About

This game is entry into the SMSPower! coding competiton 2024. The game is a demo made from a WIP.

Everyone knows you can make words from alphabet Spaghetti. This game uses a related idea, where you have to make certain prime numbers out of Spaghetti numbers; where the prime numbers are all odd primes between 0 and 200. The purpose of the game is it is used for learning all the odd prime numbers between 0 and 200. In the game and on the left of the screen (see fig. 2) you will see a bowl with spaghetti numbers jostling about. The numbers there are read like characters of a book page- from top left to bottom right. So when the end of a line, at right of screen,is reached it continues to the left on the line immediately below it. So this means a prime number maybe on two lines of spaghetti numbers if it start near the end of some line. But the prime numbers will mostly be on one line in the average game.

Gameplay

Find as many primes in the displayed bowl of spaghetti numbers to beat the high score.

Game rules are:

the prime number to find must be odd and between 0 and 200.So this means the prime number 2 is not a valid answer.
for one digit or two digits primes they must exist with one leading zero or two leading zeros, in the bowl of spaghetti numbers to represent such primes. For example if 005 exists in the bowl then this is the valid (and only) answer for the prime number 5.
when all ten lives are lost or the time has run out then the game is over -entering an incorrect answer means a life is lost.
Primes are read from top left to bottom right (as mentioned in the about section). So for example this means if a prime number such as 199 appears only vertically, over three lines, then this is not a valid answer.
at least one point is awarded for every two correct prime numbers entered

So when playing your first few games, for pratice, it may help to have a printed out list of the odd primes between 0 and 200 and in later games just use only your memory without looking at the printed list.

Controls

Button 2 starts the game from the title screen.

In game controls are as follows.

Down key decreases the potential answer (displayed to the right of "ANSWER") to input.
Up key increases the potential answer (displayed to the right of "ANSWER") to input.
Button 2 enters you answer.
