Planet Drop

Drop small worlds. Merge a universe.

A physics-based merge puzzle where every drop reshapes the board—and every roguelike upgrade changes the strategy.

01 — Drop

Core gameplay

Every drop changes the board.

Aim, release, and let physics take over. Space is limited, so one small decision can open a chain—or end the run.

01.1

Drop with intent

Position the next planet, anticipate its bounce, and make room before the container overflows.

01.2

Match and merge

When two identical planets meet, they combine into a larger world and create new scoring possibilities.

01.3

Build the chain

Read the board a few moves ahead and turn a difficult layout into a satisfying cascade of merges.

02 — Merge

Gameplay

Watch a universe take shape.

Simple input meets lively 2D physics. The rules are immediate; the board that emerges is different every time.

03 — Choose

Roguelike upgrades

Choose a rule. Change the run.

Upgrades alter size, score, gravity, and even planet behavior. Combining them turns a familiar merge puzzle into a new build each time.

↘

Smaller worlds

Shrink upcoming planets—or the entire board—to recover valuable space.

×2

Score multipliers

Reward careful planning with stronger score growth and powerful combinations.

⌁

Altered gravity

Change how the board settles and discover new ways to connect distant planets.

●

Special effects

Create rainbow planets and other effects that can rescue a run—or set up a spectacular chain.

How a run works

Keep merging before the board fills up.

Choose where to drop each planet. When two matching planets touch, they merge into a larger planet, increase the score, and change the space available on the board.

As the run progresses, choose upgrades that alter planet size, gravity, scoring, or special effects. The run ends when the planets cross the upper limit.

  • Aim the drop and anticipate the bounce
  • Merge matching planets and manage space
  • Choose upgrades to extend the run
