1B BalanceBalance puzzle for Android
Hang the pieces. Level every rod.
Brass rods hang from the ceiling of a museum at night. Hang the pieces from your tray on the right hooks — weight × distance has to match on both sides — and the whole mobile comes level. Then the spotlights come on, the sculpture turns slowly and it goes into your museum.
- An original puzzle
- Inspired by Calder's mobiles
- 56 sculptures in 8 rooms

One rod, explained
The whole game rests on a rule you already know from the seesaw. Here it is on a single rod.
- 1
Hang a piece
Hang a 3 two hooks to the left of the pivot: 3 × 2 = 6 on that side, and the rod tips over.
- 2
Weight × distance
A lighter 2 three hooks to the right also makes 6. Six against six: the rod comes level.
- 3
Every rod level
Do the same on every rod of the mobile — a rod also carries everything that hangs below it — and the sculpture is balanced.
The spirit level under each rod shows the heavier side; it clicks when the bubble sits between the marks.

Inside the game
One rule, a whole museum
Balance a sculpture, watch it join your museum, and walk through the rooms one new idea at a time.
01How a sculpture works
Every rod hangs from its pivot, and everything below a hook counts — single pieces and whole branches. Drag a piece over a hook and the sculpture tilts live, so you can feel the answer before you let go.
- A spirit level under every rod
- A counter shows how many rods are level
- Hints point to the next piece and hook
02Balanced: into the museum
When the last rod comes level, the spotlights come on, the sculpture turns slowly and it is framed on the wall next to its label.
- A poetic title for every work
- Three stars for the fewest possible moves
- A tubular bell for every rod that levels
03The Journey: eight rooms
The museum floor plan leads you through 8 rooms of 7 sculptures. Balance 4 in a room and the next one opens.
- Counterweight, Pinned, Lift and Mirror
- Vessels, Magnets, Scissors and Wind
- Every room has its own wall, floor and light
04Your museum
Every sculpture you balance hangs in your gallery, room by room. Open any work to see it turning again, or play it again.
- Works and perfect balances, counted
- Today's sculptures in a room of their own
- Play any sculpture again
Eight rooms, a new twist in each
Every room of the museum adds one idea, with its own little tutorial — and later mixes in an earlier one.
- Pinned pieces with a brass rivet that cannot be moved, and balloons that pull upwards like negative weight
- Mirror rods, where each coloured piece needs its twin at the same distance on the other side
- Vessels you fill or empty one step at a time, and magnetic pairs that take two neighbouring hooks
- Scissors that cut a thread and drop a branch that doesn't belong, and wind that pushes one end of a rod down

A quiet puzzle with a lot inside
Exactly one solution
Every sculpture is checked by a solver that proves it has a single solution — and sets the fewest moves for a perfect balance.
Today's sculpture
A new sculpture every day, with a streak that never punishes you for a day off.
The Atelier
Endless sculptures, generated one after another and each one checked by the solver.
Your own museum
Walk along your gallery walls and open any work to see it turning in its room, with its title, date and stars.
No pressure
No move limit, no timer, no game over. Undo as much as you like — even a Start over — and ask for a hint when you're stuck.
A museum at night
Calder-style metal plates, brass wire, a spotlight with dust in the beam and a window that follows the time of day.
Phones, tablets and foldables
Pinch or double-tap the wall to zoom in on big sculptures, even on the narrow outer screen of a foldable.
Made for everyone
Glyphs on coloured pieces for colour-blind players, reduce motion, optional sums and distances, and TalkBack on every hook.
Play your way
Controls
- Drag a piece from the tray onto a hook; a line of light snaps it to the nearest free hook
- Or tap a piece, then tap a hook
- Tap a magnetic pair to flip it; tap a vessel to fill or empty it step by step
- Pinch or double-tap the wall to zoom; one button shows the whole sculpture again
Accessibility and comfort
- TalkBack reads every hook — rod, side, distance and what hangs there — and offers Flip and Return to the tray
- Glyphs on coloured pieces, so mirror rods work without colour
- Optional sums and distances beside the spirit levels
- Reduce motion: calmer swinging and no spinning
- Unlimited undo, hints and no move limit

Questions and answers
What is a Calder mobile?
A hanging sculpture of rods and metal shapes that balance in the air, made famous by the artist Alexander Calder. 1B Balance turns that idea into a puzzle.
Do I need to be good at maths?
No. It's the seesaw rule: a light piece far out balances a heavy one close in. The spirit levels show which side is heavier, and if you like numbers you can switch on sums and distances in Settings.
Can every sculpture be solved?
Yes. Every sculpture is checked by a solver, which proves it has exactly one solution and sets the fewest moves for a perfect balance.
How can I play it?
1B Balance is available on Google Play: install it from its official listing. It needs Android 8.0 or later and no Internet connection.
