Android Giveaway of the Day - Combolit

A Combolit is a letter combination puzzle where each row contains the same number of letters of the solution. It is a pure logic puzzle like Sudoku that can be solved without knowing the language.
In variation "Combolit 2 of 5" there are exactly 2 letters of the solution present in each row, also called hits. These are all in the correct column (in the variation inverse, however, not a single hit is in the correct column).
There must be at least one hit in each column and each solution letter is present at least once.
If solution hints are enables, every letter you entered in the solution row will appear color coded in the list above:
- Red: Wrong position
- Orange: Wrong number
- Green: All conditions met

Above you can see an image with the correct solution LUCRE, where in each row the two correct letters are highlighted in green.
To the left is the same Combolit, but the solution is wrong. The rules are violated in four lines. The A's are red because these characters are not in the same column as in the bottom line. The rows containing orange marked letters have one or three hits, but you need two.

This puzzle generator app is the same as "Combolit Free", but it supports word lenghts from 4 to 10, while "Combolit Free" only contains word lists for the word length of 5.
Also included is the Sudoku mode, which can be tested with the app "Sudoku Combolit Free".
