The shelf behind pixel Daniel Peris's desk is officially full. Consoles, cartridges, controllers and boxed figures from thirty years of collecting are piled on every surface, and a new parcel has just arrived. Miriam suggests a bigger shelf. He suggests the Cartridge Tower instead.
Every piece swings in over the pile in red, blue or yellow, and a careful drop keeps the tower wide while a sloppy one shaves off an edge. The collector's secret is colour: land a piece on one of the same colour and it scores double and wins back a little width. Build it past the collection shelves and up into the night sky. How high can a lifetime of collecting go?
