Conkers is a traditional children's game in Britain and Ireland played using the seeds of Horse Chestnut trees—the name 'conker' is also applied to the seed and to the tree itself. The game is played by two players, each with a conker threaded onto a piece of string: they take turns striking each other's conker until one breaks.
The conker eventually breaking the other's conker gains a point. This may be either the attacking conker or (more often) the defending one.
A new conker is a none-er meaning that it has conquered none yet.
If a none-er breaks another none-er then it becomes a one-er, if it was a one-er then it becomes a two-er etc. In some areas of Scotland, conker victories are counted using the terms bully-one, bully-two, etc. In some areas of the United States and Canada, conker victories are counted using the terms one-kinger, two-kinger, etc.
The winning conker assimilates the previous score of the losing conker, as well as gaining the score from that particular game. For example, if a two-er plays a three-er, the surviving conker will become a six-er (the sum of the two previous scores plus one for the current game).
