Abstract:
We present two font designs, each with 37 symbols (letters, digits, and slash), as grid configurations of the same number of coins. Each pair of symbols (say, A and B) forms a puzzle: re-arrange the first symbol (A) into the second (B) by a sequence of moves. Each move picks up one coin and places it in an empty grid cell that is adjacent to at least two other coins (the “2-adjacency” rule). We also present an online puzzle video game to play all 2,664 of these puzzles, where you can try to set the record on the minimum number of moves.
