How to Play

Each clue number equals the algebraic sum of its six adjacent tiles.

Win Condition

A board is only stable when every revealed clue and every flux ring requirement are satisfied together.

Control Rhythm

Read the legend first, then tap cells to cycle values. If a move needs to be cleared quickly, long press that tile.

Read the revealed clue tiles first, then place red and blue particles in the open operation cells.

Tap to cycle, long press to clear, and tap a clue tile to quickly review its six neighbors.

In later levels, also check fog, links, polarized flow, flux rings, and threshold clues.

Board Basics

Exact Clue

The bright outlined clue tile shows the target net charge for its six neighbors.

Operation Cell

The dark empty hex is an editable slot where you place particles.

Red +1

A red tile contributes +1 to nearby clues and flux-ring totals.

Blue -1

A blue tile contributes -1 and cancels or amplifies surrounding sums.

Hidden Clue

A dim ? tile is still under fog and must be revealed by stabilizing nearby clues.

Blocked Cell

The dark hex with an inner ring cannot be edited and only shapes the puzzle space.

Advanced Systems

Scan Fog

Solving the revealed clues expands the scan and uncovers more clue tiles nearby.

Quantum Link

Two cells with the same marker stay in inverse sync: one + forces the other to -.

Polarized Flow

Judge it from each clue tile. If the neighbor one step along the arrow is red, it counts as +2. If the neighbor one step opposite the arrow is blue, it counts as -2. The other four adjacent cells keep their normal values.

Echo Clue

The gold clue hides polarity and only reveals strength, such as ~2 for magnitude 2.

Threshold Clue

The cyan clue only sets a boundary like <2 or >0 instead of one exact value.

Flux Ring

Dot-marked cells with the same ring color belong to one flux region, and that region must hit its own net-charge target too.
