About Gravity Hole — Black Hole Runner (GamePix)
Gravity Hole on this page is a colourful lane-based black-hole runner supplied through GamePix. It is not a space simulator and it is not the planet-destruction game Solar Smash. The first playable screen shows a small dark hole marked with a size value, a track with people and objects ahead, red and green number gates, and upgrades labelled Size and Speed. You steer sideways while the run moves forward.
What happens in the browser version?
After the GamePix start gate and a Unity loading screen, the level opens with “Swipe to Move”. On desktop, click and drag horizontally across the game area to start and steer; on a touch screen, swipe. In our desktop test, moving the pointer started the run and the track advanced. Watch the displayed number on your hole and the values on the gates ahead. The green gates add to that value and red gates subtract from it, so choose your line before reaching a gate. Small objects and characters appear on the track, but this is a forward-moving obstacle course rather than a free-roaming field.
First-run tips
Use short side-to-side movements to line up with a favourable green gate. Do not assume an object is safe just because it is nearby: compare its size with your current value. The Size and Speed buttons show a cost of 100 at the opening screen, so they are upgrades for later rather than free controls at the start. We verified that the game reaches an interactive first level; we did not verify every later level or any purchase option.
Who provides the game?
The playable frame comes from GamePix and loads external Unity WebGL assets. Solar Smash hosts this guide and the embed, not the game files. If the frame stays on a loading screen, allow time for the assets to load and then retry the page or use GamePix directly. Loading can take longer than the first splash screen suggests.

Gravity Hole FAQ
Is this a realistic gravity simulator?
No. The embedded version is an arcade runner built around a black-hole character, numbered gates and upgrades.
What if the game does not start?
Activate the GamePix player and wait for the Unity assets. If it never reaches the track, reload once or try the provider page. An HTTP response alone does not prove the game has loaded.
Activate GamePix, wait for Unity to load, then click and drag sideways on desktop or swipe on touch. Steer toward favourable numbered gates and watch your hole value.
