A Good Sudoku alternative
for when you want a new kind of grid.
Good Sudoku is the sudoku app for people who want to get better at sudoku. Its makers wrote the puzzle generator and solver from scratch: the solver runs while you play, reads your answers and notes, and points you to the next technique you need, and every difficulty level is defined by the techniques it requires. Tare scratches the same itch — reasoning your way to the one correct answer — on a different board. Each of its 80 levels is a painted hanging mobile; you place numbered weights until every beam balances, and some weights hide behind a “?” that only picture-card clues can resolve.
How does Tare compare to Good Sudoku?
Two one-answer logic puzzles — a classic with a teacher built in, and a new rule on a hanging mobile. Here's where each one fits.
The puzzle
Tare: A hanging mobile. Drag weights numbered 1 to 9 onto hooks at notches 1 to 4 either side of each pivot until every beam balances — weight × distance equal on both sides, with a nested beam pulling its whole load at the hook it hangs from.
Good Sudoku: Classic sudoku, from a puzzle generator its makers wrote themselves. Custom mode lets you put in a puzzle from elsewhere — a paper puzzle you're stuck on, say — then play it and share it with friends.

The deduction
Tare: Some weights hide in a “?” bubble, and a beam carrying an unsolved “?” sways instead of tilting, so the scale won't tell you the value. Small picture cards — equal, heavier, balanced on unequal arms — let you deduce it.
Good Sudoku: Pure sudoku logic. Each difficulty is defined by the solving techniques it needs, up to advanced ones such as XYZ-Wings, Jellyfish and Swordfish, and you can practise each technique on its own.

Help when you're stuck

Good Sudoku: Its standout: AI-powered hints that run the solver as you play, work out what you already know from your answers and notes, and show you the next technique. Optional tools take over the counting busywork.

About Tare
Questions
FAQ
What is a good alternative to Good Sudoku?
If you want more sudoku, Good Sudoku+ is the Apple Arcade edition of the same game. If you want a different one-answer logic puzzle, Tare is a wordless balance puzzle for iPhone and iPad: you place weights numbered 1 to 9 on a hanging mobile until every beam balances, and deduce hidden weights from picture cards. Each of its 80 handcrafted levels is machine-checked to have exactly one answer. The first 20 levels are free, one $2.99 purchase unlocks the rest, and there are no ads.
How is Tare different from sudoku?
Sudoku asks you to place digits so each appears once per row, column and box. Tare asks you to hang numbered weights on hooks so that every beam on a mobile balances at the same time: weight times distance from the pivot must be equal on both sides, and a beam hanging from another beam pulls with everything below it. Some weights are hidden, and a beam carrying a hidden weight sways instead of tilting, so you deduce the value from picture cards. The logic feels familiar; the board is new.
Is Good Sudoku free?
Good Sudoku by Zach Gage is a free download with ads and a $4.99 Full Game Unlock in-app purchase. Good Sudoku+ is the Apple Arcade edition, included with an Arcade subscription. Tare is a free download whose first 20 levels are free forever; one $2.99 purchase unlocks the other 60, with Family Sharing, and there are no ads in either part.
Does every Tare level have exactly one solution?
Yes. Every level is built by hand and then checked by machine before it ships: it must have exactly one arrangement that balances, every hidden weight must be determined by its picture cards alone, and any decoy weight must fit no balanced arrangement at all. It's the promise a well-made sudoku gives — the answer can always be reasoned out, never guessed.
Do I need to be good at math to play Tare?
No more than sudoku needs you to be good at counting. The arithmetic is small — weights from 1 to 9 at notches 1 to 4, plus adding up the load that hangs below a nested beam. The challenge is the deduction, not the sums, and there is no timer.
Do Good Sudoku and Tare collect any data?
Tare's App Store label is Data Not Collected: no account, no ads, no analytics, no third-party SDKs and no networking code — its privacy policy has the detail. Good Sudoku's label is Data Not Linked to You and lists contact info, identifiers, usage data and diagnostics, including data used for third-party advertising; its release notes say it defaults to no tracking. Good Sudoku+ lists contact info linked to you, and identifiers and usage data not linked to you. Labels are self-reported and can change.
