Einstein's sister recalled him playing with various toys: “Sehr bezeichnend für seine Anlagen waren nun die Spiele des kleinen Albert. Meist waren es Geduldspiele, Laubsägearbeiten, Erstellung komplizierter Bauten mit dem bekannten Ankersteinbaukasten, am liebsten aber der Bau vielstöckiger Kartenhäuser, womit er seine Musse ausfüllte.” [“The games he played as a child were very characteristic of Albert’s capacities. These were mostly puzzles, fretsaw work, the erection of complicated structures with the well known Anker building blocks, and above all the construction of multi-storeyed card castles, with which he filled his leisure.”] See Maja Winteler-Einstein, 'Beitrag für sein Lebensbild' in: The Collected Papers of Albert Einstein.
