Features:
- Normal grids completely free, with as many randomly generated puzzles as you like in many different levels of difficulty.
- With a single in-app purchase, you can unlock more complex puzzles with extra diagonals, gray squares and chaotic grids which require even deeper thinking combining all those intersecting regions.
- Sophisticated hint system which actually suggests possible ways forward using step by step logic. Especially in the beginning this is very helpful since even the easiest kaodoku grids can be daunting for those not used to them.
- Activate pencil notes in the settings so you can zoom in and freely draw whatever doodles you like, just like you would on paper.
- Alternatively, you can also use standard candidate marks to keep track of the possible symbols in each cell. In very difficult puzzles, the hints function will take these candidate marks into account if they are the only way of making progress.
- Share puzzles with others, export them in pdf or png format, or print them on paper to solve them the old-fashioned way. Feel free to publish puzzles in magazines or on websites, as long as you don't remove the kaodoku web address.
