The pre-release version of Kleurenkapers! (Colour Capers! in English) contains triangles made of felt and was sold at several different game fairs, including Spiel 2009 in Essen.
Only 20 were made and each copy is numbered and signed by the designer.
Some copies (No. 11, 18, 19 and 20) contain an English manual, instead of a Dutch manual.
