City Ball takes you on a journey rolling through neighborhood alleys. Avoid obstacles such as trash cans, traffic barriers of varying heights, and traffic cones.

Beyond just dodging obstacles, you can collect red diamonds along the way to unlock different ball skins. With a three-heart health system and a temporary shrinking ability, every decision you make while rolling directly impacts how far you can go.
If you enjoy ball-control games that demand quick reflexes and precise obstacle dodging, give Vortex Ball a try to explore a challenging, twisting tunnel.
The ball rolls forward automatically along the neighborhood street, so you only need to focus on adjusting its position and handling obstacles. When you spot an obstruction, quickly shift to an open lane rather than waiting until the ball is too close. A well-timed lane change can help you avoid a collision and keep the journey going.
City Ball features a variety of obstacles, not just a single type. Trash cans, traffic cones, and differently shaped traffic barriers require you to observe carefully before deciding how to get past them.
For obstacles that can be sidestepped, quickly move the ball to an open lane on the left or right. However, some barriers span the entire width of the path, requiring you to use the ball's special ability instead of simply changing lanes.
This mix of obstacles ensures the journey never becomes a repetitive, monotonous task. You must identify the obstacle ahead and choose the appropriate way to handle it.
To guide the ball safely through the course, you need to watch for obstacles ahead and flexibly switch between the three lanes on the path.
The ball moves only between three fixed positions on the track: left, center, and right. Since you cannot steer the ball freely in all directions, every position change must be calculated based on the obstacles appearing ahead.
If an obstacle is in the center, you can shift left or right. However, if obstacles also appear in the adjacent lanes, rapid direction changes could leave you in a difficult situation.
The ability to shrink is a special mechanic that sets City Ball apart from standard ball-rolling games. When encountering barriers that cannot be easily bypassed by changing lanes, press the down arrow key to instantly shrink the ball.
This effect lasts only about 3 seconds, so timing is crucial. Shrinking too early might cause the effect to wear off before the ball fully clears the barrier. Conversely, waiting too long could result in a collision before the ball has time to shrink.
Observe the distance to the barrier and initiate the shrink at the right moment to ensure the entire passage under or through the barrier falls within the effect's duration.
The controls consist of the following three basic keys:
| Key | Function |
|---|---|
| Left Arrow | Move the ball to the left position |
| Right Arrow | Move the ball to the right position |
| Down Arrow | Shrink the ball for about 3 seconds |
