Disc/CounterSlotMachines
Disc and counter slot machines collect physical-looking tokens — discs, orbs, coins, or symbols — that visibly accumulate on the cabinet between players. The collection persists, so each abandoned partial set is leftover value waiting for the next player. The Buffalo Link, Dragon Link, and All Aboard families are well-known disc/counter cabinets, with thresholds and trigger behavior that are heavily mapped out and tracked by advantage play scouts on every floor that runs them.
Mechanics
How disc / counter machines work
Disc-style cabinets show a target number of positions to fill — often 6 of 6 discs, 15 of 15 coins, or a similar 'collect to fill' visual. Special trigger symbols land randomly on the reels and lock into open positions, advancing the count. When all positions are filled, the bonus fires (commonly hold-and-spin or a free-games round). Because the filled positions persist between players, the most valuable cabinets are those left at 4 of 6, 5 of 6, or one disc shy of trigger. Counter-style variants use a numeric tally instead of visible positions but follow the same persistence rule.
