CCG Writes - "Tic-Tac-Letters is a fun puzzle game that shares a few similarities with Picross, but also adds an interesting Tic-Tac-Toe twist. The goal is to fill in all the boxes, and have the exact number of X's and O's for each column and row, while avoiding 3 in a row horizontally or vertically. On the harder levels, no two rows or columns should be the same. Each level has different letters to represent the X's and O's, but if that's too confusing there's an option called "Use XO". After beating each puzzle, a joke or pun is given."
