Description by Neil Rohan Written by the developer, not by AppBrain. Click to read.
Mystery Number Search is based on the "Hot and Cold" children's guessing game. One child is the clue giver and the other child is the searcher. The clue giver picks a mystery object in the room. As the searcher moves about the room, the clue giver gives clues, saying “you’re getting hotter” or “you’re getting colder” depending on whether the searcher moved toward or away from the mystery object. Once the object was found, the players changed rolls and the game continued.

Mystery Number Search uses NUMBERS instead of objects. The object of the game is to guess a randomly generated number, between 1 - 999, before your opponent can. You can play against another player on a WiFi network, or against a computer opponent if another player isn’t available. Clues are provided (just like in the Hot or Cold game) to help you narrow the guesses. An incorrect guess results in a colored Miss Circle being displayed, showing how far the guess was to the winning number. "Hint Arrows" are also provided.

SETUP Options

* Select the number of games needed to win the overall match. Range (1 - 10)
* Avatar selection (yours and your opponent)
* Computer Opponent skill level
* Sound On/Mute

GAME PLAY - SOLO MODE

Use the built in keyboard to enter a guess. When RETURN is pressed, the pointing hand points to the "CHECK GUESS" button.

Pressing "CHECK GUESS" causes the program to evaluate the guess. If there is no match, a Miss Distance Indicator is displayed.

Next (automatically), the computer opponent makes a guess. Its displayed along with a Miss Distance Indicator and Direction Arrow.

This process continues until a guess matches the Mystery Number. Once a player reaches the "Games To Win Match" mark, the match is over.

COMPUTER OPPONENT GUESSING

The computer opponent uses its previous guess and Range Indicator independently so as to continually reduce the range of its next random number guess.

** A match with an "average" opponent slightly favors you. The computer opponent makes purely random guesses within a smaller and smaller number range.

** A match with an "smart" opponent is a more even match; the computer opponent reduces its range by taking the low/high average.

** A match with an "peeking" opponent is a competitive match; the computer opponent reduces its range by taking the low/high average as before, but this time it peeks at your guesses and adjusts its low/high range limits.


GAME PLAY - WIFI MODE

Your opponent must have the Mystery Number Search app downloaded to a suitable device. This can be an Android or Apple device.

When opened, the program immediately sends you to the WiFi Setup page where you can verify YOUR avatar (or choose a new one), games in a match and sound option. Unlike the Solo Mode, there is only one avatar selection. The opponent will select an avatar on a similar Setup page.

Return to the Game Playfield. The avatars will automatically sync when both players have finished setting up their games.

To start the game, either player can press their green “Start” button. It becomes that player’s turn to go first. Play alternates between players after that.

The play is similar to SOLO MODE except your opponent will take a turn instead of the computer.

It should be noted that both devices can set the Games for Match value independently. This is a convenient way to give some advantage to a less experienced (younger) player and still make it interesting.



CHEAT MODE: Sometimes a parent might need to know the Mystery Number ahead of time in order to help direct a child. If the Cold (BLUE) indicator light on the light panel is pressed and held for more than two seconds, the winning number will be momentarily revealed.

Good Luck!
