Gecko Ballett

A small memory game consisting of just nine cards showing fours geckos each. The geckos on each card have different colors, and every color is on exactly six of the cards.
The cards are shown face up so the players can memorize the geckos, then they are turn face-down.
A color is chosen randomly, and one player asks the other to either turn over four cards showing a gecko of that color, or two colors not showing a gecko of that color.
If the other player manages to do that, they get a point, otherwise not. Then it's the second players turn to randomly choose a color and ask the first player to show or not show geckos in that color.
The game ends after all points are distributed. The player with the most points wins.
