Begin with a lighter challenge

Easy often chooses among nearby points with more variety.

Practise reading threats

Medium looks for wins, blocks immediate threats and searches ahead.

Try a deeper reply

Hard uses a larger search budget on the same board.

Start your solo round

  1. Open the computer board. The main button restores your solo game and saved difficulty. A first visit uses Medium.
  2. Adjust the challenge. Press Vs computer to open Choose difficulty, then select Easy, Medium or Hard. Cancel leaves your choice unchanged.
  3. Place a black stone. You always begin. The computer replies with White.

The computer thinks between turns, and you cannot place its stones yourself.

Three levels, the same rules

Easy often selects a varied nearby move. It can overlook an immediate threat, giving you room to practise completing a line.

Medium checks for a winning move first, then blocks an immediate threat when one exists. It evaluates nearby continuations with a short search.

Hard uses the same tactical checks and a larger budget to look further ahead. It considers a limited set of promising moves, so it can still make mistakes.

These are casual practice opponents, not an unbeatable engine. Change the level through Vs computer at any time; your current board stays in place.

Practise one idea at a time

Start by looking for a line of three with room at both ends. Next, try making two threats that share one stone. The computer can place only one reply, so an attack in two directions can be difficult to stop.

Before extending your own line, scan White’s stones for a possible fifth. Look for gaps inside a line as well as at its ends. Review the gold-highlighted winning stones at the end of a round to see what decided it.

A full board of possibilities

You and the computer alternate placing one stone on an empty intersection of a 15 × 15 grid. An unbroken line of five or more wins horizontally, vertically or diagonally. A full board without a winner is a draw.

There are no captures or forbidden moves, and stones never move after placement. Black can start anywhere. Read the complete Gomoku rules for controls and examples.

Keep a practice game waiting

Your computer game saves separately from Same device mode in this browser. New round and Play again keep solo mode and the chosen difficulty, with Black starting again.
