Heft: Balance Logic Puzzle

Every beam must hang level. Work out the hidden weights one step at a time across 360 puzzles of levers, mobiles, twin shapes and heavy beams.

Every beam must hang level. Can you find the missing weights?

Heft is a logic puzzle about balance. Brass beams hang from the ceiling, loaded with iron and copper weights. Some weights are hidden. Your job is to work out exactly how heavy each one is, using a single rule: weight × notches must match on both sides.

No guessing, no luck. Every puzzle has one answer, and every answer can be reached by pure deduction. Find the one weight you can solve right now, hang it, and watch that answer unlock the next step of the chain.

HOW IT PLAYS

• Tap an unknown weight to select it
• Build its value from the tray with 1, 2, 5 and 10 weights
• Hang it. A correct answer settles the beam level and lights its pivot green
• A wrong answer tips the beam toward the heavier side, so every guess teaches you something

FOUR CHAPTERS, FOUR RULES

• Levers: the classic balance. Weight × notches, left against right
• Mobiles: beams hang from beams. A hanging beam pulls with everything below it
• Twins: matching shapes weigh the same, different shapes never do
• Heavy Beams: every beam has its own weight, acting at its middle

Some puzzles also show the total weight of the whole mobile, giving you one more clue to work with.

360 PUZZLES Each chapter holds 90 puzzles that grow from a gentle warm-up into long deduction chains. The full Levers chapter is free, along with the first three puzzles of every other chapter.

HINTS WHEN YOU NEED THEM Stuck? A hint highlights the weight you can solve next and the beam to look at, without giving the answer away. You start with free hints and earn another for every 10 puzzles you solve.
