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 documented 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.
Advantage Play
Advantage play tactics for disc / counter
Walk the floor scanning the disc display on each known title. Sit immediately at any cabinet showing one or two positions remaining — these are the most contested seats on the floor. Bet the level documented for full bonus payout (some Link cabinets pay tiered bonuses based on bet). Confirm the bonus fires on a trigger spin before relaxing — a mistimed reset can wipe progress, and properly documented Link play assumes the discs you see are real.
