Tic Tac Block • X O No

New way to play a classic game!

Tic-tac-toe just got a twist. Tic Tac Block is the classic X and O game — with one rule that changes everything: your opponent can block your move.

HOW IT WORKS Place your piece. Your opponent reviews it — they can Accept it and let it stand, or Deny it and force you to move somewhere else. But there's a catch: each player only gets one Deny per round. Use it wisely, because once it's gone, you have to Accept whatever comes next.

First to get 4 in a row — horizontal, vertical, or diagonal — wins.

FEATURES · 2 Player mode — pass and play with a friend · vs Computer — three difficulty levels to challenge any skill level · Easy — makes mistakes, plays casually · Hard — thinks ahead, plays smart · Evil — no mercy, no mistakes · Auto-Accept toggle for faster gameplay · Dark mode support · Simple, clean design that gets out of the way

THE STRATEGY Every move becomes a negotiation. Do you burn your Deny now, or save it for when it really matters? Do you play aggressively and risk getting blocked, or play it safe and let your opponent build their winning line? Tic Tac Block is easy to learn, hard to put down.
