Ballast
Rate itFive crates weigh 1 to 5 kg: find which is which with as few weighings as you can.
on ballast.yukigames.workers.dev
Ballast is a daily deduction puzzle with a balance scale. Five identical-looking crates weigh 1, 2, 3, 4 and 5 kg, one each; you put crates on either pan, see which side sinks, and work out the full order from lightest to heaviest. Fewer weighings is a better score, with par at five.
About Ballast
Ballast gives you five crates and a balance scale. Each crate weighs a different whole number of kilograms from 1 to 5, and they all look the same. You can put any crates on the left pan and any others on the right, press Weigh, and the scale tips to the heavier side or balances. Every weighing goes into a history list, a counter shows how many orderings are still possible, and each crate's label shows which weights it could still be.
When you are sure, you arrange the crates lightest to heaviest and submit. Your score is the number of weighings; a wrong answer adds one as a penalty but tells you how many crates were in the right place. Par is five weighings for the daily puzzle. Solving it unlocks a six-crate hard puzzle with a par of six, and there is an archive of past days, unlimited practice and a short three-crate warm-up for first-timers.
The daily puzzle is the same for everyone on the same calendar day and changes at local midnight. The game is free in the browser, with no account and, at the time of writing, no ads. It is one of a set of small daily games by Yuki Andersen, along with Well Putt, Floe and Wellspring.
How to play Ballast
- Open Ballast; first-timers can try the 30-second warm-up.
- Tap crates to move them from the bench to the left pan, the right pan, or back.
- Press Weigh and note which side sinks or whether the scale balances.
- Repeat until the counter of possible orderings reaches one.
- Arrange the answer row from lightest to heaviest and press Submit.

Tips
- Weigh two crates against one: the result can split the possibilities into thirds rather than halves.
- If a pair loses to a single crate, the pair is almost certainly 1 and 2 or 1 and 3, and the single crate is heavy.
- Watch the possibilities counter to see which weighing tells you the most before you press Weigh.

Games like Ballast
Tipscale (Dayzle)
Also a puzzle of scales. Tipscale shows you balanced or tipped scales and asks for each shape's weight from 1…
Crack the Code (Puzzleship)
Each wrong guess at a lock narrows the code, much as each weighing narrows the crates.
Floe (Yuki Games)
From the same maker and numbered from the same first day. Three ice-sliding boards replace the scale.
Axiom (Mind Loft)
You spend a small budget of tests to find a hidden rule, so every test has to count.
Cardinal (Puzzleship)
Work out a hidden row of cards from clues about rank and position.
Wellspring (Yuki Games)
Another Yuki Games daily with a rank among the day's players and a share trail.
Einstein Riddles (Puzzleship)
Pure deduction again, six graded riddles a day instead of one scale.
