I am fairly sure that Bloxed (
https://wowroms.com/en/roms/acorn-archimedes/bloxed-1995stev... ) on the Archimedes was basically a re-run (maybe an explicit port? I haven't dug in to that, I'm too busy squeeing in gamer here rather than in history nerd) of Bloxeed - I definitely remember most of the same special blocks being there - and it makes an absolutely fantastic single machine two-player tetris plus.
