Sometimes known as hidoku or hidato, you are given a grid with just a few numbers filled in. You must then build an ascending sequence of numbers going sideways or diagonally.
Play hundreds of puzzles of different size grids for free, with more on the way! Puzzles range from easy 3×3 grids to tough 12x12s (best played on tablets).
Use hints to help you when you get stuck. Gain more hints by watching an advert, or buy some from the in-game store. Find the free hidden hint each day!
The game is supported by adverts – hide them with a single payment if you wish.
We’ve made lots of cosmetic improvements and intend to bring you more features as we continue to support the game into the future.
