Black Hole Gravity vs World Destroyer Simulator
Price, ratings, monetisation and update history for both games, side by side — with what reviewers say about each.
Black Hole Gravity
Read full descriptionHide full description
Black Hole Gravity is a quiet arcade about one instrument — light — and the one thing it can do here: bend around a black hole. You are the last keeper of the horizon. Drag to bend the beam: far from the hole it barely curves; close to the photon sphere it wraps around once, twice, three times before it leaves. Tap to fire a pulse along that path. Where it lands, matter moves. THREE ACTS I · THE WATCH — Worlds are sliding toward the horizon. Push them clear with light and hold the line for as long as you can. Every world you lose feeds the hole and makes it grow. II · THE NIGHT — The stars are out. Nothing to guard, nowhere to hurry. Bend the beam, watch it wind, and score by how far it turns. III · THE SOWING — The universe is cold. Push the last worlds into the singularity, shatter them into falling fragments, and grow the hole until it collapses into a new Big Bang. DEEP TIME One long run through five scales — from asteroids to whole galaxies — each around a real black hole: Cygnus X-1, Gaia BH3, Sagittarius A*, M87*, TON 618. Your enemy is Hawking evaporation. Five eras of the far future set the difficulty, and every singularity you reach births a daughter universe with slightly different laws. HONEST PHYSICS • The lensed sky and the Einstein ring are computed from the real mapping, not painted. • Winding the beam with the hole's spin draws on its rotation — superradiance (Zel'dovich 1971; Press & Teukolsky 1972). Each amplified shot slows the hole; accretion spins it back up. • Mass, Schwarzschild radius, Hawking temperature and evaporation time are shown live, computed from the hole you are playing. • Bodies that leave the screen are never teleported back: an escaping one is gone, a bound one returns on its own orbit — the edge marker tells you when. • Nothing changes under your finger. While you aim, the world waits. CONTROLS Adaptive aiming: the gear ratio next to the ship shows how fine your aim is — the closer to the capture boundary, the finer the control, so a three-winding shot is as steady as a straight one. A hardcore scheme with a log slider is there for those who want it. Two beacons, one under each thumb. A procedural soundtrack, four tracks, made from the same math. Sound designed for headphones: low pulses and singing bowls, nothing arcade. No ads. No tracking. No account. Works offline.

Pick a world. Pick a weapon. See what's left. World Destroyer is a sandbox where a planet floats in front of you and you take it apart. Tap to fire, drag to spin it, pinch to look closer. Each strike leaves a crater, the crust cracks and glows, the population ticks down, and eventually there is nothing left but a ring of rubble and a report of what you did. THIRTY-THREE WEAPONS Seven categories on the rail down the right edge. Meteors, storms, comets, an extinction-class asteroid and a moon dragged out of orbit. Lasers and a plasma lance you drag across the surface to carve molten scars. A black hole that stretches the world and swallows it. A supernova. A cleave that splits the planet in two along the line you tap. Saucers, a dreadnought, a strike wing and a drone swarm. A kraken, a world-eating worm, a void dragon and something ancient that opens its eye. Volcanoes, quakes, tsunamis, an ice age and a plague. And three ways to fight back: a shield, a guardian satellite and a terraformer that heals the crust. TEN WORLDS An Earth-like world of eight billion. A jungle super-earth. A red desert with domed colonies. An airless cratered moon. A banded gas giant with nothing to crater and everything to stir. A lava world already on fire. A frozen ocean with cities under the ice. A water world where the cities float. A ringed violet world. A volcanic-glass planet lit by neon cities. Every one is generated on your device, down to the coastlines, the clouds and the night-side lights. WATCH IT DIE Damage is not a number hidden somewhere. Craters have depth. Lava glows in the cracks and cools over time. The clouds darken, the atmosphere turns the colour of smoke, fissures race across the crust, and a world that has taken enough keeps losing people between strikes. Slow time down to watch a nuke go off, or speed it up to watch a plague spread. MADE ON YOUR PHONE There are no downloads and no assets. Every texture, every sky, every sound is synthesised when the app opens, which is why it is small and why it works with no connection at all. NOTHING ELSE No account, no sign-in, no ads, no purchases, nothing collected. Settings has a switch to reduce flashing for anyone sensitive to bright light.

Verdict
Black Hole Gravity and World Destroyer Simulator are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
