Planet Merger vs Mobility Maker

Drop a planet. Watch it fall, collide, and merge into something bigger. Planet Merger is a physics puzzle about building the solar system one collision at a time. When two identical planets touch, they merge into the next one up — Pluto becomes Mercury, Mercury becomes the Moon, and on it goes. The board fills faster than you expect, the physics never quite behaves, and one well-placed drop can set off a chain reaction that clears half the screen. MERGE ALL THE WAY TO THE SUN Eleven worlds to discover, from tiny Pluto to the Sun itself. Every collision is driven by real physics, so no two games ever stack up the same way. Cross the line at the top and it's over — so think about where each one lands. LEARN SOMETHING REAL Every planet you unlock opens a card of genuine astronomy: diameter, distance from the Sun, number of moons, day length, year length, surface temperature. Plus the details that stick with you — like the fact that it rains diamonds on Neptune. 220 PLANET PUZZLES A separate quiz mode with 220 questions about the solar system, space exploration, and the science behind it all. Ten questions a round. ONE TAP TO PLAY Tap where you want the planet to fall. That's the entire control scheme. Easy to start in a spare minute, hard to stop when you're one merge away from a world you've never seen. PLAY IN YOUR LANGUAGE Fully translated into 9 languages, quiz questions included. Free to play. An optional one-time purchase removes ads permanently.

What happens when you put those parts together? Build a machine, set it moving, and find out. Mobility Maker is a 3D physics building and exploration game where your design shapes the adventure. Make a wheeled vehicle, a boat or a flying contraption, then test it in a world of hills, waterways and surprising routes. BUILD. TRY. REBUILD. Connect frames, wheels, engines and movement parts. Change their placement and balance to see how your machine behaves. A tumble into a ditch can be the beginning of a better idea. EXPLORE TO FIND MORE Look beyond the main path for hidden parts and fuel supplies. Discoveries expand what you can build. Return to a workshop, change your machine and tackle the next place with a different approach. Rebuilding preserves your remaining fuel. CHOOSE YOUR ADVENTURE Take on 12 courses, learn the controls in a separate practice course, or explore freely without a finish line. Follow a road, cross the water or take to the air with a design that suits the journey. KEEP YOUR BEST MOMENTS Challenge your personal best times. Record your journeys in the game and choose which videos to save or share. Recording and automatic saving have separate settings. Free to play with advertising and no in-app purchases. Rewarded ads offer fuel support; hidden functional parts are discovered through exploration. Ads require an internet connection.
