Addicted to brainy challenges just like us? Well, that's probably how you found our store! Otrio is an excellent 2-4 player head-to-head strategy game that will fire up your competitive side!

The rules of Otrio are simple; get three circular pieces of your color in a row in either ascending or descending order, the same sized pieces in a row, or three concentric pieces in the same space!

You can't find much simpler rules than this for strategy games which means gameplay becomes more deep and challenging depending on the wit of your opponent! Also, the wooden board sure is a beauty to behold and makes a winsome addition to your home decor.

Otrio is straight out of our Brain Workshop which means you can't find it anywhere else! If you're looking to show off your smarts in a brainy showdown, then look no further than Otrio.

Fun strategy game


We bought this for my son for a Christmas present. We all enjoy playing it! Age 8, 11, 14, 19 and adults. Great strategy game! We bought extras to give as gifts for upcoming birthdays!

Appealing to the eye!


Fun game for the kids! Not to mention great appeal!

Very Fun Game!!


My kids opened up this present today for Christmas. They started playing it and loved it immediately. It's similar to Tic-Tac-Toe only more challenging and interesting. They are aged 20, 18, 12, 10 and enjoyed playing it together considering their age differences. My husband and I liked it also. I would definitely recommend it.

shipped fast and in perfect order


I bought this as a gift and haven't opened or tried it yet. I will say my order shipped and arrived very quickly and in great shape with my order complete. No damage and fast.
