How to play

How to Play Astro Merge

Move the drop position, release one planet into the container, combine identical planets, and shape the pile so later pieces can still land safely below the red line.

1. 01

   Read the current planet and both NEXT icons before dropping. Find an exposed identical planet or choose a low area where the current piece can wait without creating a tall peak.

2. 02

   Move the mouse or finger horizontally to aim according to the official controls. The in-game instruction also shows Left and Right Arrow input for moving the drop position.

3. 03

   Click, tap, or press Space to drop the current planet. Watch it fall and make contact with the floor or the existing pile.

4. 04

   Let the piece settle and check for an identical contact. Matching planets evolve into a larger stage and increase the score.

5. 05

   After a merge, inspect whether the new larger planet can reach another identical stage. Then update the plan using the newly advanced current and NEXT previews.

6. 06

   Keep the highest part of the pile away from the red line. Favor low merges, preserve open landing lanes, and avoid stacking several unmatched planets into one narrow tower.

About the game

Drop matching planets and keep the cosmic pile below the red line

Astro Merge is a gravity-based merging game played inside a tall container. Aim from the top, drop the current planet, and bring two identical planets into contact so they evolve into a larger one. Each merge increases the score and consolidates the pile, while every unmatched drop adds another round body to the limited space.

The in-game objective says to merge two identical planets, evolve them, reach the Sun, and never cross the red line. A visual progression strip at the top shows the stages as icons. Use those pictures to recognize matching pieces and likely results without assuming an astronomical name for every stage. The two NEXT icons let you plan beyond the current drop.

Because the pieces are round, a release point is only the start of the landing. Read the curved surface below and leave room for the planet to settle beside its intended partner.

A simple opening demonstrates the core rule: dropping two identical small gray planets into the bottom of the container makes them touch and combine into a larger brown planet. Watch the merged planet settle before choosing the next drop: its larger body changes the landing surface and may expose another matching planet.

Useful strategy

Plan the landing surface before you release the next planet

Shape a low pile with stable landing surfaces

Height is the main space constraint. A narrow tower reaches the red line quickly and leaves steep sides where a new planet may settle away from its intended partner. Spread early drops across the lower container when no immediate match is available. The goal is a low, readable surface with several exposed stages, not a perfectly flat arrangement.

Use the walls carefully. A side can contain a planet and make its first contact easier to judge, but repeatedly filling one edge can create a high column. Keep the center low enough to connect both halves of the pile. A large central planet can divide matching small stages and force future drops onto separate slopes.

After each landing, identify the new highest point and the broadest open lane. If the high point has an exposed partner, a merge there may reduce pressure. If it is made of unmatched planets, build on a lower region while waiting for a useful preview. Do not add height merely because the current piece fits on top.

Use two NEXT icons to plan a short sequence

Two previews support a three-piece decision: current drop, next drop, and the one after that. Begin by finding a destination for the current planet, then ask whether the resulting surface preserves an exposed match or safe waiting place for both upcoming icons. This is enough information for a practical sequence without guessing further random arrivals.

When consecutive icons match, reserve a shared low area where they can meet. The first copy may need to wait one turn, so place it on an exposed surface rather than under a larger body. When the previews differ, separate their destinations and avoid using one planet to close the only useful lane for the other.

Refresh the plan after every drop. A planet can settle against a neighbor, a merge can create a larger body, and nearby pieces can shift. The previews tell you what is coming, but the settled pile determines whether the old route remains available. Treat the sequence as a guide that must survive contact with the actual board.

Prepare chain merges from visible evolution stages

A chain is possible when the result of one identical pair can contact another planet at that new stage. Before releasing, compare the current pair with the evolution strip and locate the likely result's partner. If that partner is exposed on the same low surface, the first merge may continue without another drop.

Position matters more than merely owning the right icons. Two identical planets separated by a large body cannot merge until the pile changes. Likewise, creating a new stage on the opposite side from its partner may add height without delivering the intended chain. Build adjacent opportunities where the container shape and current surfaces allow them.

Do not force an uncertain chain near the red line. Take the first dependable merge and watch the result settle. If it reaches another matching stage, let the contact resolve; if it does not, preserve it as an exposed future target. The score display confirms progress, but this guide does not assume a fixed number of points for every stage.

Recover before the pile crosses the red line

The warning line is a signal to simplify. Stop building speculative setups and search the highest region for an immediate identical match. Consolidating two exposed planets replaces them with one evolved result and may reopen surrounding room. If no match exists, place the current planet in the lowest safe pocket that keeps its face reachable.

Avoid balancing a small planet on the highest narrow point. Even when it remains below the line at first, that placement can remove the broad landing surface needed by the next preview. Compare both upcoming icons and choose a side with space for their likely sizes. A recovery drop should create options, not postpone crowding for one move.

Once a merge lowers or reshapes the pile, rescan the entire container. The movement may bring another identical pair together, reopen the center, or expose a stage that was previously blocked. Recovery succeeds when several legal landing areas return. Chasing the Sun remains the long-term objective, but maintaining playable height comes first.
