Rain Cup

Rain Cup is a lighthearted offline casual game built for Android phones in portrait mode. Slide your cup left and right to catch clean water drops, dodge dirty stones, and grab rare golden stars worth big bonus points. Every clean catch increases your score and combo streak, while mistakes cost lives and reset your rhythm. Rain grows faster and heavier every ten seconds with on-screen wave alerts, doubled spawn bursts, and rising challenge that stays fair and readable. The app includes five polished English pages: Home, Game, Rules, Stats, and Settings, with locally saved best scores, play history, difficulty presets, haptic feedback, sound state, and a reset option. Gameplay uses crisp Material icons, sky gradients, custom cup glow on successful catches, and touch controls that support drag and tap-to-move. Rain Cup requires no network access, no login, no ads, no third-party analytics, and no in-app purchases. It is packaged for Google Play with target API level 36, a unique application ID, and release signing ready for production upload.
