Tri-ominos – Like Dominoes but a little more mathematical

July 14th, 2009 | Categories: games | Tags:

While tidying up the attic the other day I came across a very nice looking wooden set of tri-Dominos that someone had given me as a Christmas gift many years ago. I have no idea where it came from but it looks identical to the set below.


I enjoy playing traditional board games whenever I have the time and so my wife and I took a quick look at the instructions and played a couple of games.  It turned out to be good fun – much more interesting than traditional Dominos which we also play from time to time. The scoring involves a reasonable amount of simple arithmetic so if you have a child and want to get them to practise addition by stealth then it might be worth buying a set.

Amazon sell a Tri-ominos set (pictured below) that isn’t as nice as the wooden set I have but it’s quite cheap and probably worth buying if you’re curious. Let me know if you’ve played and enjoyed this game.


Finally, does anyone know of any computer implementations of tri-ominos in any format (Windows, Linux, Android, Windows Mobile, iPhone..whatever) – I couldn’t find one at the time of writing.

    Hi Sue

    I have no idea I’m afraid since it was given as a gift. If you click on the picture of the wooden set then you will be sent to a site that sells it but I’ve never used the site and so couldn’t vouch for it.

    Best Wishes,
