I played both of them. Turing complete has a more non-linear arcade mode. I mean that you can choose which level you want to complete first. There is also soundtrack and a little bit of story line present. There is also gog version of this game. I feel that I learned almost no new skills this semester, but I remember asking my circuit design lecturer questions about this game (in particular, about the possibility of constructing full-adder with fewer elements). That was fun You can stick to nandgame, if you don't want to pay, you loose almost nothing, but playing Turing Complete is more handy because it keeps progress on your computer and/or on the steam account. So, if you clean cookies every time you restart your browser, when using ungoogled-chromium for example, you better play Turing complete. Also one internet friend advised me to play incredible pm https://incredible.pm/ https://incredible.pm/ It is a similar game, but the main theme is proofs rather than digital circuits. Hasn't played yet, unfortunately.
