christianp, Here's a game inspired by @two_star's "reverse the list of integers" game.
Get from one integer to another by a sequence of moves. Valid moves are:
- EXPAND: replace a number with an equivalent mathematical expression, e.g. 5 → 1+4
- EVALUATE: replace an expression with its numerical value, e.g. 1+4 → 5.
- SWAP: swap a mathematical operation for another one, e.g. 1+4 → 1×4.
I'll put an example game in the next toot
