World 6 · Event Horizon
Trailer
31 seconds of near misses.
How it plays
One gesture. Endless angles.
Every level is a single question: what launch makes gravity do the work? The rules fit in three steps. Mastering them takes 80 levels.
01 · Pull back
Drag to aim
Pull away from the probe like a slingshot. The dots show the first moment of flight, and not one moment more.
02 · Let go
Gravity takes over
Planets pull, moons swing past, black holes swallow, wormholes fold space. Your probe obeys real, deterministic physics.
03 · Dock
Thread the gate
Reach the gate to clear the level. Grab every fuel cell within par for three stars, then chase the developer's time.
8 worlds · 80 levels
From low orbit to core collapse.
Each world adds one new idea and gives you time to learn it before mixing it with everything else. Every level is checked by a solver, so every one of them has a three-star line.
Moon Belt
Orbiting moons, repulsors
Deep Field
Black holes, wormholes
Nebula
Solar wind, switch gates
Binary Stars
Thruster tap, pulsing wells
Event Horizon
Every mechanic, remixed
Asteroid Belt
Dense rock fields
Core Collapse
Black holes, everything at once
Daily Orbit
#—
One new level a day, the same for everyone. Dock in as few launches as you can, then share your card without spoiling the line.
Next orbit in --:--:--
Built for one more try
Short levels. Long nights.
Beat the developer
Every level has a dev time. Earn bronze, silver and gold medals, and the dev medal if you match it.
Gauntlet
An endless run of generated levels and three lives. How deep can you go before gravity wins?
So close
Missed the gate by 3 px? The game tells you, slows time near the gate, and keeps your best line on screen.
Fair, every time
The simulation is deterministic: the same launch always flies the same line. A solver verifies a three-star shot for every level.
Hangar
Unlock probe skins and trails with stars and achievements. 25 achievements to hunt down.
Music that reacts
An adaptive soundtrack rises as you aim, tightens near danger, and lands with the probe in the gate.
Questions
Slingwell in short.
What is Slingwell?
Slingwell is a free physics puzzle game you play in your web browser. You pull back to launch a small probe, and the gravity of planets, moons and black holes bends its path toward a gate. It has 80 handcrafted levels in 8 worlds, a new Daily Orbit level every day, and an endless Gauntlet mode.
Is Slingwell free?
Yes. Slingwell is free to play at slingwell.space/play, with no download and no account.
Can I play Slingwell on my phone?
Yes. It runs in any modern mobile or desktop browser and keeps working offline after your first visit. You can add it to your home screen to launch it like an app. Native iOS and Android versions are coming soon.
What is the Daily Orbit?
The Daily Orbit is one new level generated each day from the date, so every player in the world gets the same layout. You try to dock in as few launches as possible and can share a spoiler-free result card.
Is every level solvable?
Yes. The physics is deterministic, so the same launch always flies the same path, and an automatic solver has verified a three-star solution for every one of the 80 levels.
Who made Slingwell?
Slingwell is made by Badwi Finianos, an independent developer based in Paris, France.
