Able to solve using the techniques and strategies I have already developed using paper and pen. Easy to use and well graded. I especially like that, when you realise you have made a mistake, you can reverse all of your moves - which, of course, you can't do when using solving a paper/pen version. Edit: this app is not always fantastic reversing moves - sometimes it is sometimes it isn't - but still a good app and I am still addicted.

Like not being timed or number of errors counted. Not sure how to change level of play. But game works as expected and better than the others I have tried. Just keeping my mind active.
