Two neutron stars merge into a black hole, which draws in the board.

The name is the endgame.

A kugelblitz is a black hole formed from concentrated energy rather than matter. Here it is what two neutron stars make when they touch, and it is the only thing that clears a full board.

It opens where the pair collapsed, draws everything into a spiral, and takes the board with it. Reaching one is both the highest score in the game and the way out of a pile that has stopped merging — the same move, at the same moment.

German for ball lightning.

A black hole at the centre of the arena drawing every body into a spiral — The board, on its way in.

Gravity pulls to the middle.

Drag around the arena to aim, then let go. There is no floor: bodies fall toward the center, and the pile grows outward. Matching bodies merge into the next one up.

Build the next body

Ten celestial bodies form the ladder. Only the first five drop; everything above a moon has to be built through merging.

Set off a chain

One merge can lead to another. Each link in the chain increases its value, up to eight times over.

Watch the ring

A settled body outside the ring for two continuous seconds ends the run. The ring brightens as the pile approaches and turns red when time is running out.

Ten rungs, and most runs never see the top.

Each body is made from two of the one before it. Only the first five ever drop; everything above a moon has to be built. Every rung you reach for the first time is named, and the ladder under your score fills in as you climb it.

A closer look

Heavy bodies work inward as the pile settles. Antimatter scatters the pile and can open a path to merges you could not reach with a drop.

Celestial bodies gathered inside the circular arena during a run — A run in progress.

A large antimatter blast scattering bodies in the arena — Antimatter makes room.

What decides a run

Heavy things sinkMass behaves like mass. A neutron star dropped onto a bed of dust works its way to the middle while the dust rides up over it, so the pile sorts itself as it settles.

Antimatter, for when it jamsTwo kinds of charge. The small one clears the dust and pebbles clogging the gaps and leaves everything from an asteroid up standing. The large one takes an asteroid with it. Either way the shove matters more than the crater.

Chains climb a scaleA chain is one drop’s consequences, and the notes rise as it runs, so a long cascade is a melody rather than a pile of blips.

Every merge answers backIn sound and in your hand, weighted by what you just built. A dust merge and a neutron star merge do not feel the same.
