Planet Merge Game

Planet Merge takes the drop-and-combine puzzle formula that made the "watermelon game" style popular and sends it into orbit. You launch small planets into an open play field one at a time, and whenever two matching planets touch, they fuse into the next size up — a moon becomes a small rocky world, that world becomes a gas giant, and so on. There's no timer forcing your hand, just a container that fills up if you stack carelessly.

Each shot is a small aiming decision: drop too randomly and the field clutters with mismatched sizes until you run out of room; line up merges deliberately and you can chain several combinations from one well-placed launch. The loop is simple to read at a glance but keeps demanding a bit more precision as bigger planets take up more space, which is what makes "just one more shot" easy to fall into.

Controls

Click and hold with the mouse to aim, then release to launch the planet. On a phone or tablet, touch and hold to aim, then lift your finger to launch.

Tips

• Keep one side of the field open as a landing zone rather than dropping planets straight down the middle every time — it gives you room to line up merges instead of stacking blind.
• Clear small planets early. Two tiny planets sitting unmerged take up space that gets more expensive to fix once bigger planets are in play.
• Watch the top of the container, not just where your next shot will land — a field that's fine now can overflow two or three merges later if you're not tracking the tallest stack.

It's a good fit for short breaks: rounds are self-paced, low-pressure, and easy to pick back up after a pause.
