Mega Mod Playground
About Mega Mod Playground
Mega Mod Playground is a free online sandbox game developed by JellyLab that lets you experiment with dozens of Geometry Dash-inspired characters, each with wildly different properties. Some characters float like they're filled with helium, others are dense and heavy, and many have unique abilities and health levels that react differently when they collide with hazards like spikes, poison, and balls scattered around the play area. There's no scoring or win condition here — the entire point is to click characters from the top panel, drop them into the sandbox, and see what chaos unfolds when they interact.
Mega Mod Playground runs entirely in your browser with no download or install required, and its simple point-and-click interface makes it accessible on both desktop and mobile. The appeal is purely in the experimentation: launching a helium-filled character into a spiky obstacle, watching a black hole swallow a rolling ball, or just filling the screen with as many wacky characters as it can hold to see what happens next.

Launching Crazy Characters
The playground panel at the top of the screen holds dozens of Geometry Dash-style characters, each with its own personality and physical quirks. Clicking a character automatically drops it into the game area, where it starts interacting with whatever else is already on screen. Blocks, spiky obstacles, poison pools, and bouncing balls all behave differently depending on which character touches them — a spiky item popping a helium-filled character, for instance, or poison slowly draining another one's health — so half the fun is discovering these combinations through trial and error.
Opening Black Holes
Beyond characters, Mega Mod Playground includes an orange portal gun that opens black holes anywhere on the map. Select it from the panel, drag it onto the play area, and click to open a swirling portal. Push balls or characters into the portal and they vanish entirely, sucked into the void — a satisfying way to clean up a crowded playground or engineer a dramatic finale to your latest experiment.
Tips for Experimenting in Mega Mod Playground
Start with just one or two characters at a time so you can clearly see how each interaction plays out before the screen gets too crowded. Pay attention to which characters are heavy versus helium-filled, since dropping a heavy character on top of a light one often triggers a different reaction than the reverse. Keep the portal gun handy to clear out characters that have finished their interaction, giving you a clean canvas for your next combination.
