects. • Changed the multiplier from linear (2x, 3x, 4x, 5x) to exponential (2x, 4x, 8x, 16x). • The score multiplier for simultaneous cell reactions was also updated to an exponential method (4x for 3 cells, 8x for 4 cells). IMPROVEMENTS AND FIXES • Added new fonts for Korean, Japanese, and Chinese. • Applied full-width indentation to the start of paragraphs in the Chinese encyclopedia. • Fixed punctuation (commas and periods) to be centered in Traditional Chinese. • Added sound effects for the Displace effect of noble gases (Helium, Neon, Argon, Krypton). • Fixed an issue where molecular structures were not displayed in aqueous solutions. • Corrected the molecular structure of formic anhydride. • Updated the molecular formula of boric acid to B(OH)3. • Removed background colors for metalloid element cells.

Build 882008754v1.3.62026-02-06 23:46:59

ADDING STAGE "REVERT" FEATURE • If you fail to clear a stage but have enough credits, you can use them to "Revert" the stage and try again. • The "Revert" cost is 200 credits at Stage 2 and increases by 40 credits for each subsequent stage. • However, if you continue a game that was in progress in a previous version, restore points will not be available, limiting the "Revert" feature and causing the game to reset. ADDING "UNDO" FEATURE • An "Undo" button has been added to the bottom left of the screen to recover from input errors. • The "Undo" feature cannot be used consecutively. OTHER FIXES • Fixed an issue where game information was displayed incorrectly on iPhone SE models. (Temporary measure: all info is accessible, but the UI is not finalized; it will be properly fixed when the layout design is overhauled) • Fixed an issue where volume and theme settings were not maintained after app restarts or recovery from sleep mode. • Fixed a visual bug where molecular structure animations were covered by bottom buttons. • Fixed an issue where phosphoric, phosphorous, and hypophosphorous acids were incorrectly set as strong acids. These compounds no longer trigger neutralization reactions. • Renamed alkylmagnesium halides to the more common term, "Grignard Reagent." • Corrected the Chinese terminology for Grignard reagent compounds. • Improved the readability of encyclopedia descriptions for sodium, magnesium, phosphorus, and sulfur compounds.
