Arcspire
Storm grid puzzle

Drop it.
Fuse it.

The circuit

Four beats to every drop

Arcspire is played one tap at a time on a five-column grid. The thinking happens between taps.

1

Drop

Tap a column and the charge in hand falls to the lowest free socket. The next charge is always on show.

2

Fuse

It swallows every touching charge of the same value and climbs one level per charge: three 8s make a 32.

3

Chain

Fused charges fall and meet new neighbours. Each link of a chain scores more than the last.

4

Overcharge

Four links from one drop Overcharge the grid. Forge a 64 or higher and a beacon lights.

FIRST 40 DROPSClear air

Room to plan and build long chains.

FROM DROP 40Gale

Insulator blocks start rising from the bottom row.

FROM DROP 120Tempest

Insulators rise twice as often and false flashes blind the sky.

Three ways up

Pick your storm

ENDLESS

Endless Grid

Fuse until no column can take another charge, then relight the grid once with Joules.

60 SECONDS

Storm Rush

A sixty-second sprint where every fusion buys back a second.

ONCE A DAY

Daily Grid

The same order of charges for everyone that day, a daily reward and a streak with chests on day three and seven.

Between climbs

The workshop

Every new charge from 16 upward answers a Tesla Coil, which joins your collection with a Joule bounty. Joules earned on the grid pay for everything in the Bazaar.
