So it says ‘blue’, but it’s printed in red. What’s going on? This fabulous, multi-player brainteaser game has been designed to completely confuse you! Everyone plays at once as you race to match up cards that don’t match, which is far harder than it sounds! None Of A Kind is based on the famous Stroop effect, which was first used in English in 1935 and which measures our ability to process two conflicting pieces of information simultaneously. What do you see when the word ‘green’ is printed in red? Brilliant family fun!
