WhatIsFreeGames?
Bonus rounds with free spins accumulated by previous play. On some machines, free games are banked and carry over between players, making them a type of accumulator advantage play.
Why It Matters
Why this matters for advantage play
Banked free games are a clean advantage play mechanic — you trigger the bonus on the first spin and harvest spins funded by every prior player. When you find a machine sitting on a meaningful free-games count, the math is usually obvious and the +EV is immediate.

Banked Bonus
A bonus feature that saves progress between players. When a previous player leaves a machine with a partially filled bonus meter, the next player inherits that progress — the core mechanic behind most accumulator advantage plays.
Accumulator
A slot machine that collects or banks a resource (coins, orbs, counters) over time toward a bonus trigger. Previous players' progress carries over, creating advantage play opportunities when the accumulated value is high enough.
Trigger
The specific condition that activates a bonus feature or progressive payout. In AP context, the trigger point is the threshold where playing the machine becomes mathematically profitable.
Counter
A visible or hidden tracker on a slot machine that accumulates toward triggering a feature. Counters may display as collected items, filled meters, or numerical values. When a counter is elevated, the machine may be in a +EV state.
