PROBLEM TO BE SOLVED: To provide a game machine configured to determine a specific value to vary according to the state of variation and the position of symbols in symbol display means. SOLUTION: The slot machine 1 includes a main control board 100 for controlling the play, and a presentation control board 300 which has presentation lottery means 312 to extract a random number from second random number generating means 360 to execute a lottery for a presentation mode and which controls the presentation along the play. The second random number generating means 360 includes random number generating means (counter means 361, specific value storing means 362 and an updating means 365) having a prescribed number of bits and capable of generating a prescribed number of random numbers by adding a specific value to an optionally selected initial value, random number determining means 366 for monitoring random numbers, and specific value changing means 364 for changing the specific value. When the random number determining means 363 determines that a random number satisfies a prescribed condition, the specific value is changed by the specific value changing means 364.
