Platformers typically treat gravity as an absolute law. You jump, you fall, you hit spikes, and you restart. Indie developer Robert Alvarez decided to throw that rulebook entirely out the window. In this browser-based puzzle platformer, the floor is only the floor until you decide the wall looks more comfortable. By completely removing the concept of a fixed "down," the game forces you to rewire your brain and approach spatial navigation from a four-dimensional perspective.
It sounds trippy because it is. If you are struggling to visualize your next move, constantly walking into spikes, or just trying to figure out how to beat all 24 space-bending levels, you are not alone. This guide breaks down the physics, the logic, and the momentum mechanics you need to conquer the shifting planes.

Breaking the Rules of Physics: The Core Loop
What makes this game uniquely addictive is its central mechanic: gravity flipping by walking off edges. In most platformers, walking off a ledge means falling to your doom. Here, walking off a ledge rotates your gravitational pull 90 degrees. Suddenly, the vertical wall you were just staring at becomes the ground beneath your feet.
This creates a deeply engaging, high-difficulty loop. You aren't just plotting a path from point A to point B; you are actively remapping the level's geometry in your head. The game falls squarely into the "Difficult Games" category because it demands aggressive spatial awareness. Every time you flip, obstacles like spikes change their orientation, meaning a safe route can instantly turn into a death trap if you don't calculate the rotation correctly.
How to Play Sides of Gravity
Mechanically, the game is stripped down to the bare essentials, ensuring nothing gets between you and the puzzle logic. The controls are tight, responsive, and cross-platform compatible.
Core Controls
Whether you are on a desktop looking for a browser game or playing the mobile version via touch, the inputs are straightforward. Here is the breakdown:
| Action | PC / Keyboard Input | Mobile Input |
|---|---|---|
| Movement | A / D or Left / Right Arrow Keys | On-screen directional buttons |
| Jump | W, Up Arrow Key, or Spacebar | On-screen jump button |
| Flip Gravity | Walk off a ledge (automatic) | Walk off a ledge (automatic) |
Gameplay Objectives
Your goal across the 24 space-bending levels is simple: reach the exit portal. To do this, you must manipulate your gravitational orientation to bypass gaps, scale impossible heights, and dodge lethal spiky obstacles. Progression is strictly linear, and the difficulty ramps up significantly around the mid-game as the level architecture becomes increasingly complex.
Advanced Strategy & Pro Tips
- Conserve Your Momentum During Shifts: This is the secret sauce to the game's physics. When you jump toward a wall and trigger a gravity flip, your momentum doesn't magically reset. You will carry that velocity into your new orientation. Use this to slingshot yourself across wide gaps by jumping just as the plane shifts.
- Visualize the 90-Degree Pivot: Before you step off a ledge, mentally rotate the entire screen. The spikes that are currently on the ceiling might become a floor trap once you flip. If you can't visualize the shift, trace the line from your character to the ground.
- Use Micro-Adjustments Post-Flip: Spatial disorientation is the biggest killer in this game. As soon as the camera shifts, take your hand off the movement keys for a split second to re-orient yourself. Holding the directional key during a flip often leads to accidentally walking right into a spike trap.
- Exploit Corner Jumps: Sometimes walking off the ledge isn't enough. You can jump off the very edge of a platform to clear an obstacle on the adjacent wall before the gravity takes hold, effectively cutting corners in 4D space.
Mastering the Hint System (Without Ruining the Puzzle)
One of the best features Robert Alvarez included is the built-in hint system, which is a lifesaver given the high skill ceiling. However, relying on a full Sides of Gravity walkthrough can ruin the satisfaction of solving the 4D puzzle yourself.
Instead of using the hint system to reveal the entire path, use it to confirm your first two moves. The hardest part of any level is usually the opening sequence—finding the "thread" to pull. Once the hint system shows you the initial gravity flip, pause the hint. Look at where your character is now standing and try to reverse-engineer the rest of the path to the exit. This keeps the game challenging while preventing pure frustration.
Compatibility & Technical Performance
As a modern web-based title, the game runs flawlessly across ecosystems. Whether you are looking for Sides of Gravity free online games on a desktop or playing via a mobile browser on BrowserGamers, the experience is identical.
The game requires no downloads and relies on lightweight HTML5/WebGL architecture. The frame rate is capped tightly, ensuring that the physics and momentum calculations remain perfectly consistent regardless of your device's hardware. The touch controls on mobile are surprisingly forgiving, though purists attempting zero-death runs will likely prefer the tactile feedback of a physical keyboard.
Is Sides of Gravity Safe for Kids?
Absolutely. From a parent's perspective, this is a phenomenal title for younger gamers, provided they have the patience for difficult puzzles. There is zero violence, no inappropriate language, and no multiplayer chat functions where kids could be exposed to toxicity. The game purely exercises logical reasoning, spatial awareness, and problem-solving skills. While the difficulty might cause some frustration for very young children, teenagers and tweens will find it highly engaging and beneficial for cognitive development.
Robert Alvarez has crafted a minimalist masterpiece that demands respect from its players. By twisting the fundamental laws of platforming, the game turns every wall, ceiling, and pit into a potential pathway. Master the momentum, trust your spatial logic, and those 24 levels will eventually bow to your shifting gravity.
Frequently Asked Questions
How many levels are in Sides of Gravity?
There are 24 uniquely designed, space-bending levels in the game, with the difficulty scaling up significantly as you progress.
Who created Sides of Gravity?
The game was developed by indie puzzle designer Robert Alvarez, known for creating intricate browser-based platformers.
Can I play Sides of Gravity on my phone?
Yes, the game features full cross-platform compatibility and can be played smoothly on mobile browsers using on-screen touch controls.
How do you flip gravity in the game?
You flip gravity simply by walking off the edge of a platform. Once you pass the edge, the game shifts your orientation so the adjacent wall becomes your new floor.
Is Sides of Gravity free to play?
Yes, it is completely free to play online with no downloads or installations required.
Does the game have a hint system?
Yes, there is a built-in hint system designed to help stuck players by showing them the correct path or initial gravity flips required to beat the level.
What happens to my jump momentum when gravity flips?
Your momentum is conserved during the shift. If you jump right before a gravity flip, that speed carries over into your new orientation, allowing for advanced maneuvers.
Are there enemies in the game?
No, there are no active enemies. The only threats are environmental hazards like spiky obstacles and the spatial disorientation of the puzzles themselves.
Can I play Sides of Gravity unblocked at school?
Because it is a browser-based HTML5 game hosted on platforms like BrowserGamers, it is often accessible on school or work networks, depending on the specific firewall rules.
Why do I keep hitting spikes after I flip?
This happens due to spatial disorientation. Try taking your hands off the movement keys exactly when the camera shifts to stop your character from walking forward into newly-oriented traps.
