Solutions are not unique I does Save small notes when using big marks and allows two colors of ink in small notes,
No Instructions :( It is hard to play with no instructions. Here is the best I could come up with on short notice: BOX at lower right lets you pick BIG (for sure your solution number) or HINT (where you can input multiple little number possibilities for that box). X will erase contents of a box. OK will wave your white flag of surrender and show you the full puzzle solution! Also, it seems that the vertical calibration is off, I need to point my finger or stylus at top of box just below to get it to read and enter correctly.
Don't bother You can't really play this game. No customization for difficulty. You can't put multiple possibilities into the boxes.
Not recomanded No instractions. Hard to control.
Horrible Game sucks
