Bolt Belt
Three lanes, three answers, and a crusher that only falls back while you stop making mistakes
About Bolt Belt
A steel ball rolls down a conveyor through a dark factory hall, and everything in the frame is either the machine or an answer. The machine is orange — gears turning at true belt speed, steel side beams, hazard trim. The answers are the only other saturated things on screen, and each colour means one input: red blocks are jumped, mint presses are ducked, magenta pillars are escaped by switching lanes. Yellow crates are the fourth thing, and the belt does not control those — they drop out of the dark onto the rubber, and you land on them to smash them.
Behind you is a crusher. It is not scenery. The gap between it and the ball starts at four and a bit metres and tops out at five and a fifth; running clean buys back about a third of a metre every second, and every clip costs one and three quarters. Three clips from a full gap is a kill. That is the whole tension of the game — the belt speeds up from six metres a second to ten over roughly the first four hundred metres, and the crusher is the thing that decides whether the mistakes you make at that speed are survivable.
What is different about this version
The runner usually punishes a mistake by ending the run. This one prices it. A clip takes one and three quarter metres off the crusher gap and resets your multiplier, and clean running pays the gap back at about a third of a metre a second — so a bad patch is recoverable if you stop making it worse, and a slow bleed of small errors kills you just as surely as one big one. You always know how close you are, because the thing that will kill you is on screen, six metres behind.
The framing is solved rather than chosen. The camera is set so that thirteen metres of belt are always visible ahead — about one and a third seconds at top speed — and row spacing is measured in seconds rather than metres, so the track does not become less readable as the belt speeds up. There is a guaranteed floor of seven tenths of a second between seeing an answer and having to give it, at any speed. Late input is forgiven twice over: there is eighty milliseconds of coyote time before touchdown, and a hundred and twenty milliseconds of buffering, so a swipe that arrives fractionally early still fires.
How to play Bolt Belt
- Read the colour, not the shape. Red means jump, mint means duck, magenta means change lane. The colours never swap meaning.
- A press that spans the whole belt has no lane to escape into — that one is always a duck.
- Yellow crates fall onto the belt ahead of you. Land on one to smash it; a hazard marker is painted on the rubber the moment the crate exists, so it arrives about a second and a half before the crate does.
- Collect the amber bolts. They do not affect the crusher, they are the second score.
- Clipping an obstacle does not end the run. It costs gap and breaks your combo. Running the crusher out of gap ends it.
- Distance is the score. Best is kept on this device.

Strategy
Treat the gap as a resource you spend, not a life bar you protect. Early on the belt is slow and the answers are cheap, which is when the gap should be pushed back to full — clean running is the only way to bank it, and there is no other time it is easy. By four hundred metres the belt is at top speed and you are making the same reads with a third less time.
Jumping is the expensive answer. An airborne ball is busy for six tenths of a second, which is the longest any single input takes you out of play, and you cannot change lane usefully while the arc is committed. When two answers arrive close together, plan the jump last if you can, and take the lane switch first — switching is the cheapest thing you can do and it repositions you for whatever is behind.
Near misses pay two metres each. Over a long run that is not nothing, but chasing them is how the combo dies; take them when the line you already wanted happens to pass close. And crates are worth going out of your way for early, when the belt is slow enough to make the landing comfortably — the same crate at ten metres a second is a much tighter ask.
Mistakes that cost you the game
- Reading the shape instead of the colour. At speed the silhouettes blur into each other; the three colours never do.
- Trying to lane-switch out of a full-width press. It spans the rubber — the only answer is a duck, and hunting for a gap costs the clip.
- Letting small clips accumulate because none of them ended the run. Three from a full gap is a kill, and the gap only refills while you are clean.
- Jumping first when a jump and a switch arrive together. Six tenths of a second in the air is the longest you are ever unable to answer.
Tips
- Push the gap back to full in the first two hundred metres. It is the only stretch where clean running is easy.
- Ride the middle lane when nothing is forcing you outward — both escapes are one swipe away instead of two.
- Watch the hazard marker on the belt, not the sky. The crate is only visible for the last half second of its fall; the marker arrives a second and a half earlier.
- Take the crates while the belt is slow. The landing window does not get wider later.
- A swipe can be chained inside one gesture. For a switch-then-duck pair you do not need to lift your thumb.
Questions about Bolt Belt
Does clipping an obstacle end the run?
No. It costs one and three quarter metres of crusher gap and resets your multiplier. The run ends when the crusher closes the gap entirely.
Can I get the gap back?
Yes — about a third of a metre per second, but only while you are running clean. It tops out a little over five metres.
Does the belt keep getting faster forever?
No. It climbs from six metres a second to ten and stops there, which a normal run reaches at around three hundred and eighty metres.
What are the bolts for?
They are the second score, shown beside the distance. They do not buy anything and they do not affect the crusher.
Does it cost anything?
No. Bolt Belt is free to play, runs in your browser, and needs no download, install or account.
