@Elsa yes, I would be willing to buy the booster since I could undo a bad move/mistake, but also redo a move that required some luck (to set off a chain reaction, for instance). I’d get another chance to roll the dice and cross my fingers for a better outcome. And if this idea was presented before, I apologize, I’m new to…
I counted 17 squares, if we can assume what looks like a square is one. Without measurements, I cannot be certain that anything appearing to be a square actually is one.
