The Nim playbook

Bring this focus to a round

Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Make the next step deliberately.

The purpose of your moves

Remove the last counter on the board to win. Keep that objective in view throughout the round. Return to the instructions when a step is unclear.

Follow these playing steps

  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.

Making selections and moves

Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Use the visible help when you are unsure of the next input.

One way to understand the rules

If only one counter remains in one heap, taking it wins under the normal-play rule used here. Use the example as a guide rather than a substitute for reading your board. Look for the relevant detail.

Notice this detail

Only one pile may be changed per turn. Take a moment to reassess the position before continuing. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
