G-Switch 4 — flip gravity, keep running. Free online
G-Switch 4 gives you a single button and a runner that never stops. Press it and gravity reverses, dropping you onto the ceiling; press again and you are back on the floor.
How to play
Your character runs automatically. Flipping gravity is the only input, so every obstacle is a question of when to switch surfaces rather than how to jump over it.

Tips & tactics
01Flip early. The character takes time to cross to the other surface.
02Gaps on both surfaces need a mid-air double flip — practise the timing on easy sections.
03The obstacle patterns repeat. Learn the sequence rather than reacting to each one.
04In multiplayer, the last runner standing wins, so surviving beats leading.
About G-Switch 4
The G-Switch series is one of the longest-running one-button platformers in browser gaming, and the fourth entry keeps the local multiplayer that made it a classroom favourite.
Everything happens on two surfaces, which makes it simple to learn and hard to master.
