Mathdoku + Killer Sudoku + calculator!

MathDoku Extended integrates MathDoku and Killer Sudoku with calculator!

The game is based on the famous open source implementation of a well known sudoku-like games which uses a little math.

Our extension has several improvements over the original:

- on the same board you can play both Mathdoku and Killer Sudoku

- integrated call to our own DigitCalc - a simple calculator that computes all combinations of one-digit numbers which gives a desired result for selected mathematical operation. It is a standalone application which can be used with this and other sudoku-like games. If DigitCalc is called from the game, it automatically gives possible combination for selected cage considering already resolved cells and if cage is in line (so without duplicates).

- enabled long touch to fill cell. No need to constantly switch between normal and 'maybe' mode. Just tap shortly to put 'maybe' or long touch to put the solution into a cell.

- lazy mode option in settings to automate trivial solutions

- long press back button to set checkpoint and rewind to it

- long press cells with 2 or 3 'maybes' to remove trivial 'maybes' in other cells

- sum numbers in cages to help in Killer Sudoku solving

- bigger board

- bigger 'maybe' numbers

- 3x3 digit panel

- new theme with more visible colors
