When I bought my Model 1 back in 1978 - it came with a BASIC program called 'Quick Watson' on tape. I was literally amazed at how this machine could actually play games. I played a lot of those 'Quick Watson' games and so that became a favorite with me. The game is just a different sort of 'Mastermind' game.
Concerning those magazine 'type in games' I did plenty of those, and it required a fair amount of concentration. You needed to be a good typist where there was no need to look away from the magazine, losing your place quickly if you did. If you could type without looking at the keyboard, keeping your eyes on the magazine, there was much less chance for errors. My wife would read back lines to me while I followed along on the screen when it came time to proofread due to some error that was cropping up - and there always were some. I don't think I ever typed a big program in from a magazine that ran right the first time. Them was the 'good old days'.
