City Hole
City Hole is an arcade game where you control a black hole in a city, swallowing everything in your path. Start small with fire hydrants and lamp posts, then grow large enough to consume buildings, trees, and even rival holes.
Key features

Guide
City Hole is a competitive arcade game where you control a black hole moving through a city, absorbing objects to grow larger. You start as a small hole that can swallow pedestrians, mailboxes, and small bushes. As you consume objects and grow, you become capable of absorbing cars, trees, buildings, and eventually entire skyscrapers. The game is a race against time and other holes to absorb the most mass before the round ends. Movement controls are straightforward. You steer your hole using the mouse, keyboard arrows, or touch input. The hole moves across a flat city map, and anything that fits inside the hole's diameter falls in. Objects too large for your current size block your path and cannot be absorbed until you grow. The size threshold is visual and intuitive: if the object looks like it would fit in the hole, it will fall in. If it looks too big, it will not. Growth strategy defines successful play. New players make the mistake of chasing large objects they cannot absorb yet. A more effective approach is to sweep through areas with many small objects first. Street sections lined with fences, hydrants, bushes, and lampposts provide rapid early growth. Once you are large enough for cars, parking lots become efficient feeding grounds. After absorbing cars, move to sections with buildings. This progression from small to large objects mirrors the natural growth curve and is faster than wandering randomly. Map knowledge gives a significant advantage. The city maps in City Hole have fixed layouts with objects placed in specific locations. Learning where clusters of small objects sit lets you plan an efficient route through the early game. Knowing where the densest parking lots are helps you transition into the mid-game. Knowing where the tallest buildings stand prepares you for the late game. Experienced players have a mental route they follow every round, optimized for maximum absorption speed. Competitive dynamics add a strategic layer. In multiplayer mode, other holes compete for the same objects. If another hole absorbs the objects in an area before you get there, that area is depleted and useless. Race to high-value areas before opponents. If a rival hole is smaller than yours, you can absorb them, which provides a massive growth boost and eliminates a competitor. If they are larger, stay away. Getting swallowed ends your momentum and benefits the opponent. The timer creates urgency. Standard rounds last two minutes. Everything you absorb within that window counts toward your score. After the timer expires, the round ends and scores are compared. This time pressure means you cannot afford to waste seconds on inefficient routes or hesitate near large objects you cannot absorb yet. Every second of movement should be spent absorbing something or traveling efficiently to the next absorption opportunity. Size classes define what you can absorb. At the smallest size, you can absorb people, small plants, and street furniture. At medium size, you add cars, small trees, and market stalls. At large size, houses, trucks, and large trees fall in. At maximum size, apartment buildings, skyscrapers, and other massive structures become targets. Understanding which size class you occupy helps you target the right objects. Attempting to absorb something above your size class wastes time because you slide around it without progress. The physics of absorption is satisfying. Objects tilt and tumble as they slide into the hole. Buildings crumble and fold. Cars bounce off the edges before falling in. Trees topple. The visual and audio feedback makes every absorption feel impactful. This sensory satisfaction is a major part of the game's appeal and what keeps players coming back. The dopamine response from watching a skyscraper collapse into your hole is surprisingly strong for such simple graphics. Hole versus hole combat follows simple rules. A larger hole absorbs a smaller hole on contact. The absorbed hole respawns at minimum size, losing all progress. The absorbing hole gains a size boost proportional to the size of the absorbed opponent. This risk/reward mechanic means approaching other holes is always a gamble. You think you are bigger, but are you sure? Misjudging relative size by even a small margin can cost you the round. Solo mode replaces competitive multiplayer with a score-attack format against the clock. The goal is to absorb as much of the city as possible before time runs out. Without competing holes, you can focus purely on route optimization and growth efficiency. Solo mode is useful for learning map layouts and practicing efficient absorption routes without the stress of competitors. The game demonstrates emergent gameplay from simple rules. The rules are: move, absorb things smaller than you, grow. From these three rules, complex strategies emerge: area control, opponent avoidance, route optimization, growth timing, and risk assessment for hole combat. No one programmed these strategies into the game. They arise naturally from players interacting with the system and each other. City map design affects gameplay significantly. Maps with evenly distributed objects favor steady, predictable growth. Maps with clustered objects favor players who know where the clusters are and can reach them first. Maps with lots of open space between object groups favor larger holes that can traverse empty areas quickly. Some maps favor aggressive early growth, while others reward patient players who avoid opponents and focus on safe areas. The scoring system in multiplayer mode typically ranks players by total mass absorbed. This means consistent absorption throughout the round matters more than a single large object at the end. A player who absorbs steadily for two minutes will usually outscore a player who spends ninety seconds growing slowly then absorbs one skyscraper. Volume of absorption over time is the metric to maximize. City Hole belongs to the .io game genre, named after the domain extension commonly used by these games. The .io genre is characterized by multiplayer browser games with simple mechanics, instant play, and competitive dynamics. Agar.io started the trend with cells absorbing each other. Slither.io adapted it to snake mechanics. City Hole adapted it to the black hole concept. Each game takes a simple consumption mechanic and adds spatial competition. Performance in City Hole depends more on efficiency than reflexes. The hole moves at a set speed that does not change with player input. You cannot dodge or move faster by clicking rapidly. What you can control is your path through the city. An efficient path touches every object cluster with minimal backtracking. An inefficient path crosses empty areas repeatedly and revisits depleted zones. The difference between a good and a great player is route efficiency. The game works as a short-session competitive experience. A full round takes two minutes. You can play one round and get a complete experience, or play ten rounds in twenty minutes. The quick round time makes it easy to fit into breaks, commute time, or any situation where you have a few spare minutes. There is no progression to lose between sessions. Each round is a fresh start. Visual scaling is well implemented. When your hole is small, the camera is zoomed in and you see individual objects clearly. As you grow, the camera zooms out to keep your hole and the surrounding area visible. At maximum size, you see large sections of the city from a high angle. This dynamic camera ensures the game feels appropriately scaled at every stage of growth. City Hole has educational value as a demonstration of scale and proportion. Young players develop an intuitive understanding of relative size as they learn which objects fit and which do not. The growth progression from small to large provides a concrete visual representation of accumulation and scale. These spatial concepts transfer to understanding size relationships in the real world. The browser version of City Hole requires no download, creates no account, and starts playing within seconds of loading the page. The simple controls work with mouse, keyboard, or touch. Performance is smooth on modern browsers, and the lightweight graphics ensure accessibility on lower-end devices. Round-based play means you can stop at any time without losing progress, since each round is self-contained.
