Ball of Line

Your trail is your weapon—and your weakness.

Drag and release to send your white ball across the arena. Cut through enemies’ red trails to defeat them. But watch out: enemies can hit the white trail you leave behind and end your run. Every launch is a balance between attacking and exposing yourself.

【FOUR WAYS TO PLAY】
• Survival: Defeat enemies, earn more time, and chase a new high score.
• Time Frenzy: Chain kills to earn extra seconds as time drains faster and faster.
• Boss Rush: Face a series of bosses, each with unique attack patterns.
• Hard Mode: Survive dangerous enemies and shifting penalties. No skill pickups or combo score bonuses, but your permanent upgrades still apply.

【ONE SHOT, MULTIPLE KILLS】
Use wall bounces and launch angles to take out several enemies in one shot. Knowing when to launch again can make all the difference.

【GROW AND CUSTOMIZE】
Earn experience and coins as you play. Unlock and upgrade skills, and collect ball appearances, trail styles, and hit effects to make every run your own.
