Blocks is a 1986 Tower of Hanoi game for the Commodore 64, released (according to GB64) by Robtek Ltd.
This one seems very much like a recolored version of Glen Fisher’s Hanoi. I’d be surprised if it weren’t based on it or one of its successors. As a result, my opinion of this one is the same as with those–it’s functional, but not worth a second look.
