Making your moves
- 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.
How to interact with the game

One way to understand the rules
With heaps of 1, 2 and 3 counters, choose one heap and remove at least one counter from it. You cannot take from two heaps in the same turn. Focus on why the action is allowed, not only its outcome. Look for the relevant detail.
Keep this in mind
Only one pile may be changed per turn. Compare the situation with the worked example. After a move, check what changed. Decide which rule explains the new state before acting again.
