Creates impossible puzzles
The game is faithful to the original Sumplete website, however, this implementation has a fatal flaw — it sometimes creates puzzles which are impossible to solve. I wish I could post the screen dump but will try to reproduce a real example below: 23. 9. 7 4 7 5 9 7 3 7 2 For the row, all numbers except “9” cannot be used. Eliminating the “4”, however, means the column cannot add-up to 23. This happens perhaps 15-20% of 5x5 games.
