TI-58/59 Make up your Mind Game
Back to main page Email me at: Gene!
This program first appeared in the V5N2P10 issue of TI PPC Notes (still available in limited quantities from former editor Palmer Hanson-email me for his snail mail address). Printer is optional. Master Library module is required.
Instructions: To play the game, the calculator produces a divisor between 2 and 10. The calculator then produces 15 numbers between 1 and 100 and displays each of them for about 1.5 seconds. You must decide if that number is divisible by the specified divisor. But, you must do so quickly. If you decide that the answer is YES, press R/S and if you are right, the number is added to your total points.

If you are wrong, the punishment is the subtraction of the number from your total accumulated points. If you let the number slip by and are wrong, only 1 point is subtracted from your total.

1) Enter a seed between 1 and 100000 and press A.
2) With a printer, the divisor is printed, otherwise displayed for about 3 seconds.
3) When the number is displayed, decide if its divisible by the divisor and press and hold down R/S if you think it is. If you stop the program, press E to continue.
4) With a printer, your current score will be printed, otherwise it will be shown in the display and the calculator will stop. Press R/S for the next number.
5) Once the 15 numbers have been shown, the calculator will print and display .11111111, followed by your total score.
6) Go to step 1 for a new game.
