Build

One legal construction

One legal three-piece constructionThree canonical five-cube pieces form one flat-side-connected construction. Piece one touches the green home territory.◆123TOUCH
your territory3 connected 5-cube pieces
  • Connect outward: at least one block is on or beside your territory.
  • Connect the build: all 3 form one group by flat sides—corners do not connect.
  • Stay in bounds: every block is aligned and fully inside the grid.
  • Do not rest on: black tiles or an opponent’s solid captured tiles.

CaptureThe enclosed center turns solid

Same footprint · center captured · worth 10

Cover = claim · 5Patterned and exposed. Opponents can cover it and take it.

Enclose = capture · 10Solid and protected. Opponents must bridge over it to take it.

How a claim captures: check all 8 neighbors—sides and corners. Each must be yours unless it is black or outside the grid.

What happens below?

Plain or patterned tile

Cover it → claim it. Enemy pattern flips to your color.

Dotted height tile

Claim only if the tallest block matches the dots exactly.

Black or enemy solid

Direct contact is illegal. A clear bridge can claim below.

Score swing

When you steal territory, you gain while its former owner loses.

Special tile

Match exact height

Use the tallest block directly above the dotted tile.

Too low or too high = no claim

Singlecaptured+10

Doublecaptured+20

Triplecaptured+30

Bonus unlock: match to claim; fully enclose to capture and score the bonus.
