Modified from this page, to allow an arbitrary starting value of counters
- There is one pile of counters. The first player may remove any
positive number of counters, but not the whole pile.
- Thereafter, each player may remove at most twice the number of
counters his opponent took on the previous move.
- The player who removes the last counter wins.
- You move first: you can win from the initial position, but don't make any mistakes!
