Pulse Bounce

About Pulse Bounce

Pulse Bounce is about geometry rather than reflexes. Each shot reflects off the walls at equal angles, and the puzzle is working out which wall to aim at so the pulse arrives where you need it. The aiming guide shows only the first bounce deliberately — showing the full path would turn every level into a matter of lining up a drawn line, which is not a puzzle. Everything after the first reflection is yours to predict.

How to play well

The technique worth learning is the mirror trick. Instead of trying to visualise the bounce, imagine the target reflected across the wall you intend to hit, then aim straight at that imaginary target. The reflection angle takes care of itself. It sounds abstract and becomes automatic within a few shots, and it is the same reasoning that makes bank shots work in billiards. For two-bounce shots, mirror the target twice — across the second wall first, then across the first. Levels that look impossible usually have a two-bounce solution that a direct line cannot reach.

How it is built

Collisions are resolved analytically rather than by stepping the simulation until an overlap is detected. The code solves for the exact time the pulse intersects each wall segment, advances to the earliest of those times, reflects the velocity vector about the surface normal, and continues with the remaining time in the frame. This matters: a step-and-check approach lets fast-moving objects tunnel straight through thin walls between frames, which is the single most common bug in hand-written arcade physics. Solving for the intersection time makes tunnelling structurally impossible regardless of speed.

Nothing is collected

This game follows the same rule as every tool on the site. There is no account, no leaderboard server and no analytics event carrying anything about how you played. Your best score is kept by your own browser and never leaves the device — clearing site data for this domain erases it, and nobody else ever had a copy.

It also works offline once loaded, because there is nothing to load from anywhere after the first visit. That is a side effect of the same design: a game that never talks to a server has nothing to be disconnected from.
