Domino Castle Variations Contest

A Domino Castle Variations Contest was held on 15th January, 2011 from 16:30 - 18:30 GMT (22:00 - 00:00 IST).

The goal is to build correct Domino Castles in each puzzle. Domino Castle is an interconnected figure formed by complete domino set (from 1-1 to 5-5 for small puzzles, from 1-1 to 7-7 for big puzzles and from 1-1 to 4-4 for examples). Each domino of the set is used exactly once. Domino halves which share an edge should have the same digit.

Domino Castle is not one of my favourite puzzles, yet I gave it a shot, even though it being my birthday. I must admit, I enjoyed solving the set, though not very successfully :-)
I wonder why such wonderful contests have so few participants. Its just one of many question that every puzzler always seems to be having...

I didn't actually know about it at all. Granted, I haven't been very active in the last few months, but I would have maybe played had I known. Oh well.

Good job being the top Indian!

Haha! I wish there was at least one more Indian, then I could've boasted a bit :-)
