A tying article which is formed into one piece used for tying objects, where the tying article has at least two sets of all-in-one ratchet sets at its surface, which are distributed along two sides separated by boundary pieces and each side has at least one bar-like bodies, where the ratchet set of each bar-like bodies is made up of at least two ratchets. Pruning initiates rescoring in order to generate a new word graph with a revised best path. The voltage signals are then added up by an adder, and then the added voltage signal is attenuated by an attenuator, so as to obtain an RF signal having the same signal level as the voltage signal outputted from each IV converter. That is, the player keeps playing until the player’s skill produces the set number of successful outcomes.
