Wolfgang Warsch has been on quite a streak this year - he designed The Mind, Ganz schön clever, and Die Quacksalber von Quedlinburg - and Illusion is arguably his lightest game, but like the others, it is kind of addicting. Illusion was released several months ago in Germany by publisher Nurnberger-Spielkarten-Verlag (NSV), and the English-language release was at Gen Con by Pandasaurus Games. The twist is that the cards form a sort of optical illusion, and the task is trickier than you’d expect. Illusion is a card game in which players attempt to order cards by the percentage of a color - red, yellow, green, or blue - shown on them.
