Diagonals – A Simple Two-Player Strategy Game
Play Diagonals, a simple two-player strategy game on a 3×3 board. Move your pieces, complete a diagonal, and block your opponent to win.
Game Intro
Diagonals is a simple two-player strategy game where players take turns moving their pieces across a small 3×3 board. The rules are easy to understand, but winning requires a little planning, careful positioning, and an eye on your opponent's next move.
Each player starts with three pieces and tries to arrange them along one of the board's two diagonals. The challenge is to get your pieces into the right positions while preventing your opponent from doing the same.
It's a nice little game to play with friends, siblings, or family members when you want a quick head-to-head challenge. There are no complicated rules or lengthy setup involved. Just open the game, take turns, and see who can outthink the other.
Diagonals currently supports local multiplayer only, so both players need to play on the same device. There is no online multiplayer at this stage.
How to Play Diagonals
The game is played on a square board divided into nine spaces, arranged in a 3×3 grid. Both players have three game pieces, and they take turns moving their pieces one step at a time.
The objective is to win by achieving either of the following conditions:
1. Complete a Diagonal
Move your three pieces into positions that occupy either of the two diagonals on the board. The first player to successfully occupy a complete diagonal wins the game.
Keep an eye on both diagonals while playing. Focusing only on your own pieces can leave an opening for your opponent to complete their winning arrangement.
2. Block Your Opponent
Winning isn't only about arranging your own pieces. You can also win by putting your opponent in a position where they have no legal move left.
This makes blocking an important part of the game. Sometimes the best move isn't the one that brings you closer to a diagonal, but the one that limits your opponent's options.
Game Rules
Here is a quick breakdown of the basic rules:
- The game board consists of 9 spaces arranged in a 3×3 grid.
- Each player gets 3 game pieces.
- Players take turns making their moves.
- Each move allows a player to move one piece one step at a time.
- Players must alternate turns.
- The first player to occupy either diagonal with all three pieces wins.
- A player also wins if their opponent has no available legal move.
The key is to balance your own positioning with keeping your opponent from getting into a winning position.
Game Controls
Diagonals keeps the controls simple, so you can focus on the game rather than figuring out complicated button combinations.

- Touchscreen: Tap the pieces and spaces to make your moves.
The game uses a straightforward click-and-touch control system, making it easy to play on both desktop and mobile devices.
Multiplayer Mode
Diagonals is designed for two players sharing the same device. You can challenge a friend, sibling, or anyone sitting next to you.

Final Thoughts
Diagonals is a small strategy game that keeps things straightforward. With just nine spaces and three pieces per player, every move matters. You need to think about where to place your pieces, watch for possible diagonal combinations, and avoid giving your opponent an easy win.
It's a good choice for a quick two-player match when you want something simple that still involves a bit of tactical thinking.
