Blind Scale: Logic Puzzle, a cute balance-scale brain teaser for Android and iPhone

A few cute creatures look exactly the same size, but each one hides a different weight. You have one brass balance scale. Your job: put them in order, from lightest to heaviest, in as few weighings as you can.

A level in Blind Scale: two cute creatures on a brass balance scale; the text says Quobi is heavier than Zemmi, and the table below shows what is known so far.

A solved level: five creatures sorted on the table from lightest to heaviest, with three stars for beating par.

A twist level: Tuzo, the tired friend with a headband, on the scale against Quobi; the text says Quobi is heavier than Tuzo.

The basics

Weigh two. Tap a creature to put it on the scale, then tap a second one, or drag them onto the pans. The scale tips toward the heavier one, and the creatures react with funny faces.
The table remembers. Everything you learn is shown on the table below: lighter creatures sit to the left, and threads connect lighter to heavier. No notes, no memory tricks.
Pick the next pair. That's the whole game: one decision, over and over. If you already know which of two is heavier, weighing them again teaches you nothing.
Beat par. Par is the number of weighings a perfect player can always guarantee, however unlucky the weights are. Finish at par or under for three stars.
You can't get stuck. If a level runs long, simply try again with new weights. A hint shows a smart pair to weigh when you need a nudge.

Twists

Across 300 levels in 15 worlds, from Meadow to Starlit Marsh, new ideas keep it fresh:

Different goals: find only the heaviest, both ends, the top two, or the one in the middle.
Twins: two creatures that weigh exactly the same.
The sleepy friend: it has only a few naps left. You can poke it awake, but that costs two extra weighings.
The tired friend: after each weighing it has to rest for one turn.
The fibbing scale: it may lie once. Can you catch it?

Tips

Start by weighing creatures you know nothing about.
When you look for only the heaviest, a creature that lost once is out of the race.
Ask yourself: whichever way the scale tips, will I learn something new?
