I think you may just need to spell out "each number card is one point" explicitly. It might be more interesting if (say) number cards were worth their value and you only had five "pockets" for gear, so you have a press-your-luck aspect.
See, this is why I like it when people comment. I think your idea of pockets is a great one, so you would have to discard cards to get new bigger numbered cards. That might be something a a longer than one page game could have, I'll have to consider this. lol. I'll see what I can do to change the way it's written to make it obvious.
thank you again!
