The rules state that to chain jump, you must land on the next pad by exact count. This implementation does not consider over-jumping as an exact count. That is to say, if you jump past the edge of the board, and there happens to be a pad along that edge, you will not be permitted to continue jumping. This is a personal interpretation as I have been unable to reach the author. Please let me know if you are aware of any official ruling that goes against this reading of the rule.
