Does anyone know another name for this puzzle or a site or app where one can play it?
Edit: @Emrakul added some great information, in particular, the generally known name for it, which allows googling.
Now, the great thing about the version I linked above is that:
- it allows you to mark the edges which outline the dominoes individually, and
- it also keeps track of the number of adjacent instances of each number pair.
In other words, this is much better than the versions I have found given the name "Dominosa" because you can keep track of the incremental partial solutions and you don't waste all the time searching the puzzle grid manually.
Any additional leads on an app version with this support? (Or any volunteers :) )
