Drop Planets: a free online merge puzzle about stacking a whole galaxy
Drop Planets takes the familiar drop-and-merge formula and sets it inside a shrinking galaxy: aim a falling planet, let it go, and watch two matching planets fuse into the next size up the moment they touch. Miss the timing and the pile creeps toward a danger line running across the top of the board — cross it and the run ends. The skill is less about speed and more about reading exactly where each drop will land before you commit.

How to play Drop Planets
Every round of Drop Planets comes down to the same choice: where to send the next planet. Matching planets fuse into a bigger one on contact, and each fusion buys you room before the pile reaches the danger line at the top of the board.
- 1
Line up the drop
Move the falling planet left or right along the rim before you commit to a spot.
- 2
Release it
Let go and watch it fall — a planet only merges when it lands touching a match.
- 3
Chase the fusions
Aim later drops near planets of the same size so contact turns two into one bigger planet.
- 4
Watch the danger line
Keep the stack low; once a planet settles above the line, the run ends.

Why players like Drop Planets
Physics you can read
Every planet falls at the same steady pace, so a miss comes from misjudging the drop, not bad luck.
A whole galaxy to build up
Matches climb from small rock to giant planet across many merge tiers, not just two or three sizes.
Fits a phone screen
The tall, portrait board is built for one-thumb play on a phone as much as a desktop tab.
Instant restarts
One key drops you straight back into a fresh run after a bad stack, no menu digging required.
Tips for Drop Planets
- Scan for the closest match first. Chasing a distant color across the board wastes a drop that could have merged instead.
- Leave a lane open near the middle. A single empty column gives you somewhere to redirect a bad drop.
- Don't rush every release. A slower, better-aimed drop beats a fast one that lands on the wrong side.
- Protect your biggest planets. Losing a large fused planet to a careless merge costs more progress than losing a small one.
- Use the pause key to think, not to stall forever. Planning the next few drops helps more than reacting on instinct alone.
Who is Drop Planets for?
Merge-game regulars
Already know the drop-and-fuse loop from other games and want a fresh, space-themed spin on it.
Players who like a visible failure line
Prefer a clear danger line over a vague game-over condition, so they always know how close a run is to ending.
Short-break puzzlers
Want a round that can end in two minutes or stretch to twenty, depending on how careful the drops are.
Scoring & winning
Merging two matching planets is what grows your total, and later, bigger fusions carry more weight than early small ones. Drop Planets has no fixed finish line — a run keeps going as long as the stack stays under the danger line at the top of the board. The moment a planet settles above that line, the run ends and your merged total becomes the score for that attempt.
