Sudoku
Excellent learning tool. Pick a style that allows clues and work thru a higher difficulty puzzle. When you get stuck,get a clue and if that is not enough, ask for more help. At any point in the puzzle, go to learning button to get a complete understanding.
There are so many difficulty levels, so you can choose a level that you can solve, then move up as you get better.
