SUCUBE® is projected on a cube. Instead of the numbers 1 - 9 you have 1 - 16. Around a cube, there are 6 squares.
The rules are:
All six squares, all four rows, all four columns, all four rings contain the numbers 1- 16 only one time.
For a better overview, the cube is unfolded on the plain playing field.
The dark side of the cube, is shown twice at the top and to the right. This simplifies the control of rows and columns.
Modifications are copied to the corresponding square. Be careful: this two squares are twisted.
Selecting a free field the relevant fields are marked in green. A better overview of the rings is given by the green circles.
To write a number in the free field, mark a field and get the desired number from the upper right selection-square. If the selection was wrong, it is signalized with the bomb.
Try the Toggle "Reverse", the Hint-Button or Difficulty-Level and have fun.
You can play SUCUBE® on a Smartphone, if the display size is sufficient. The memory system might be to tiny.
