WALDAMI

WALDAMI is a pattern recognition card game. Players start with a hand of seven cards, each of which shows a combination of two forms (inner and outer) in two colors. An example is a combination of an inner circle in white and an outer square in black and white.
The goal of the game hereby is to play all cards of ones hand.

Players do this by adding cards to the ones already played down on the table with the following rules:

change a single shape or color (e.g. circle -> square)
change whole pattern (e.g. inner and outer circle -> inner and outer square)
feature inversion (e.g. inner circle and outer square -> outer square and inner circle)
double feature in version (see 3 plus inversion of color)
