My friend also taught us how to play some game (I don’t know what it’s called) which is probably most related to Tic-Tac-Toe.
The only difference is you place your marker on the line intersections and you need to connect five in a row as opposed to three in a row. It was really fun! Jenny played him a couple times and then he gave us the game because he saw we liked it so much. He’s a great guy. :) Now, Jenny and I play it quite a bit.
