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 600+ puzzles of different size grids for free, with even more coming soon! Puzzles range from easy 3×3 grids to tough 12x12s (best played on tablets).

A new hint system is now in the game to help you when you get stuck. Gain more hints by watching an advert, or buy some from the in-game store.

Due to overwhelming demand, the whole game is now supported by adverts – hide them with a single payment if you wish. Anyone who paid in the past will see no adverts and get a pack of free hints!

We’ve made lots of cosmetic improvements and intend to bring you more features as we continue to support the game into the future.

Thank you for supporting independent developers!
