Mathdoku & Killer Sudoku

Integrates Mathdoku and Killer Sudoku with calculator!

This game is the descendant of "Mathdoku extended" which has the cleanest design and playfulness of all variants you can find. Now on the same platform you can play Killer Sudoku too. And that's not all.

We made this game for ourselves to play it daily. So we have introduced a lot of tools to skip trivial parts of the both games and have fun only with challenging parts.

Tons of new features are available:

- integrated DigitCalc, a simple calculator that computes all possible combinations of one-digit numbers in selected cage considering already resolved cells and whether duplicates are allowed.
- fill from DigitCalc option to start with 'maybes' only with possible digits
- lazy mode option in settings to automate trivial solutions
- infinite back moves
- set checkpoint by long tapping back button and rewind to it whenever you want
- long tap cells with 2 or 3 'maybes' to remove trivial 'maybes' in other cells in the same row/column/cage/segment
- option to sum numbers in cages to help in Killer Sudoku solving
- button to check progress
- new theme with more visible colours

You can play one game daily for free and others just by watching ad. Short intermediate ads could be avoided for a small amount of money, forever!
Development costs, sorry ;(
