I loved the calculator puzzle, mostly because I enjoyed spelling words upside down on the calculator back in school (heck, even now). 5318008

One puzzle that had me going for a while was the blackjack one. I never played it before, so it had me stumped. Then I realized what values the cards really had in the game ( I was thinking J=11, Q=12, K=13 ).
The hardest ones for me would be the star puzzle, where every line must add up to 24. The other one was the second runes puzzle. I gave up on both. @_@
