### Origami Assays Game

The following game uses a small design to illustrate how a pooled assay works. The game is played as follows:
1. Choose either 1 or 2 numbers between 1 and 13. Write them down.
2. Select which of the 10 wells contain your number.
3. The decoder guesses what numbers you have by highlighting them in green . Near matches will be highlighted in gold.

Assay #Samples
5 6 8 13
3 6 7 12
1 6 9 10
4 5 7 11
3 10 11 13
1 2 7 8
8 9 11 12
1 4 12 13
2 4 10
2 3 5 9

#### Why is this impressive?

While this is a small example, stop to consider what it is doing. You are allowed to pick 0, 1, or 2 positive samples and the design is able to decode these all with just 10 assays. If we count them there are:
• 0: 1 If you choose none, then this is 1 configuration.
• 1: 13 If you choose one, then there are 13 configurations.
• 2: 72 If you choose two, then there are 13*12/2=72 configurations.
This means that with just 10 assays we can uniquely identify any one of 86 possible configurations.
