i'll link to experimental stuff here..
i hope i can get some games here or something!! i like games..
all the folded sections are folded because it can be more interesting to just dive in and try to work out what the thing is yourself i think!!
cards stack when they have identical operators, or the digit is one greater or lesser than the one it is being placed on. e.g. [2+] could stack on [9+], or [5-] could stack on [6*].
the goal is to create expressions that form the numbers shown in the targets list. the expressions are taken in the order digit-operator-digit, noting that each card has both a digit and operator. the stack is evaluated from the bottom card to the top, not considering pedmas.
