The present disclosure relates generally to systems and methods for providing game symbol removal operations in games. The game symbol removal operation allows a player of the gaming device to provide input regarding a set of game symbols to be removed from a first configuration of an array of cells. Removing the game symbol(s) in the set of game symbols from the first configuration of the array of cells forms a second configuration of the array of cells. A selected game symbol of the unremoved game symbols can have a higher probability of being a first game payline on the array of cells in the second configuration than on the array of cells in the first configuration. Removal of a particular game symbol from the array of cells allows a player to control his or her chances of winning and alter the proposed payouts for winning distributions of game symbols for at least one subsequent play of the game.

A guidewire-guiding device, and guidewire-guiding assembly. The device comprises a main guidewire channel and guidewire-guiding channels are respectively arranged in the guiding body. The main guidewire channel and the guidewire-guiding channels respectively pass through the guiding body along axial direction, and in-vivo end openings of the guidewire-guiding channels and the in-vivo end opening of the main guidewire channel are arranged along the axial direction at intervals. The guiding body may be imbedded into a vessel in-vivo via the main guidewire penetrating through the main guidewire channel, and as the in-vivo end openings of the guidewire-guiding channels are arranged along the axial direction at intervals, the to-be-guided guidewires enter the guidewire-guiding channels while being staggered to the main guidewire on the axial direction, therefore the problem of tanglement of the main guidewire the branch guidewires and other kinds of guidewires may be avoided.
