Normal sudoku rules apply.
In each cage there must exist a pair of orthogonally connected cells (a domino) that, when read left-right or top-bottom, give the total of all cells in that cage.
Digits must not repeat in cages.
Solution code: Row 5 followed by column 5 (18 digits)

Really cool puzzle! A couple of tricky steps, but most everything flowed superbly once you comprehend the consequences of the rule set!

Very cool. Did not think that ruleset could be enough to disambiguate everything, but it solved smoothly (with a little bit of arithmetic). Thanks!

Fantastic puzzle. Enjoyed it all the way from the start to end. Till I hit the solution code :) 18 digits, and I don't think it is working.
