Ball and Flag: draw the slope and guide the ball to the red flag
Ball and Flag turns each level into a small route-planning problem, and the path only works if your line has enough slope for the ball to roll. In this Sports game, you are not just steering around hazards — you are building the track itself, then watching whether the ball makes it to the red flag.
Draw a path that actually rolls
The key move is simple: sketch a line and make sure it angles downward, because a flat line will leave the ball stuck. That one rule changes every attempt, since you have to shape the route before the ball starts moving.
The movement also gives the game its puzzle feel, especially when you need to thread the ball between sharp obstacles without breaking the run. If you like drawing as a mechanic, this is all about turning a quick sketch into working physics.
Reach the red flag without hitting hazards
Each stage asks for one clear outcome: get the ball to the red flag and complete the level. The pressure comes from the dangerous spikes and other pointed obstacles in the city, which force you to think about where the rolling line should bend.
That makes it a neat mix of physics timing and route choice, where a small change in angle can send the ball safely forward or into trouble. The ball-and-obstacle setup also fits the obstacles theme naturally, because the level is really about reading space before you draw.
Similar rolling and drawing challenges
If you enjoy shaping movement by hand, you may also want a look at Draw Climber, which uses drawn movement in a different way, or Ball Gradient, another ball-focused challenge. For a more blocky puzzle structure, Bloxorz offers a different kind of board-based problem.
For a tougher obstacle course feel, Level Devil adds more trap-driven surprises to each attempt. Ball and Flag keeps its own identity by making the line itself the solution, and you can play it free on mobile and desktop.
