About Balance Board

A physics puzzle board game on a 7x7 white-wood board held on a single central point, where Indigo (you) and Vermilion (the CPU) take turns placing pieces. The weight of each piece really tilts the board, and once the tilt passes a piece's own angle it slides off and falls. After both sides place 16 pieces, whoever has more left on the board wins (an equal count is a draw). Drop 6 and you lose on the spot.

Tap a square and the tilt and the falling pieces appear as a preview before you commit, so you can take your time hunting for the square that drops only your opponent's pieces. The Daily Move, which changes at midnight, is the same board for everyone. It is a free board game with no sign-up, and it plays straight from a phone browser.

What is Balance Board?

Balance Board is a physics puzzle board game where you and the CPU take turns placing pieces on a 7x7 white-wood board held on a single central point. Like a scale, the board tilts slowly towards whichever side carries more weight. As the tilt grows, pieces start to slide and fall off the rim. A fallen piece counts against its owner, and whoever ends with more pieces left on the board wins.

Rules

Kinds of piece and their slip angles

PieceWeightSlip angleNotes
Wood (cube)116°The basic piece, always available. Indigo carries a branded bar, Vermilion a stamped ring.
Iron (cylinder)222°Tilts the board as much as two wood pieces, and holds its ground to the end.
Cork (disc)½10°Barely tilts the board, but starts to slide at the slightest tilt.

There are three piece mixes. Wood only uses wood pieces alone, mixed gives you two iron and two cork, and more cork gives you four cork pieces (the rest are wood). On iron and cork pieces, the small mark on the top face tells you whose they are by colour and shape (a ring with a bar for Indigo, a plain ring for Vermilion).

How a game goes

  1. Choose a mode and an opponent: on the title screen, choose Match (a game against the CPU) or Daily. In a match you also choose the CPU strength (Easy, Normal, Hard) and the piece mix (wood only, mixed, more cork).
  2. Tap a square to see the preview: tap one of the 7x7 squares and you see the peak tilt after placing, plus which pieces would fall. A dotted preview bubble appears in the spirit level.
  3. Tap again to place: tap the same square again, or press Place, to commit. The board tilts slowly, and once the tilt passes a piece's slip angle the piece slides off the board and into the box.
  4. Take turns until both have placed 16: Indigo (you) and Vermilion (the CPU) place one piece each in turn. The moment either side has dropped 6 pieces, that side loses.
  5. Whoever has more left on the board wins: the game ends once both sides have placed 16 pieces. Whoever has more pieces left on the board wins, and an equal count is a draw.

Reading the screen

Tips for winning

  1. Keep your own pieces near the centre: even as the board tilts, the nearer a piece is to the centre, the longer it takes to fall.
  2. When your opponent lines up along a rim, tilt that way: hunt for a square where the preview reads that vermilion will drop.
  3. Use iron two ways: as a counterweight to pull the tilt back, or as a weight to send it over in one go. It does not slide until 22 degrees, so it can go near a rim.
  4. The later the game, the more care: the more pieces on the board, the more a small imbalance tilts it. Once only the outer ring is empty, always check the preview before you commit.

The Daily Move (daily puzzle)

The Daily Move is a puzzle on the same board for everyone that changes at midnight. Pieces are already on the board, and you clear it by dropping the set number of vermilion pieces within three moves (indigo pieces may fall along with them). Clearing it records your streak, and you can share your move count and time on X. The shared text never contains the answer.

Practice (tutorial)

The first time you choose Match, a practice run starts that guides you through three moves on the real board (you can skip it). To see it again, start it from the button below.

Frequently asked questions

What kind of game is Balance Board?

It is a free physics puzzle board game where you and the CPU take turns placing pieces on a 7x7 white-wood board (a scale) held on a single central point. The weight of each piece really tilts the board, and pieces slide off if it tilts too far. Whoever keeps more pieces on the board wins.

What are the rules, and how do I win?

Indigo (you) and Vermilion (the CPU) place one piece each in turn until both have placed 16. A fallen piece counts against its owner, and the moment a side has dropped 6 pieces it loses. Once both sides have placed 16, whoever has more pieces left on the board wins, and an equal count is a draw.

When do pieces slide off?

When the tilt of the board passes that kind of piece's own slip angle. Cork starts to slide at 10 degrees, wood at 16 degrees and iron at 22 degrees. Pieces nearer the rim fall sooner. The spirit level at the bottom of the screen carries a mark for each of those angles.

What is the difference between iron and cork?

The iron piece (an iron cylinder) has a weight of 2, so one of them tilts the board as much as two wood pieces, and it holds on until 22 degrees. The cork piece (a cork disc) has a weight of one half and barely tilts the board, but it starts to slide at 10 degrees. Choosing the mixed set gives you two iron and two cork pieces; choosing more cork gives you four cork pieces.

Are there draws?

Yes. If both sides have the same number of pieces left on the board after placing all 16, the game is a draw. Careful play where nothing falls tends to end in a draw, so to win you use the preview to hunt for a move that drops only your opponent's pieces. Wins, losses and draws are all recorded.

What is the Daily Move?

It is a puzzle on the same board for everyone that changes at midnight. Pieces are already on the board, and you clear it by dropping the set number of vermilion pieces within three moves. Clearing it records your streak, and you can share your move count and time on X (the answer is never shared).

Any tips for winning?

The basics are to place your own pieces nearer the centre so they hold on even as the board tilts. Once your opponent's pieces line up along a rim, use the preview to hunt for a move that tilts the board that way. An iron piece can pull the tilt back or send it over in one go. The more pieces on the board, the more a small imbalance tilts it, so place with extra care late in the game.
