About Trigger Runner

A side-on runner with exactly one input. You jump, and that is the whole vocabulary. The name comes from the spikes, which lie flush with the road until you get within a few car lengths and then punch up out of the tarmac, so the road ahead looks clear right up to the moment it is not. Pits open in the ground, missiles come in at two fixed heights, and after half a minute there are spiked blocks charging at you head-on.

You have three lives rather than one, and each hit gives you about a second and a half of blinking invulnerability, which is long enough to barge straight through the next hazard if you are quick about it. The score is simply how long you lasted, counted at sixty a second, so three thousand six hundred is a minute on your feet. Runs last one to three minutes and restart instantly, and your best is kept on the device. The appeal is narrow and honest: one button, a road that keeps speeding up, and the small satisfaction of finally reading a hazard you have died to twenty times.

What is different about this version

The hazards arrive on a timetable rather than at random. Missiles appear after twenty seconds, always announced by a warning and always in one of two lanes; charging spikes start at thirty-five. From fifteen seconds the run starts handing out effects, and there are only two: a permanent speed increase that can stack up to double your starting pace, and three seconds of low gravity. The spawner is deliberately kind in one specific way: it refuses to place a ground obstacle within about three quarters of a second of an incoming missile or charger, so impossible combinations never appear. Everything that kills you was avoidable. The gap between obstacles does tighten over the first minute, from roughly two seconds to a little over one.

How to play Trigger Runner

Press once to start running. You move forward on your own.
Press again to jump. That is the only control there is.
Clear spikes and pits, and read missiles by their lane before you commit.
Three lives, then the run ends. Your score is the distance you survived.

Strategy

The high missile is what ends most promising runs, because the instinct when something flies at you is to jump, and the high lane sits exactly at jump height. The low lane passes below you and the high lane passes above a runner standing still. Watch the warning, note which lane it marks, and be willing to do nothing at all. Doing nothing is a real move in this game and most people never use it.

The jump is more forgiving than it looks. A press is remembered for about an eighth of a second, so pressing slightly too early still fires the moment you touch ground, and there is a short grace window at the lip of a pit where a late press still counts as a proper jump rather than a fall. What does not exist is a second jump: once you are airborne your arc is settled, so the decision has to be made before you leave the ground. Late jumps clear single spikes comfortably; early jumps land you between a pair of them.

The two effects need different responses. Low gravity lowers your jump speed but halves the pull, which means you go higher, hang far longer and drift much further forward. Doubles become trivial and pit edges become treacherous, because you overshoot the far lip and land on whatever came next. A speed increase never wears off, so treat each one as a permanent change to the timing you have learned rather than a temporary nuisance.

Mistakes that cost you the game

Jumping at a high missile. It is at jump height; standing still lets it pass over you.
Tapping again in mid-air expecting a second jump. There is none, and the extra press does nothing.
Wasting the invulnerability after a hit. For a second and a half you can run straight through a spike, often the cleanest way out of a bad patch.

Tips

Jump late for single spikes, since they rise as you approach.
Treat the warning marker as the instruction: low means jump, high means hold still.
Under low gravity, jump earlier than feels right or you will sail past the far edge of a pit.
After a speed boost, expect every gap to arrive sooner than the last minute taught you.
If you are down to one life, take the safe jump rather than the tidy one.

Questions about Trigger Runner

Is there a shoot button?

No. Jumping is the only input, and nothing in the run can be destroyed.

Why do spikes appear from nowhere?

They are triggered. Each one stays flat until you come within range, then rises over a few frames.

What happens when I fall into a pit?

You lose a life and are dropped back in above the road, so the run continues if you have lives left.

Does the speed boost wear off?

No. It is permanent for the rest of that run and can stack until you are moving twice as fast as you started.

How is the score calculated?

One point for every frame you survive, at sixty a second. Distance, nothing else.

Is my best score saved?

Yes, in the browser on that device. Nothing is sent anywhere and there is no account to make.

Does it cost anything?

No. Trigger Runner is free to play, runs in your browser, and needs no download, install or account.
