Sticker. Scramble. Callout. 

This is a quick prototype experiment mixing "spot the difference" meets "deduction 2-Player game" mechanics in the simplest form. Ideally could be re-skinned or re-imagined into other contexts. Lots of tweaks could be made and a lot of things learned for future iterations. 

This prototype mocks up the 2nd player.

How to Play: 

1. Decorate. 

You want this to be varied enough to be confusing to memorize but sparse enough to get by the prompts. 

2. Memorize. 

Try your best at memorizing your opponent's card decorations. 

3. Scramble. 

Change your sticker decorations according to the prompts and their limits. You must adhere to all the prompts.

There are four kinds of prompts that you'll see: 
Keep : Priority 1. Change no sticker that matches either this color or shape. 

Lose: Priority 2. If it is not a shape or color in the keep prompt, you must lose at least one sticker with this shape or color.

Add: Priority 3. Add a sticker with this color or shape. 

Move:  Move or change at least one sticker with this color or shape. 

Do note. If it is a shape/color affected by a lose prompt, you will have to replace the sticker with a different shape or color. 

Example: You have to lose a diamond. But you have to move a Rose colored sticker and there's only one Rose -colored diamond on your card. You have to add a Rose-colored heart instead. 

4. Callout 

Your opponent will have chosen to change two out of their three cards. Figure out from those cards as to what prompts they were given. Last selected flipped over card that shows up on the top of the deck is your selected option. 

You can choose to guess or not. If your opponent guesses right and you guess wrong, they get two points. If your opponent guesses right and you don't guess, they get one point. It all depends on how sure you are.  If you both guess correct, neither of you get the point. 

5. Compare

Lastly, time to see what your opponent has guessed. Most correct guesses you win. If you get everything wrong, even if your opponent ALSO get everything wrong you both lose.
