What's inside

  • A new board every day

    One daily challenge for everyone, with a streak that waits for you instead of punishing you.

    The progress screen: games won, best time, streak and no-hint wins
  • Hints that teach

    Stuck? A hint shows you where to look and why, so you learn the move rather than just getting the number.

    A hint, step 1 of 3: take a close look at row 3
  • Two players, one board

    Pass the phone or sit across the iPad and solve the same puzzle together.

    Two-player mode: two named players, each with a time, above a shared board

Small boards for small hands

4×4, 6×6 and 9×9 boards with animal pictures in place of numbers, their own profile, and stars and stickers for every finished puzzle. A wrong tile simply hops back, so there is no way to fail. The same app, so nobody needs a second download.

  • Own profile
  • Stickers, no scores

iPad + Apple Pencil

Write your notes in the square

Scribble a number and it is read as an entry; write small and it becomes a pencil mark. Landscape and portrait both.
