This is a simple Tic-Tac-Toe-like game. It has 8 x 10 field where you need to make a line of five in any direction - horizontal, vertical, diagonal - and so does your opponent. Whoever gets the line first - wins. Easy! Free version has ads. If you like them - great! If not - please buy us some coffee ($0.99) by getting Smart-Tac-Toe Premium. In the future, Premium will have all the new features, including unlimited field. Don't expect flashy graphics - the original game was (and is!) played on a blank piece of paper and we don't want to go too far from that. We think the game is good for people of any age - kids 5 and up (try to win yourself first), teenagers, adults. This is for you to enjoy!
