Otrio, a game of strategy and observation
whose rule is very easy to understand
says Cathy Castin, at the toy library in Parthenay (79). The board looks like this:
With the rule of the traditional “noughts and crosses” which asks to align 3 circles of the same color, there there is also: the line of 3 elements of the same color and an increasing or decreasing line.
Otrio: from 2 to 4 players, from 8 years old.
