The lesson in plain English
Check where wilds can land and what they replace. Determine whether a multiplier applies to one line, one cluster, one feature, or the whole result. Use a simple example to verify the arithmetic before trusting a headline number. The point is not to drain the fun from the moment. It is to know what moment you are actually having.
Deck note
Confetti is not a calculation. Make the calculation, then enjoy the confetti.
