Otrio Board Game Rules: How to Play and Win

Quick answer

To play Otrio, set up the board, choose four pieces of your color, and take turns placing one piece. Win by getting three of your pieces in a row by size, in ascending or descending order, or in the same space as three concentric pieces.

How to play Otrio step by step

1. Set up the board and pieces: Place the board where all players can reach it. Give each player the four pieces of one color. If you are playing with fewer than four players, remove the unused colors so they do not clutter the board. Check that every player has exactly four pieces before the first turn.
2. Choose the first player: The rules do not name a starting player, so pick one at random or let the youngest player go first. Play then continues clockwise. Agree on the turn order out loud so no one argues after the first move.
3. Take turns placing one piece: On your turn, place one of your pieces on any empty space or on top of a smaller piece if stacking is allowed in your group’s interpretation. You cannot move a piece once it is placed. Before you place, check whether your move accidentally sets up an opponent’s winning line.
4. Watch for the three winning patterns: You win by getting three of your pieces in a row based on similar size, lined up in ascending or descending order, or within the same space as three concentric pieces. The first player to complete any one of these patterns wins. Say “Otrio” clearly when you complete a pattern so the win is confirmed before the next turn.
5. Block before you build: If an opponent has two pieces in a potential winning line, place your piece to block that line. Only start building your own line when no immediate threat exists. A block that also advances your own pattern is the strongest move.
