LINEJUMP – One tap, one line, and no way to slow down

Tap. That's the whole control scheme.

No buttons, no swipes, no stick. One finger, three meanings, and a runner who never slows down for anyone.

Three things from one input

A quick tap gives you a hop. Holding the tap gives you the full arc, high enough to clear a wide gap. A second tap while you are already in the air slams you straight back down, which is how you cut a jump short when you have overcommitted. That is the entire scheme, and you have it inside ten seconds.

There is no brake

Your speed is not yours. It ramps up over the first stretch of a run and then holds, and nothing you do changes it. You cannot creep to the edge of a gap and look. You cannot wait for the thing in front of you to move. Every decision is made at running pace with the ground already disappearing, and that single restriction is what the whole game is built around.

The line is the world

One blue line across a dark screen, and you on top of it. It rises, drops, breaks open, coils into pipes and slides away underneath you. There is no scenery to read and no clutter to filter out, so the only thing your eye is ever doing is measuring the shape ahead.

Ten seconds to learn, and you will still be reading the line wrong an hour later.

Fifty-nine sections, and things that will not hold still

A route that reshuffles every run, enemies that change their own answer while you look at them, and a promise that none of it is ever impossible.

Built by hand, dealt at random

The track is made of 59 sections, each one designed on its own, shuffled into a new route every time you press play. Staircases fall away beneath you. Trampolines throw you at a ledge you cannot see yet. Platforms slide out from under your feet and a coiled pipe spits you out facing a gap. You will start recognising sections by their opening shape, which is the point.

The enemies ask a different question every time

Orbs hover above the line and none of them sit still. Some bob straight up and down, some slide side to side, some trace a circle, some run a figure of eight. When one is riding high you stay on the ground and pass underneath. When it dips toward the line you have to jump it. The obstacle is in the same place it was last time; the answer isn't.

Nothing is ever in a place you can't get past

Because you cannot slow down, an obstacle that is briefly impossible would be a coin flip rather than a mistake. So the game is built the other way round: every orb is small enough that there is no height at which it blocks both the duck and the jump, and every gap is checked against the actual jump arc at the slowest speed it can appear at. If you hit something, the timing was yours to get right.

Losing never feels arbitrary, which is the only reason a one-life run is bearable.

One heart, and a school for the bit that keeps killing you

Distance is the score, but how you cover it counts — and when a section beats you repeatedly, you can go and practise it on its own.

Leaps are graded on airtime

A jump is not just a jump. The longer you stay in the air, the higher the leap is graded, so committing to a full arc over a wide gap is worth more than a nervous hop over a narrow one. Stop within a whisker of the far edge and you take a PRECISE landing, which is the one thing in the game that rewards cutting it fine instead of playing safe.

School is a lesson for every single section

There is a mode with one lesson for each of the 59 sections, played on its own. When a particular staircase or a particular set of sliding platforms has ended four runs in a row, you go and run that section by itself until you have its shape, then take it back into a real run. It is the feature that turns a frustrating death into something you can actually do something about.

One life, unless you have another

You start a run with a single heart. Crash and it is over. Hearts are earned or bought and carried between runs up to thirteen, so a good stock turns a punishing evening into a long one — and running down to your last one changes how you play a gap. Race puts a ghost on the line beside you. Zen takes the pressure off entirely.

Missions rotate, a season fills with XP, chests open, and 160 cosmetics sit behind them.

The bottom line: one more run

LINEJUMP takes the one-tap runner and builds it around a single restriction — you cannot slow down — then makes sure that restriction is never used against you. Fifty-nine hand-built sections shuffle into a route you have not seen before, orbs circle and bob above the line to change the answer while you are looking at it, and every one of them is placed so that ducking or jumping will always get you through. Leaps are graded on how long you stay airborne, precise landings reward cutting it fine, and School lets you take any section away and practise it alone. There is one heart to start, more to earn, a ghost to race and a Zen mode when you want none of it. Every sound effect is generated inside the app and the four music tracks ship with it, so nothing streams while you play, and your progress lives on your phone with no account and no sign-in. It is free, it runs in English, German, Spanish, French, Indonesian and Portuguese, and the only advertising is a rewarded video sitting in the shop behind a button you press yourself.
