How to play Nim
Nim gives you a focused activity to play in your browser. Remove the last counter on the board to win. Look at what changes after your first action. Check the rule that explains your first action. Check the relevant rule before repeating a move.
A useful comparison
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Keep the objective visible.
Your goal
Remove the last counter on the board to win. An attractive position is not enough unless the goal is met. Keep the controls in easy reach.
Step by step
- Player 1 chooses a pile.
- Remove at least one counter, and up to all counters, from that pile.
- The next player chooses a pile and an amount.
- 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. Return to the rules if the result is unexpected.
A useful example
If only one counter remains in one heap, taking it wins under the normal-play rule used here. Your next round may have a different position, so inspect it before acting. Notice the change in the playing area.
Watch out for this
Only one pile may be changed per turn. Take a moment to reassess the position before continuing. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
