A new prototype

We need to improve on our prototype so that it conveys the concept of the game better.

This is my idea thus far:

Whoever is playing must hide their eyes or step out of the room while someone else hides various items around the area. The items can be just about anything, but there should be some groups of items that are the same. For example a few poker chips, a few pencils, a few golf balls, or anything else of the sort. The items will have an assigned value. In this case poker chips will be worth 25, pencils will be worth 50, and golf balls will be worth 100. After the items have been well hidden the player will be asked to look for them as quickly as possible. The player will be timed as they look for the items. The player will not know how many items are hidden. They will be informed of the point values that are available, but not what the item is that happens to be assigned to that value. The player will decide when they would like to turn in their items and receive their score.

The scoring will work like this:
(non whole numbers will be rounded)

((Point values for items collected * (items collected / total items)) + (time bonus)

The time bonus will work like this:

(total items * 30) - (time taken in seconds)

Here is an example final score:

3 poker chips collected
5 pencils collected
2 golf balls collected

thats 10 out of a total of 15 (5 of each type of item)

thats 425 points for collected items
and that equates to 281 points after the items missed penalty.

and it took 300 seconds.

Lets calculate...

time bonus: (15*30) - (300) = 150

Final: ((425*(10/15)) + 150 = 431

Thats all for now.
