55RTChain

55RTChain is a vertical color-pouring puzzle mobile game that combines observation, judgment, and precise operation. Players tap a transparent bottle containing multiple layers of colored ink, then tap a target bottle to pour. Only the same color can be stacked, while an empty bottle can accept any color layer. Successfully filling a bottle with a single color locks it and scores points. After all bottles are sorted, the game automatically advances to higher difficulty levels with more colors. Mistakes count toward a limit of three, ending the round if exceeded. Each step requires anticipating capacity and color order. The rhythm is relaxed and easy to understand, yet demands spatial planning and chain thinking, making it ideal for challenging higher scores in short sessions.
