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 colour 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.
