Rummy with stacking building blocks! Create Sets and Runs by combining blocks that range in height of 1 to 7. Sets are made with 3 or 4 blocks of the same size, but different colours. Runs are made up of 3 or more blocks of the same colour in consecutive order. New opportunities come from the ability to stack blocks on top of others to form new heights. Think ahead and make the right decisions, without losing track of whats on the table as you disassemble Runs and Sets to reassemble them into new ones, trying to get rid of your blocks.
