This is a casual game.
On an 8×8 grid, tap any plant to clear all orthogonally connected plants of the same type (minimum 2). Plants above fall down to fill gaps and new random plants spawn from the top. If newly placed plants form new connected groups, chain eliminations trigger with combo scoring. After chains settle, keep tapping to clear more groups. When no valid moves remain, "No moves left" is shown. Use Reset to start a new round (high score preserved) or Exit to return home for unlimited replay.
