Frequently asked questions
Is Tango the same as Binairo?
Very nearly. Tango is LinkedIn's version of Binairo/Takuzu with = and × links added. Hoot & Fox has both classic and Plus (linked) puzzles. We're not affiliated with LinkedIn.
Is there an unlimited mode?
Yes — Unlimited here in the browser, and Endless in the app.
Is the web Daily the same as the app's?
Yes, generated from the same date seed. Ranks, streaks and hearts are app-only.
Does the app work offline?
Fully. Only leaderboards and ads need a connection.
How much does it cost?
Free with ad breaks between puzzles. One optional £4.99 purchase removes them permanently and adds bonus hints, acorns and a board skin. No other purchases exist.
Can every puzzle really be solved without guessing?
Yes. Each one is checked by a solver that only uses the seven human techniques before it ships.
Is there an Android version?
Not at the moment. The browser version works on Android.
