Tight Slots (slots)
Tight slots will have worse payoffs to a "certified"
high of under 100%, on average over a period time. A machine
not having a symbol, let's say 2-3 cherries, which pay a couple
of coins. These cherries would replace a symbol that doesn't
pay, and presto you have a tight machine. The less paying symbols
a machine has, the smaller the
probability of payouts - thus a tight slot.
