Ascending Fortunes / Stack Up Pays

A long-session machine that behaves much like Regal Riches. It almost never triggers before the go-off number. Colors appear roughly evenly, though green and blue tend to jump by multiple numbers at once more often. These figures are accurate for the original Stack Up Pays but NOT the newer Double version.

Inspect the must-hit-by counters for each color tier so you can read the distance to the go-off number on each one.
