You control a small black hole dropped into a busy 3D city. Move into objects to absorb them, grow larger with every meal, and work your way up from street signs to cars, buildings, and eventually entire city blocks — including rival holes that get in your way.
Madness Hole was developed by MattonesCoolGames, built in WebGL/HTML5, and is free to play in browser on desktop, tablet, and mobile with no download. It’s part of the same “growing void” genre popularized by Hole.io (Voodoo, 2018), with a Madness Combat-inspired visual theme.

| Action | Input |

| Move the hole | WASD or Arrow Keys |
This is the entire control scheme, confirmed directly by the developer’s own itch.io page: “WASD – Move the hole around.” There’s no separate action button — absorption happens automatically on contact with any object your current size can consume. The only decision you’re making at any moment is direction.
How Growth Works
The game starts you as a tiny black hole in an environment “filled with objects of different sizes” — confirmed by dinosaur-game.io. Early targets are small: street signs, trees, debris, and small vehicles. As your hole absorbs these, it grows, and growth unlocks the ability to consume progressively larger categories: cars give way to buildings, buildings give way to city blocks, and at full size you’re consuming sections of the map itself.
Multiple sources confirm the growth curve accelerates — dinosaur-game.io specifically: “The more you eat, the faster your growth accelerates, turning quiet movement into aggressive expansion.” This means early-game decisions compound: time spent inefficiently early (missing nearby small objects, wandering toward distant large ones you can’t yet eat) costs more than the same inefficiency would later, because the growth rate at that point is at its slowest.
An object that’s too large for your current size simply cannot be absorbed — there’s no way to force it. The map’s object layout naturally creates a progression path: areas with dense small objects are where new holes spend their early game, while areas with large structures become accessible only once you’ve grown enough.
Opponents — Bots, Not Players
This is the detail most competitor pages either skip or get wrong. Y8’s description is explicit: “The main objective is to become the biggest black hole, competing against AI-controlled bots rather than real players.” Other sources describe “rival holes” and “competing players” in language that implies live multiplayer, but the only source that directly addresses this question confirms bots.
The developer’s own itch.io page supports this — it lists “Intelligent Bots” as a planned improvement area: “we intend to reprogram all the bots to make them better, fixing a lot of bugs and improving a lot the gameplay.” This confirms bots are a core, ongoing part of the game’s design rather than a placeholder. Larger rival holes — bot-controlled — can still consume you if you’re not careful, so the survival pressure is real even without live opponents.
Tips
▸ Stay in dense object clusters early, not toward big targets
The acceleration mechanic means early growth speed compounds. Routing through areas with many small objects packed together early gets you to the next size threshold faster than beelining toward a large object you can’t eat yet. The big targets will still be there once you’re actually large enough to consume them.
▸ Watch for bots that are visibly larger than you
Since opponents are AI-controlled bots rather than players, their behavior is more predictable but still dangerous — a bot that’s grown larger than you can consume you on contact just like an object would. If a bot’s hole looks bigger than yours, route around it rather than risk a close pass while you’re both moving.
▸ Don’t chase objects that are clearly out of reach
An object too large for your current size can’t be absorbed regardless of how long you sit on it. Recognizing the size threshold before committing movement toward an object avoids wasted time — if it’s not absorbing on contact within your current size class, move on to something you can actually consume.
▸ Check the skin selection before starting a match
The developer’s itch.io page confirms a skin selection menu. While purely cosmetic, choosing a skin before the match starts is the only customization step available — there’s no in-match cosmetic system, so this is a pre-match decision only.
