## Triangulation "go fish"

This game is meant for teams.

1. Shuffle the cards and give each player 4 cards. The rest of the deck becomes the draw pile.

2. One team member starts playing. If the four cards in his deck do not ensure enough triangulation along the different axes, he tries to swap a card with another team member by asking for a specific card.

3. If the other does not have it: put one card away at the bottom of the draw pile and draw a new card. When laying off the cards, explain why this one has to go. Then the turn goes to the next player.

4. Repeat steps until one has four cards which he or she regards as optimal. He or she has to defend the optimality of the set to the group.
