Best version of Futoshiki

This is by far the best version of Futoshiki on the app store. There are enough levels to present an excellent challenge and the presentation and mechanics of the game make for a very pleasurable gaming experience. Superb.

Nicely presented and simple!

After playing these puzzles in the daily newspaper it then found this app. The free version was quite generous, but after many years I returned to the app once again and purchased all the levels. Great value. Would have been nice if there was a deal to unlock all and also remove adds, but can’t grumble at a few quid for many hours of content.

Should I be able to find each number logically, or do I have to make intelligent guesses?

J’adore

Bien fait! Avec les petites notes que l’on peut placer.
Par contre, ça serait bien que les notes s’´efface lorsqu’on place un gros chiffre.
Merci pour cette application
