Kuiper

The merge game you know, flipped: you pull down to aim and everything you launch falls up. The pile grows toward you, and every habit from other merge games works against you. Matching bodies merge into a bigger one: two specks of dust make a pebble, two pebbles an asteroid, and on up to the star and the pulsar. You lose when the pile crosses the asteroid belt. CAMPAIGN 24 levels across six galaxies, each ending in a boss that breaks a different rule: one takes your Novas away, one buries the board in space junk, one hands it to you already almost full. The last one asks for something almost nobody gets: merge two pulsars and create a singularity. Every level keeps your best score and its world record, so there's a reason to come back long after you've cleared it. ENDLESS No levels, no ending. Just you, the slingshot and a world leaderboard that runs in seasons: on the 1st of every month everyone starts from zero, so showing up late doesn't lock you out. Your all-time best is kept separately and never resets. The longest run on record lasted 873 shots. FOUR SHIPS Earned with stars, by playing. Espectro shows you the next three bodies. Cazador holds one for when it suits you. And Devorador, which costs almost every star in the game, holds a body and fires a directed wave that pushes the pile away from the belt. WEAPONS The Nova — a laser in your ship's colour — disintegrates one body and shoves everything near it. The prism sweeps away every body of the same kind at once, wherever they are, and clears the whole board of junk. WHAT IT DOESN'T HAVE No ads. No purchases. Completely free — nothing interrupts your game and nothing is sold inside it. No sign-up, no email, no password. It doesn't ask for your contacts, your camera or your location. It plays fully offline — the internet is only needed for the leaderboards. Made by one person, in Spain.
