Evolved Tic-Tac-Toe — 5 modes including Connect 4 and 3-player
Tic-Tac-Toe, but evolved. Dokopa packs 5 modes, and which ones you can play depends on the player count. For 2 players: "Super Tic-Tac-Toe" (nine 3×3 boards — Ultimate Tic-Tac-Toe), "Disappearing Tic-Tac-Toe" (your oldest piece vanishes once you have more than three), and "Connect 4" (drop pieces to line up four). For 3 players: "3-Player Tic-Tac-Toe" (5×5) and "3-Player Connect 4" (9×9). Play with 2–3 people on the free "Dokopa" app — in person or online by voice. Every mode is free with no stamina limits, so you can play as much as you like.
Decide who goes first (O) and second (X). In 3-player mode the order is O → X → ★.
Take turns placing one mark on an empty square, reading where your opponent is aiming.
The first to line up three marks vertically, horizontally, or diagonally wins. Block your opponent's threats early.
The first to line up three of their marks in a row — vertically, horizontally, or diagonally — wins. If the board fills up with no line, it's a draw.
Win conditions differ by mode, such as 3-Player (5×5 board) and Super Tic-Tac-Toe (81 squares).
In 3-player mode, the placement order is O, X, ★
