Features

This game is version 2.7 of my fist game, Pick Num. In this game, the calculator will pick a random number and it is your job to guess it. Version 2.7 adds a better explanation and choosing of the difficultly level and is smaller in size.

Using

Digits

Pick the difficulty (or number of digits to play with). The more digits you play with, the greater the difficulty (each extra digit increases the difficulty 10 times). My favorite is "2" because games take about 5 turns.

Difficulty #	Numbers Are Between
1	1 and 10
2	1 and 100
3	1 and 1000
4	1 and 10000
X	1 and 10 to the Xth Power

Play

Try and guess the number the calculator has. The calculator will tell you if the number it is thinking of is higher or lower than your guess. You may guess as often as you want until you guess the number.

Strategy

How I Play

I start by guessing the number in the middle of the allowable range. For this example, assume I entered "2" as the difficulty, so the calculator is thinking of a number between 1 and 100. The number in the middle is 50. I try that and the calculator says "Try higher". Now I know that the number is somewhere between 51 and 100. The next number I try is 75 (right in the middle of the allowable range). In such, I am not merely guessing, but methodically narrowing down the possibilities, in order to find the number in the least number of guesses. It says "Try higher". All right, the number is between 76 and 100. Rather than try a weird number like 87, I try the next multiple of 10: 80. "Try lower". Now I know the number is 76, 77, 78, or 79. I try 77, which is somewhere in the middle. "Try higher". All right, it is 78 or 79. One in two chance. I just go with 78. "Try higher". Darn; it's 79.

Skipping

If you want to cheat and skip the problem, enter [Alpha][A] as the answer.

Scoring

For each round take your score from before and add the number of digits you play time 3 minus the number of guesses you make, plus the round number plus 1. This is your ongoing, cumulative score. After each round, the score which is displayed is your cumulative score divided by the number of rounds played.

Thus it is possible to see a decrease in your score if you take more guesses than 3 times the number of digits you are playing.

This scoring system was designed to be accurate for games of 2 or 3 digits.
