Planet Plummet is a browser-based puzzle game built around controlled object placement and physics-based interaction. The player works with a sequence of falling planets that must be positioned inside a circular arena. Each session continues until space is exhausted and new objects can no longer be placed. The main goal is to merge matching planets efficiently in order to manage space and increase the score. The game emphasizes planning and spatial judgment rather than speed.

Gameplay Loop and Core Rules

The gameplay loop in Planet Plummet follows a consistent structure. A new planet is generated and prepared for release, while the player rotates the arena to select the best landing position. Once dropped, the planet interacts with others according to physics rules such as gravity and collision. When two identical planets touch, they combine into a single higher-tier planet, freeing space and altering the layout. The player must anticipate how future drops will interact with the existing structure to avoid blocking potential merges.

Rotation, Timing, and Placement

Control over rotation and drop timing is central to success. The arena can be rotated left or right to change how planets settle after landing. Drop strength may vary depending on how long the input is held, which affects bounce behavior and final position. Poorly timed drops can cause planets to stack inefficiently, increasing the risk of reaching the height limit. Precision and patience are required, as a single mistake can disrupt the entire structure.

Key mechanics that players manage during each session include:

•         Rotating the arena to guide planet movement
•         Controlling drop timing and force
•         Triggering merges between identical planets
•         Preventing the stack from reaching the upper boundary

These mechanics repeat continuously and define the strategic depth of the game.

Scoring Logic and Difficulty Growth

Scoring in Planet Plummet is directly tied to merge outcomes. Higher-tier planets grant more points, encouraging players to aim for long merge chains instead of quick fixes. As the arena fills, available space becomes limited, making positioning more difficult. Difficulty increases naturally through reduced margins for error rather than new rules. This creates a steady challenge curve that depends entirely on player decisions and planning ability.

Session Structure and Replay Value

Each session of Planet Plummet is independent and designed for repeat play. There are no permanent upgrades or progression systems that carry over between runs. Instead, improvement comes from better understanding of physics behavior and placement strategy. Sessions can be short or extended depending on player performance, making the game suitable for both quick breaks and longer attempts focused on high scores.
