Hollowline: Tunnel Ball Rush

Press anywhere and the ball starts rolling. Slide your finger to steer it through a glowing tube that bends, narrows and fills with obstacles. Let the ball hit a wall and the run is over.

Hollowline is built around one rule: every stretch of track you see has been checked before you see it, so every gap can be cleared with one finger. When you fall, it was the line you took, not the level.

WHAT IS INSIDE • 120 levels in a single Journey across 6 worlds, from Abyss Reef to Candy Reactor • Flow mode: an endless run for when you just want to keep going • A daily challenge on the same track for everyone • 18 ball cores to collect with the sparks you pick up along the way • Near-miss moments that reward cutting it close

CRASHED? ROLL ON A crash does not have to end the run. The big button on the card plays one short video and puts the ball back on the track right where it hit; if the video will not load, you get that revive anyway, once per run. Would rather start over? The small retry button is always there: a level's first retry is free, later ones play a video. No ad ever cuts into a run. Now and then a short one plays between runs, and a video can double the sparks a run earned.

EVERY LEVEL REMEMBERS YOUR BEST Each level keeps its three medals and the furthest point you have reached, so the card after a crash shows how close you came. Flow and the Daily keep their best distances, and your day streak and cores are kept with them in the game on this iPhone.

One finger. One ball. How far can you roll?
