1 direct deductions, 0 checks of forced consequences, 0 deeper searches and 9 open choices.
How this review works
Matching copies of a domino are interchangeable. Different placements or values count as different solutions.
Easy uses direct deductions. Medium includes one check of forced consequences. Hard requires several such checks or a deeper search. These are reasoning estimates; your experience may differ.
This hard board has 20 cells, 10 dominoes and 8 connected regions. Fill every cell and make all region conditions true at the same time.
Region A contains 3 cells; Region B contains 3 cells; Region C contains 2 cells; Region D contains 3 cells; Region E contains 4 cells; Region F contains 2 cells; Region G contains 2 cells; Region H contains 1 cell. Start with the smallest or most restricted region, then check how a domino’s second half affects its neighbor.
