Merge Planets Deluxe

Drop tiny moons, merge identical worlds, and keep the board from overflowing as you chase the biggest planet possible.

The first time I played Merge Planets Deluxe, I thought it was just another drop-and-merge clone. Then a tiny Mercury landed on a Mars, and they fused into a Venus with a satisfying thunk. That's the loop: click to drop a planet, watch it settle, and hope you aimed well enough that two identical bodies touch. Merge two of the same tier and you get the next bigger world, from rocky moons all the way up to gas giants and beyond. The board is a simple container, but it fills up fast, and if anything crosses the top line, your run is over. What makes it stick is the physics. Planets aren't just glued to a grid—they bounce, roll, and slide depending on how they land. I've had a small moon ricochet off a pile and knock a Jupiter into perfect position, saving a run I thought was dead. You can see the next planet coming, so every drop is a tiny calculation: do I clear the low-tier clutter, or do I build a tower of same-sized planets near the wall for a later combo? The tension spikes when the board is 80% full and the only safe spot is a hair's width between a Saturn and a Neptune. Visually it's clean and readable: each planet has its own color and size, so you can scan the board in a second. The sound effects are subtle but satisfying—a soft pop when small worlds merge, a deeper rumble for the big ones. I kept coming back for that one more run feeling, especially after losing to a silly bounce that sent a planet flying the wrong way. It's simple to pick up, but the ceiling is higher than you'd expect.

Keep your biggest planets near the bottom center so smaller ones have room to land. Don't just drop randomly—plan two moves ahead because the next planet is shown. Merge low-tier planets quickly to clear space; they clutter the board fast. If a planet bounces off a high stack, try aiming for the opposite wall to slide it down. Save your highest-value planet for late game; merging it too early can backfire. Use the edges to funnel small planets into gaps between larger ones.
