The SNES one has a puzzle mode too, I don't know about the NES version. The SNES puzzle mode doesn't let you continue if you used more than the given pieces to solve the puzzle; the GB version lets you use as many as you want but you get a little icon for each one you completed within the target # of pieces. I'm not too big on Tetris 2, but the puzzle mode isn't too bad.

Ah, that means each version (NES, SNES, GB) is slightly different then.  NES version does not have the puzzle mode, just the normal single-player mode with 80 levels and a VS mode.

 

Lmao much of what I say I don’t mean except this anyone want a near mint complete Tetris 2 for game boy lololol
 

Ninja Boy games are unique on GB.
