Gaming machine having plural gaming modes

A gaming machine, comprising:

• a symbol display unit for displaying/rearranging a plurality of reels including a plurality of symbols including a specific symbol;
• an input unit for inputting an instruction related to a game;
• a memory for storing a first symbol determination table causing the specific symbol to appear among the rearranged symbols on the symbol display unit with a first probability and a second symbol determination table causing the specific symbol to appear among the rearranged symbols on the symbol display unit with a second probability higher than the first probability and including a case that the specific symbol does not establish an awardable form after a rearrangement of the symbols, and a third symbol determination table bringing about a third probability of the specific symbol higher than the second probability and guaranteeing the awardable form after the rearrangement of the symbols;
• and
• a controller for starting the game in response to an instruction received through the input unit to execute the game in a first game mode and shifting the first game mode to a second game mode according to a game result in the first game mode,
• wherein the controller is programmed to execute processing of:
• (A) executing a game by the first game mode based on the first symbol determination table;
• (B) when a game result in the first game mode satisfies a predetermined condition, executing a game by the second game mode based on the second symbol determination table;
• (C) rearranging each of the plurality of reels in each of the games executed in the first and second game modes;
• (D) when at least one of the specific symbol appears in one of the awardable forms in a subsequent chance game mode executed in the processing (C), awarding a benefit and determining that a first termination condition is established to terminate the chance mode;
• and
• (E) when a game result reaches a final value, determining that a second termination condition is established and executing a final chance game mode based on the third symbol determination table to rearrange the symbols.

A gaming machine comprising:

• a symbol display unit for displaying a plurality of symbols including a specific symbol;
• a memory for storing plural kinds of data including data controlling appearance probability of the specific symbol, and a program for executing a game;
• and
• a controller for reading out the plural kinds of data from the memory, executing a normal game based on read-out data, and executing a continuation game depending on a result of the normal game with an appearance probability of the specific symbol higher than the normal game,
• wherein the controller temporarily increases the appearance probability of the specific symbol as a number of executed continuation games increases.
