Students form teams and choose who will go first. They then choose a color, and depending on what is behind said color they receive points as following:
A treasure chest: +5
A coin: +2
A bomb: -3
A thief: steal 2 Pts from another team
The thief appears from the third level onwards. The amount of each item varies per level, with the number of bombs increasing. As I made many levels, it might be best to move on after the treasure is found each time, as I may have made too many levels.
There are hidden slides at the end to make your own levels, simply copy/paste the item, move it behind the color using the animation panel or 'send backwards' option. Finally select the animation for that color and change the sound effect to: treasure: chime, coin: cash register, bomb: explosion, thief: hammer.
Update: I've added a new version which I hope is a little more balanced, with more items.
In case this file is big, here is a google drive link, keep in mind this was made on and designed for PowerPoint.
