Understand the basics of Nim

Build familiarity through play

Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Refer to the controls when needed.

Aim for this result

Remove the last counter on the board to win. Keep that objective in view throughout the round. Try to explain the aim in your own words.

The order of play

  1. Player 1 chooses a pile.
  2. Remove at least one counter, and up to all counters, from that pile.
  3. The next player chooses a pile and an amount.
  4. Continue until no counters remain.

Controls

Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Check any mode label before starting.

Learn from a sample situation

With piles of 1 and 2, a move may empty one pile, but cannot remove one counter from both in the same turn. Apply the same reasoning to the position in your own round. Take a moment to compare.

Avoid this misunderstanding

Only one pile may be changed per turn. A different version of the game may use a different rule. After a move, check what changed. Decide which rule explains the new state before acting again.
