Cosmic Merge Drop at a glance

Guide updated

Cosmic Merge Drop is a free physics merge puzzle. You drop worlds into a tall jar, and when two identical worlds touch they merge into a bigger one, all the way up to a black hole. The round ends when the stack overflows the danger line, and everyone gets the same drop order each day.

How to play Cosmic Merge Drop

  1. Drag your pointer or finger to aim the next planet.
  2. Follow the dotted line and landing marker for a rough preview, then release to drop. With a keyboard, use the arrow keys to aim and Space or Enter to drop.
  3. Use the hold button to set aside one upcoming planet and swap it back once. Touch two identical objects together to merge them into the next size.
  4. Four merges charge Recycle. Use it to remove the highest small world and ease danger. Keep the stack below the red line for as long as you can; there is no time limit.

No account is needed. Your best score is stored only in your browser.

Controls and round details

Drag and release to drop, or use left/right arrows and Space or Enter. H uses Hold; R uses a charged Recycle. There is no time limit; a round ends only when the jar overloads. Calm Orbit changes to Rising Orbit after 12 drops and Cosmic Surge after 26 drops, and larger incoming worlds join the seeded sequence at the same points. The planet order is seeded by the date, so you can replay the same sequence and refine your placements.

Cosmic Merge Drop scoring

Matching worlds combine into the next, larger world. A merge scores more at each size. A merged world that merges again creates a chain multiplier up to four times, so keeping a path open for later pairs pays off. The danger line ends a round if settled objects crowd it for about two seconds. A charged Recycle removes the highest comet, moon or Earth on the board without awarding points.

The hold button first stores the next planet and reveals another. A second press swaps the stored planet into play; then hold is spent for that round. Save it for a drop that would block an important matching pair.

Cosmic Merge Drop strategy and tips

Build from one side. Keeping large worlds near a wall leaves a cleaner path for small drops and makes future combinations easier to predict.

Set up chain reactions. Place matching pairs close to the next-size object so one merge immediately creates another.

Respect the danger line. A rushed drop can wedge a small object above the stack. Watch the red overload meter: a settled object above the danger line for about two seconds ends the run. Recycle can clear a small object and reduce the meter; a safe merge can also open space.

Why the sequence changes daily

Every player receives the same seeded planet order for the calendar day. That makes scores more comparable while still giving you a fresh puzzle tomorrow. You can replay the current sequence to improve your plan and personal best.

Common Cosmic Merge Drop mistakes

  • Dropping in the middle every time. Build large worlds against one wall and keep a lane open for small drops.
  • Stacking small worlds on top of big ones. They wedge in place and push the stack toward the danger line.
  • Using Recycle too early. It removes a small world and lowers the overload meter, which matters most when the jar is nearly full.
  • Holding without a plan. Hold swaps back only once per round, so keep it for a drop that would block an important pair.

About Cosmic Merge Drop

Cosmic Merge Drop is a Tap Rush Arcade original in the drop-and-merge puzzle style, with a space theme: small comets and moons merge into bigger worlds, all the way up to a black hole. Real physics means worlds roll, bounce and settle, so no two drops land quite the same.

The daily drop order is seeded from the date, so everyone plays the same sequence each day and scores can be compared. There is no timer.

Cosmic Merge Drop: questions and answers

Can I use hold more than once?

You may store one planet and later swap it back once. The hold button is unavailable after the swap.

How does Recycle work?

Every four merges charge Recycle. It removes the highest small world (comet, moon or Earth) and lowers the overload meter. It is disabled if no small world remains. The charge is spent when you use it.

Is the landing marker exact?

It previews where a straight drop first meets the current stack. Physics can shift or bounce worlds after contact, so use it as a guide.

Does reaching the black hole end the round?

No. It is the highest merge goal; keep scoring until the jar overloads.

Is there a time limit?

No. The round ends only when the jar overloads.

Is the drop order the same for everyone?

Yes. The sequence is set by the calendar date, so every player gets the same order that day, and a new one arrives at midnight.
