Ludo
If the advance of a token ends on a square occupied by an opponent's token, the opponent token is returned to its owner's yard. The returned token can be re-entered into play only when the owner rolls a six. If a piece lands on the same space as another piece of the same colour, the pieces are doubled and form a "block". If the advance of a block ends on an opponent’s block, the latter is captured and returned to its owner’s yard, all together.
